If XMPU/XPPU are configured to block accesses to a peripheral/memory through a processor or DAP, accessing such addresses thru these targets in XSDB leads to memory access errors. Memory accesses succeed only when the hardware is configured to allow access from the active target to that address. Users must use 'loadhw' or 'memmap' commands that provides access to the protected memory regions. Alternatively, '-force' option in 'mrd'/'mwr' commands can be used or set 'force-mem-access' in 'configparams' to 1.
