I do not find any cpu.c. The Denx Qong box probably has the same issue as imx25, and I would be interested in fixing it. > > Maybe the complete BSP with ipipe for the iMX25 and 2.6.28 kernel > might be interesting for release (similar as the patch > ipipe-2.6.26-mxc.diff), but is still in an early development state: > now the latency app runs I see it runs fine only for a few minutes and > then gets overruns... asks for debugging ;-) Ok. You can try and use the I-pipe tracer. And make sure to run latency -p 1000. I can have a look at your I-pipe code to see if I do not see anything obvious. -- Gilles
