I have an ADB 3000 ( telestraclear) That I need to JTAG to try and get the IRD/BK . There is a 20 pin connector. The jTAG pins are 2,4,6,16 and 18 + ground. I have taken off the BGA and found that the pins connect to :-
AF6 ( I think)
AE6 ( I think).
TRST is on PIN 4 on the JTAG connector.
Can anyone help in naming the CPU pins, i.e. is R23 TDO? etc.
Do I need to ground one of the processor pins to enable JTAG to connect so I can read memory.?
I'm not convinced that the CPU pins are correct, because usually the JTAG pins are all together/side by side, ....But I buzzed out the connections from the JTAG connector pins to all the pins on the BGA...and that's what I got.
