- Programmer/board type: e.g , Stlink/v2-onboard
- Programmer firmware version: e.g STSW-LINK007 2.27.15
- Operating system: e.g Linux
- Stlink tools version and/or git commit hash: st-flash 1.4.0-25-ge9fe4e5
- Stlink commandline tool name:
st-flash - Target chip (and optional board): e.g STM32F469I-DISCO
Fails to flash with some HEX files.
Tested the HEX file provided by ST in the CubeMX archive.
Output:
st-flash --serial 303636424646333533353335344433 --format ihex write STM32469I-Disco_Demo_V1.2.0.hex
st-flash 1.4.0-25-ge9fe4e5

Reply to myself: the binary may contain data that are located in an external memory. OpenOCD also fails to flash at weird addresses. The official STLink does have support of that for discovery boards.
If that is a EEPROM or OTP area it is not possible in the same hex file with openocd and stlink currently. Because they use different algorithms to program.
Yes for sure. Anyway maybe we could have a proper error message. I have tested with my own program, it is OK, either close this ticket or change it to a "nice to have" status.
Closed due to inactivity and missing interest.
