Boundary scan does not offer any debugging features. It gives you control over the external pins of the device. > I would also like to use GDB in order to debug the target so would looking > at the ARM GDB Server be a start to figure out how to port such a thing to > the SC520? Debugging requires support from dedicated on-chip debug circuitry. Apparently the Elan SC520 has something they call "AMDebug", which probably does what you want, but I'm not sure if the necessary information is publicly available. > I've always been a user of commercial JTAG products and now want to learn > how this all really works so I can tinker with boards at home on a low cost > basis. > > Thank you! > > Brian Best regards, Dominic _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
