[I] NSH: startup script crash [nuttx]
maxikrie opened a new issue, #12013:
URL: https://github.com/apache/nuttx/issues/12013
Hello,
I am trying to run a startup script from a SD Card. I have followed the instructions for enabling the startup and everything works in principle however sometimes it crashes.
I created the nsh_romfsimg.sh from an empty rc.sysinit.template and rcS.template contains
```
mount -t vfat /dev/mmcsd0 /mnt/sdcard
sh /mnt/sdcard/startup/startup.txt
```
The startup script contains
`echo hello`
Sometimes this crashes with the following output
```
_assert: Assertion failed panic: at file: :0 task: sh 0x802f4f1

```
It seems that there is a stack overflow for the 'sh' command, but I cannot find where the stack is allocated for this.
When I execute the command from the shell after startup (for the case it went through), I haven't yet observed a crash.
Thanks!
Max
