If it works, it will be dead slow, but we might get more diagnostics if the offending code runs on the PC instead of the target. If it fails, too, please provide a log of the failing operation that shows the bus cycles. BTW: you *did* set up the work area to point to an area where you have working memory? cu Michael _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
