Hi Wolfgang
May I ask one further question re. the BDI2000? An article on the internet states:
"You might be wondering why the BDI2000 only works with kernel-mode code and not user-land application code. The technical details are beyond the scope of this AppNote. The 10,000 foot answer is that while the BDI2000 can work with the MMU enabled, it can only work with a single continuous memory map. Kernel-mode code exists in a single continuous memory map, which is disjoint from all of the user-land process memory maps. As an example of the usefulness of this tool in production environments, the PPC porting engineers at Monta Vista Software use the BDI2000 extensively for kernel bring-up and device driver debug"
Is it true that the BDI is not suitable for user app debug? Is this a problem in practice?
My US$0.02...
I'm not personally aware of the issues using the BDI2000 to debug user space code. But in practice you do not need a hardware debugger to debug user space code. Just use gdb and/or gdbserver to debug your user space code.
