The S3C2440 is possibly the worst timer implementation: it is the only timer supported by the I-pipe patch not based on clockevents. It seems this platform is not really maintained. Also, if you want to port the I-pipe patch to a new board, I would advise you to start with the I-pipe core patch. The timer handling has changed a lot. The code for core-3.2 is available here: http://git.denx.de/?p=ipipe.git;a=shortlog;h=refs/heads/core-3.2 -- Gilles. _______________________________________________ Xenomai mailing list [email protected] http://www.xenomai.org/mailman/listinfo/xenomai
