When I connect to my target board (C5409A DSP in MP mode) and try to write (e.g. PMST) register either from GEL, or direct via registers view window its value chanches at the begining, but then resets to 0xfc00. Memory Mapping is disabled. All the memory gives value 0xfc00.
Is it possible to change CPU registers at all? May be something wrong with my JTAG Emulator (XDS510-USB)?
Regards.
