All ARM7TDMI cores seem to use the same IDCODE values, modulo core revision. That caught me by surprise too, at first.

OpenOCD has a rather understandable focus on the latter... _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
