(this tool would not compile as is so my changes are at https://github.com/rusefi/hex2dfu) (this comes from https://github.com/encedo/hex2dfu)
hex2dfu
Simple command line tool to convert file format from Intel HEX to STM32 DFU.
Compile
hex2dfu is a single C file application and can be easly compile by any ANSI C compiler. No makefile required. Just type:
gcc hex2dfu.c -o hex2dfu.exe
I`m using mingw32 under Windows, change parameters regards your enviroment.
To enable ED25519 code signing feature, download ED25519 code from https://github.com/encedo/ed25519 or https://github.com/orlp/ed25519 to folder ED25519 and type:
gcc hex2dfu.c ED25519/*.c -o hex2dfu.exe
Using
-
Simple convertion
hex2dfu.exe -i infile.hex -o outfile.dfu
-
Convertion with changing VID/PID
hex2dfu.exe -i infile.hex -o outfile.dfu -p 0x0483 -v 0xdf11
-
As before with extra device version included (otherwise 0xFFFF will be placed)
hex2dfu.exe -i infile.hex -o outfile.dfu -p 0x0483 -v 0xdf11 -d 0x1234
-
EXTRA: Calculated CRC32 of the file and embed meta data at given address
hex2dfu.exe -i infile.hex -o outfile.dfu -c 0x08011000
-
Code siging: To sign the code ED25519 'secret' need to be provided
hex2dfu.exe -i infile.hex -o outfile.dfu -c 0x08011000 -S d4411fa9d5cb6f91b7bd18e4ab41e7d03bf37e1d738c12b923ef0f09de90e6cf
-
Like above but extra data (-P) are added:
hex2dfu.exe -i infile.hex -o outfile.dfu -c 0x08011000 -S d4411fa9d5cb6f91b7bd18e4ab41e7d03bf37e1d738c12b923ef0f09de90e6cf -e -P DEADBEEF
-
Like above but additional data are public key based on signing secret:
hex2dfu.exe -i infile.hex -o outfile.dfu -c 0x08011000 -S d4411fa9d5cb6f91b7bd18e4ab41e7d03bf37e1d738c12b923ef0f09de90e6cf -e
Automated CRC32 generation in very usefull when custom bootloader is in use. We can check firmware at every MCU boot and execute only when file ingerrity is authenticated. Otherwise performe failover (e.g. start USB bootloader).
Custom USB Bootloader supporting CRC32 checking during boot will be open sourced soon. Stay tuned :)
