Starting from version 0.4, the back-end of stm32flash is modular and ready to be expanded to support new interfaces. I'm planning adding SPI on Linux through standard driver "spidev". You are invited to contribute with more interfaces. To add a new interface you need to add a new file, populate the struct port_interface (check at the end of files i2c.c, serial_posix.c and serial_w32.c) and provide the relative functions to operate on the interface: open/close, read/write, get_cfg_str and the optional gpio. The include the new drive in Makefile and register the new struct port_interface in file port.c in struct port_interface *ports[]. There are several USB-I2C adapter in the market, each providing its own libraries to communicate with the I2C bus. Could be interesting to provide as back-end a bridge between stm32flash and such libraries (I have no plan on this item). Add new STM32 devices: ===================================================================== Add a new line in file dev_table.c, in table devices[]. The fields of the table are listed in stm32.h, struct stm32_dev. Cross compile on Linux host for Windows target with MinGW: ===================================================================== I'm using a 64 bit Arch Linux machines, and I usually run: make CC=x86_64-w64-mingw32-gcc AR=x86_64-w64-mingw32-ar stm32flash-0.5+git20200914+2b0f078/I2C.txt000066400000000000000000000074771372775330000170750ustar00rootroot00000000000000About I2C back-end communication in stm32flash ========================================================================== Starting from version v0.4, beside the serial communication port, stm32flash adds support for I2C port to talk with STM32 bootloader. The current I2C back-end supports only the API provided by Linux kernel driver "i2c-dev", so only I2C controllers with Linux kernel driver can be used. In Linux source code, most of the drivers for I2C and SMBUS controllers are in ./drivers/i2c/busses/ Only I2C is supported by STM32 bootloader, so check the section below about SMBUS. No I2C support for Windows is available in stm32flash v0.4. Thanks to the new modular back-end, stm32flash can be easily extended to support new back-ends and API. Check HOWTO file in stm32flash source code for details. In the market there are several USB-to-I2C dongles; most of them are not supported by kernel drivers. Manufacturer provide proprietary userspace libraries using not standardized API. These API and dongles could be supported in feature versions. There are currently 3 versions of STM32 bootloader for I2C communications: - v1.0 using I2C clock stretching synchronization between host and STM32; - v1.1 superset of v1.0, adds non stretching commands; - v1.2 superset of v1.1, adds CRC command and compatibility with i2cdetect. Details in ST application note AN2606. All the bootloaders above are tested and working with stm32flash. SMBUS controllers ========================================================================== Almost 50% of the drivers in Linux source code folder ./drivers/i2c/busses/ are for controllers that "only" support SMBUS protocol. They can NOT operate with STM32 bootloader. To identify if your controller supports I2C, use command: i2cdetect -F n where "n" is the number of the I2C interface (e.g. n=3 for "/dev/i2c-3"). Controllers that supports I2C will report I2C yes Controller that support both I2C and SMBUS are ok. If you are interested on details about SMBUS protocol, you can download the current specs from http://smbus.org/specs/smbus20.pdf and you can read the files in Linux source code ./Documentation/i2c/i2c-protocol ./Documentation/i2c/smbus-protocol About bootloader v1.0 ========================================================================== Version v1.0 can have issues with some I2C controllers due to use of clock stretching during commands that require long operations, like flash erase and programming. Clock stretching is a technique to synchronize host and I2C device. When I2C device wants to force a delay in the communication, it push "low" the I2C clock; the I2C controller detects it and waits until I2C clock returns "high". Most I2C controllers set a "timeout" for clock stretching, ranging from few milli-seconds to seconds depending on specific HW or SW driver. It is possible that the timeout in your I2C controller is smaller than the delay required for flash erase or programming. In this case the I2C controller will timeout and report error to stm32flash. There is no possibility for stm32flash to retry, so it can only signal the error and exit. To by-pass the issue with bootloader v1.0 you can modify the kernel driver of your I2C controller. Not an easy job, since every controller has its own way to handle the timeout. In my case I'm using the I2C controller integrated in the VGA port of my laptop HP EliteBook 8460p. I built the 0.25$ VGA-to-I2C adapter reported in http://www.paintyourdragon.com/?p=43 To change the timeout of the I2C controller I had to modify the kernel file drivers/gpu/drm/radeon/radeon_i2c.c line 969 - i2c->bit.timeout = usecs_to_jiffies(2200); /* from VESA */ + i2c->bit.timeout = msecs_to_jiffies(5000); /* 5s for STM32 */ and recompile it.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs.

It requires the STM32 to embed a bootloader compliant with ST application note AN3155 or AN4221. .B stm32flash uses the serial port .I tty_device or the i2c port .I i2c_device to interact with the bootloader of STM32. .SH OPTIONS .TP .BI "\-a" " bus_address" Specify address on bus for .IR i2c_device . This option is mandatory for I2C interface. .TP .BI "\-b" " baud_rate" Specify baud rate speed of .IR tty_device . Please notice that the ST bootloader can automatically detect the baud rate, as explained in chapter 2 of AN3155. This option could be required together with option .B "\-c" or if following interaction with bootloader is expected. Default is .IR 57600 . .TP .BI "\-m" " mode" Specify the format of UART data. .I mode is a three characters long string where each character specifies, in this strict order, character size, parity and stop bits. The only values currently used are .I 8e1 for standard STM32 bootloader and .I 8n1 for standard STM32W bootloader. Default is .IR 8e1 . .TP .BI "\-r" " filename" Specify to read the STM32 flash and write its content in .I filename in raw binary format (see below .BR "FORMAT CONVERSION" ). .TP .BI "\-w" " filename" Specify to write the STM32 flash with the content of .IR filename . File format can be either raw binary or intel hex (see below .BR "FORMAT CONVERSION" ). The file format is automatically detected. To by\-pass format detection and force binary mode (e.g. to write an intel hex content in STM32 flash), use .B \-f option. .TP .B \-u Specify to disable write\-protection from STM32 flash. The STM32 will be reset after this operation. .TP .B \-j Enable the flash read\-protection. .TP .B \-k Disable the flash read\-protection. .TP .B \-o Erase only. .TP .BI "\-e" " num" Specify to erase only .I num pages before writing the flash. Default is to erase the whole flash. With .B \-e 0 the flash would not be erased. .TP .B \-v Specify to verify flash content after write operation. .TP .BI "\-n" " count" Specify to retry failed writes up to .I count times. Default is 10 times. .TP .BI "\-g" " address" Specify address to start execution from (0 = flash start). .TP .BI "\-s" " start_page" Specify flash page offset (0 = flash start). .TP .BI "\-S" " address" "[:" "length" "]" Specify start address and optionally length for read/write/erase/crc operations. .TP .BI "\-F" " RX_length" "[:" "TX_length" "]" Specify the maximum frame size for the current interface. Due to STM32 bootloader protocol, host will never handle frames bigger than 256 byte in RX or 258 byte in TX. Due to current code, lowest limit in RX is 20 byte (to read a complete reply of command GET). Minimum limit in TX is 5 byte, required by protocol. .TP .B \-f Force binary parser while reading file with .BR "\-w" "." .TP .B \-h Show help. .TP .B \-c Specify to resume the existing UART connection and don't send initial INIT sequence to detect baud rate. Baud rate must be kept the same as the existing connection. This is useful if the reset fails. .TP .BI "\-i" " GPIO_string" Specify the GPIO sequences on the host to force STM32 to enter and exit bootloader mode. GPIO can either be real GPIO connected from host to STM32 beside the UART connection, or UART's modem signals used as GPIO. (See below .B BOOTLOADER GPIO SEQUENCE for the format of .I GPIO_string and further explanation). .TP .B \-C Specify to compute CRC on memory content. By default the CRC is computed on the whole flash content. Use .B "\-S" to provide different memory address range. .TP .B \-R Specify to reset the device at exit. This option is ignored if either .BR "\-g" "," .BR "\-j" "," .B "\-k" or .B "\-u" is also specified. .SH BOOTLOADER GPIO SEQUENCE This feature is currently available on Linux host only. As explained in ST application note AN2606, after reset the STM32 will execute either the application program in user flash or the bootloader, depending on the level applied at specific pins of STM32 during reset. STM32 bootloader is automatically activated by configuring the pins BOOT0="high" and BOOT1="low" and then by applying a reset. Application program in user flash is activated by configuring the pin BOOT0="low" (the level on BOOT1 is ignored) and then by applying a reset. When GPIO from host computer are connected to either configuration and reset pins of STM32, .B stm32flash can control the host GPIO to reset STM32 and to force execution of bootloader or execution of application program. The sequence of GPIO values to entry to and exit from bootloader mode is provided with command line option .B "\-i" .IR "GPIO_string" . .PD 0 The format of .IR "GPIO_string" " is:" .RS GPIO_string = [entry sequence][:[exit sequence]] .P sequence = [[\-]signal]&|,[sequence] .RE .PD .P In the above sequences, negative numbers correspond to GPIO at "low" level; numbers without sign correspond to GPIO at "high" level. The value "n" can either be the GPIO number on the host system or the string "rts", "dtr" or "brk". The strings "rts" and "dtr" drive the corresponding UART's modem lines RTS and DTR as GPIO. The string "brk" forces the UART to send a BREAK sequence on TX line; after BREAK the UART is returned in normal "non\-break" mode. Note: the string "\-brk" has no effect and is ignored. .PD .P The ',' delimiter adds 100 ms of delay between signal toggles, whereas the '&' delimiter adds no delay. An empty signal, thus repeated ',' delimiters, can be used to insert larger delays in multiples of 100 ms. E.g. "rts,,,,\-dtr" will set RTS, then wait 400 ms, then reset DTR. "rts&\-dtr" will set RTS and reset DTR without delay. You can use ',' delimiters alone to simply add a delay between opening port and starting to flash. .DP .P Note that since version 0.6, an exit sequence will always be executed if specified, regardless of the -R option, to ensure the signals are reset. If -R is specified, but no exit sequence, a software-triggered reset will be performed. .PD 0 As example, let's suppose the following connection between host and STM32: .IP \(bu 2 host GPIO_3 connected to reset pin of STM32; .IP \(bu 2 host GPIO_4 connected to STM32 pin BOOT0; .IP \(bu 2 host GPIO_5 connected to STM32 pin BOOT1. .PD .P In this case, the sequence to enter in bootloader mode is: first put GPIO_4="high" and GPIO_5="low"; then send reset pulse by GPIO_3="low" followed by GPIO_3="high". The corresponding string for .I GPIO_string is "4,\-5,\-3,3". To exit from bootloader and run the application program, the sequence is: put GPIO_4="low"; then send reset pulse. The corresponding string for .I GPIO_string is "\-4,\-3,3". The complete command line flag is "\-i 4,\-5,\-3,3:\-4,\-3,3". STM32W uses pad PA5 to select boot mode; if during reset PA5 is "low" then STM32W will enter in bootloader mode; if PA5 is "high" it will execute the program in flash. As example, supposing GPIO_3 connected to PA5 and GPIO_2 to STM32W's reset. The command: .PD 0 .RS stm32flash \-i '\-3&\-2,2:3&\-2,,,2' /dev/ttyS0 .RE provides: .IP \(bu 2 entry sequence: GPIO_3=low, GPIO_2=low, 100 ms delay, GPIO_2=high .IP \(bu 2 exit sequence: GPIO_3=high, GPIO_2=low, 300 ms delay, GPIO_2=high .PD GPIO sequence to bring delays on start after port opening. The command: .PD 0 .RS stm32flash \-i ',,,,,:rts&\-dtr,,,2' /dev/ttyS0\n", .RE provides: .IP \(bu 2 entry sequence: delay 500 ms .IP \(bu 2 exit sequence: RTS=high, DTR=low, 300 ms delay, GPIO_2=high .PD .SH EXAMPLES Get device information: .RS .PD 0 .P stm32flash /dev/ttyS0 .PD .RE Write with verify and then start execution: .RS .PD 0 .P stm32flash \-w filename \-v \-g 0x0 /dev/ttyS0 .PD .RE Read flash to file: .RS .PD 0 .P stm32flash \-r filename /dev/ttyS0 .PD .RE Start execution: .RS .PD 0 .P stm32flash \-g 0x0 /dev/ttyS0 .PD .RE Specify: .PD 0 .IP \(bu 2 entry sequence: RTS=low, DTR=low, DTR=high .IP \(bu 2 exit sequence: RTS=high, DTR=low, DTR=high .P .RS stm32flash \-i \-rts,\-dtr,dtr:rts,\-dtr,dtr /dev/ttyS0 .PD .RE .SH FORMAT CONVERSION Flash images provided by ST or created with ST tools are often in file format Motorola S\-Record.
