If you press enter a few time in the serial terminal do you get the nsh> prompt? There might been some buffer issue. I use screen, but that should not be a problem.
If this does not work you will likely need to use a debugger like gdb to see if you are actually getting to the shell. You can use the openocd to start gdb (this openocd config works for both the h745 and h743 boards). The one you used is out dated which is why you got the error. openocd -f board/stm32h745i-disco.cfg You may want to refer to some of the documentation here to use gdb with this. Note that you will at a minimum want to enable debug symbols in your build. https://nuttx.apache.org/docs/latest/quickstart/debugging.html#debugging-with-openocd-and-gdb With gdb you will want to use the nuttx file instead of the nuttx.bin as it is the elf. I would recommend starting with nsh_main as the breakpoint, but you may need to dig earlier. --Brennan On Tue, Aug 10, 2021, 11:53 PM rushi ghatkar <rushighatka...@gmail.com> wrote: > Hi Brennan Sir, > > > Thank you for your help. > > So, am I missing something?
