Just some thoughts on multicore interface to debuggers... GDB server: Today OpenOCD has support for multiple CPUs that lends itself towards heterogeneous multiprocessor systems. I don't think there are many of those that OpenOCD can support. Also the current support creates one GDB server for eac

Thanks to everyone that provided feedback about the status of OpenOCD's support for Cortex-A8. I have made some notes and started hacking on some low-hanging fruit. Proper support for ROM Table scanning to discover the debug topology seems to be high on the list of necessary improvements to push Co
