flashing STM32H743VTIx from linux commandline
It seems to me that st-flash still have not got any support for STM32H7xx devices yet
Is there other command line options available that run under Ubuntu? Could be payware even.. I have both stlink/v2 and a segger j-link (EDU version) available but have not been able to flash using these tools.
Openocd seems to be an debugger only if I am right
EDIT:
Found source of st-flash and built version 1.6.1, seems to work

But, since I cant delete posts, i rather update with some info
