Remote DDD works fine except for one fatal flaw ... I can't single step flash. It single steps code loaded into RAM. Since both insight and DDD are really just shells talking to gdb talking to ocdremote (gdbserver workalike) it seems clear that my problem is I haven't configured gdb to use hardware breakpoints while single stepping, but I've searched and searched and googled and googled and can't find anything other than hbreak. What am I missing?
Unfortunately I don't work with GDB related debuggers but on the Lauterbach TRACE32 ICD there are two possibilities for setting hardware breakpoints; first you can specify it by an additional parameter called /onchip. Second you you define a memory map with the attributes map.readonly or map.bonchip (which are internally the same). I expect that similar attributes exist for GDB. Unfortunately not all ARM related debugging features are implemented properly on GDB; that's why I prefer Lauterbach debuggers. IIRC they allow also to set software breakpoints in certain Flash memory devices.
