[Skimmertalk] Red Pitaya Input 2

[DD5XX (Saki)]

Wes,

you need to execute "rw" command before you try editing the file. This
is because the filesystem is read-only in default state. Whenever you
want to make permanent changes, you need to enter "rw" in shell prompt
and THEN enter your "vi" command to edit the appropriate file.

Good luck and 73
Saki, DD5XX
