Hmm, there is some rumor that Linux debugging isn't possible as long as we don't have proper Cortex A8 cache and MMU support. If I remember correctly, Magnus always talked about "with this only U-Boot debugging is possible". Sorry if I missed something or if I'm completely wrong here ;) Best regards Dirk _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
