hi,

does that mean, that the ARM isn't trying to get a sync on a channel after
the initialization?
i have the problem that it produces 'outcommand errors' all the time and a
little bit later the ARM is crashing if there is no sync on the channel..

if the changes you want to do avoid the ARM from crashing if there is no
sync, PLEASE DO SO... ;)

regards
joerg
