I'm employing 51822AA.
I need to debug firmware for this chip line by line. Like environment of ARM9 with Lauterbach TRACE32 through JTAG.
Is line debugging possible with Segger's JTAG Base through just 4 pins(GND, VRF, DIO, CLK)?
Or any reference circuit design capable of line debugging with any in-circuit-debugger?
I can't see any change of data in real time.
