Openblt deliver (#3486) 
* common_make: rusefi.* should be functional image

OpenBLT used: rusefi.* is bootloader plus RusEFI
OpenBLT not used: rusefi.* is RusEFI only.
In both cases flashing of rusefi.* image to blank device should be
enough.
rusefi_update.srec does not include bootloader and this image should
be used for CAN update.

* Boundle generation: include bootloader and update image

* Update hex2dfu, deliver composite bin file

README.md

(this tool would not compile as is so my changes are at https://github.com/rusefi/hex2dfu) (use gcc hex2dfu.c -o hex2dfu.exe to compile) (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

  1. Simple convertion

    hex2dfu.exe -i infile.hex -o outfile.dfu

  2. Convertion with changing VID/PID

    hex2dfu.exe -i infile.hex -o outfile.dfu -p 0x0483 -v 0xdf11

  3. 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

  4. EXTRA: Calculated CRC32 of the file and embed meta data at given address

    hex2dfu.exe -i infile.hex -o outfile.dfu -c 0x08011000

  5. Code siging: To sign the code ED25519 'secret' need to be provided

    hex2dfu.exe -i infile.hex -o outfile.dfu -c 0x08011000 -S d4411fa9d5cb6f91b7bd18e4ab41e7d03bf37e1d738c12b923ef0f09de90e6cf

  6. Like above but extra data (-P) are added:

    hex2dfu.exe -i infile.hex -o outfile.dfu -c 0x08011000 -S d4411fa9d5cb6f91b7bd18e4ab41e7d03bf37e1d738c12b923ef0f09de90e6cf -e -P DEADBEEF

  7. 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 :)
