I just got an XDP emulator, now the emulator tells me that the code has been correctlycopied to the CAR region, which is 0xc0000, I can see the code through both disassembly window and the data window, but when I try to step on the first instruction, source-point pops up a window saying 'memory access failed', then the emulator connection is lost. btw, the simulator is an ARIUM ECM-XDP3, I've followed the advice in its manual to set 0xc0000 to be a SRAM region. so, is the XDP lying to me? or I missed some points? @Stefan: I'm trying to port v2 to several grantsdale/calistoga boards that we manufactured.
