[Skimmertalk] Red Pitaya SDR 122-16 tips

[Björn Ekelund]

Bob,

Alpine in Pavel's image runs in RAM so you have to manually back up any
changes (like the copied start.sh or changes to /etc/motd) to the memory
card using

$ lbu commit -d

Or they will be forgotten at next boot.

You will find more information here
