My embedded linux application is running with the linux file system set
to read-only, so I don't get in trouble just shutting the system off.
However, I would like to store certain data (calibration data) on this
CF disk, but to do so I would have to jump out of read-only, write the
data to a file and then go back to read-only. My question is: Can I do
this from the running application? Currently I am just doing it by hand
in a terminal window.

Please advise,

Jens.
