The Uv3 simulator and JTAG debugger use the wrong SFR symbols for the LPC213X ARM processors. It appears the symbols for the LPC210x are used. I've changed the device database for the LPC2138 to show the proper register file (LPC213x.h), but that doesn't change anything. The symbols listed in the View->Symbols window are still those for the 211x. Can anyone point me in the right direction? Many thanks in advance. Dave Sidlauskas
