STM32CubeProgrammer (Win64) has problem to read .HEX file with multiple dot

[Alamy]

Due to Company policy, one must use Windows. (board is seen by Windows)

Due to ARM, development is Linux based.

Therefore: WSL / WSL2

• Please don't tell me to run Linux tools inside WSL2, many Linux GUI tools crash
• Please don't tell me to export Win USB devices into WSL2, the driver doesn't support all protocols yet.

 

The developing environment are in WSL2. I have output files

\\wsl.localhost\Ubuntu\home\user\stm32h757i\build\
|-- cm4/      # cm4 files
`-- cm7/      # cm7 files

stm32h757i_eval.cm4.bin / stm32h757i_eval.cm7.bin <-- No problem to program those files

stm32h757i_eval.cm4.hex / stm32h757i_eval.cm7.hex <-- BAD00001 not aligned error

stm32h757i_eval_cm4.hex / stm32h757i_eval_cm7.hex <-- No problem to program those files.

Note

• The contain in the .HEX file has no problem
• It seems the STM32CubeProgrammer has problem to handle multiple dot '.' .hex file
• Symbolic won't work (STM32CubeProgrammer won't recognize it)

Workaround

• Copy stm32h757i_eval.cm4.hex to stm32h757i_eval_cm4.hex get it to work.

CLI (STM32_Programmer_CLI.exe) the same

flash.sh

export PROGRAMMER_CLI="/mnt/c/Program Files/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin/STM32_Programmer_CLI.exe"

PROGRAMMER_PARMS="-c port=SWD sn=002E00273132510838363431 freq=8000 mode=NORMAL reset=SWrst speed=Reliable"

"${PROGRAMMER_CLI}" ${PROGRAMMER_PARMS} -w "${FILE} -hardRst"

 

$ bash flash.sh prj.stm32h757i_eval.hex

Would obviously be better fixed.

Perhaps the script could copy to a temp file, or you could write a small app to merge the .hex files, or use SRECORD

The problem is the filename.

I do have determined what kind of filename that STM32CubeProgrammer could accept and applied the workaround already.

FYI: I also found that it could only accept file in the current folder (without path).
