Can anyone help me?
Are you sure it's not a kernel oops (you'll see it in dmesg)? They generally end up segmentation faulting the process. Also, could it be related to the recent thread on CMEM not being able to get the physical address of non-cmem buffers? I believed Robert resolved it with the code at the end of http://linux.omap.com/pipermail/davinci-linux-open-source/2007-October/004346.html Cheers, Bernard. _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
