We have a control micro within the BDM header which talks to the PC via a proprietary protocol (H/W and S/W). This means we end up talking to the CPU32 BDM interface ALOT faster than the standard Motorola cable - in fact we measure our own debugger (under Windows) downloading into target memory at 37KB/sec for a 20MHz CPU32 system. We have also implemented a 'dynamic' memory access system whereby the target memory is accessible during execution. This is not real time BUT target intrusion is kept to a minimum since the break,access,re-execute sequence is under control of the micro (20MHz PIC) in the BDM header - not the PC! We dont have a Linux/gdb driver for our BDM unit, BUT if anyone wants to do one we would provide them with all the information required (this also applies to Coldfire).
