    Thank you for the support we were able to solve the issue. Let's close this thread. Solution: JTAG_MOD needed to be connected to ground, and J-Link 10pin needed the reset (pin10) disconnected.

    Thank you for the response. It looks like I can try the second option first. Do you have a procedure to change IRLen value by changing boundary scan mode to some other mode? I found the procedure to change to the boundary scan mode with Lauterbach JTAG debugger: nxp.com/docs/en/application-note/AN12919.pdf Do you have something similar for Segger J-Link? Please let me know. Thank you.
