Hello,

I am not a regular user of stlink, so please excuse the naivity of the question.

I have received a prototype board and an stlink-v2 dongle. I need to flash the prototype board with a specific bootloader using st-flash. I am using Ubuntu 18.04.

I have compiled the nightly build and the development version of stlink without issues hoping that one of the two versions would allow me to do the job with the command "st-flash binary.bin address"

Unfortunately, it does not work, the sd-ram memory on the board is erased but the bootloader is unable to load

"2020-09-26T13:17:19 ERROR flash_loader.c: unknown coreid, not sure what flash loader to use, aborting! coreid: 2ba01477, chipid: 414"

(see full console extract below).

I had a search on the list of issues and my hint is that it is probably required to modify one of the files and recompile st-link so my prototype board with coreid: 2ba01477, chipid: 414 is supported, but I have no idea what needs to be updated/patched. If someone could guide me into this, it would very much appreciated.

Thanks
Regards
Peter
