I try to do my own compilation with H7 cam, and it works, ouhou !
I did it with a virtuallbox i had with ubuntu and qtcreator than i use for F7 cam.
For debugging with openocd (0.10.0), gdb-server and baremetal, i downloaded a stm32h7x.cfg here :
and added it to qtcreator options but i have this error before debugging : invalid command name ‘dap’
than i supposed coming from line 37 of cfg file: dap create _CHIPNAME.dap -chain-position _CHIPNAME.cpu
Have you used another cfg file for H7 file ?
I am a bit lost, and any help could be welcome.
