Hi folks,

I just got a core board that I am trying to get working. The JTAg circuit that I have implemented does not recognize the board. Can someone tell me the mininum pins that I need to connect from the core board to get JTAG working? Right now, I only have the JTAG pins, Vcc and GND connected. I have also grounded OM1, OM2, and OM3. Finally, I have pulled OM0 high (NOR flash boot).

What am I missing?

Thanks in advance for your help.

Did you check this thread viewtopic.php?f=6&t=45 for configuring the software.

I know for sure that the software works as it detects the processor on my dev. board correctly. I am building a new circuit from scratch using the core board and trying to get the JTAG circuit working.

Issue resolved after circuit rework. You actually only need the 6 JTAG wires, power, and ground.
