[Skimmertalk] Red Pitaya Input 2

[Bob Wilson, N6TV]

Yes, that's it:

*rw*
*nano start.sh*, make changes, Ctrl-X to exit, *Yes* to save
*ro* to restore read-only status
*./stop.sh*
*./start.sh*

Of course don't forget to move the jumper on input 2.

73,
Bob, N6TV

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
