thanks,Daniel, there are some incorrect information about this soc, through smbus interface, cpu core registers, such as status register, register files r0-rx could not be accessed, all other peripheral registers can be accessed,including breakpoint enable/disable. with these restrictions, is it still possible to do such a converter to support source level debuging? thank you. Rick

Probably. You should write a convertor between your SMBus debug interface and the GDB remote protocol, and then connect GDB to it over TCP.
