I am trying to run nuttx on STM32F429IDisco device. I am following tutorial from nuttx official channel on youtube. Few days ago i was not able to start minicom. But after some study i was able to start it, using /dev/stlinkv2_2.

https://stackoverflow.com/questions/45627751/minicom-is-not-starting

Anyway, at this moment i am stuck at very next step. My minicom have succesfully started but i can't start nsh to run my programs by clicking reset button.

Can anybody tell me what is the wrong i have done ? stlinkv2_2 isn't right way to setup device? or any other mistake?

My development Environment: Ubuntu 16.04

You will have to either turn on some debug options to get some output for use a SWD debugger to get more information.

Enabling debug output can interfere with USB operation since it I very time critical. NuttX supports a built-in USB trace feature that, although cryptic, can instrument USB without being so evasive. There is some discussion of that trace feature here:
