I've never seen that. It should be easy enough for someone who can reproduce that to figure out what line of code that address indicates. My only suggestion is that it's very early in that routine, and it looks like the DMA controller startup code may not be quite right after the signature change. Around line 1983 of musb_core.c try making the c->start() pass "c", not "c->private_data". - Dave _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
