Re: CONFIG_NSH_CMDPARMS not working as expected

[Gregory Nutt]

I can't execute:

echo ":-)" > /test.txt
"nsh: echo: open failed: No such file or directory"

The root file system is not a "real" file system.  It is a pseudo-file 
system and you cannot create regular files there.  See 
https://cwiki.apache.org/confluence/display/NUTTX/Pseudo+File+System (a 
little out of date).
