J-Link not connecting to EVAL-ADV7612EB1Z NXP board

I have got an NXP based ADV7612 eval board and a J-Link SWD emulator. I am not able to connect the J-link to the uController. IAR always gives an error 'TDO always high' and fails to load. I probed the TDO pin and it does not toggle at all during the JTAG communication (loading, scanning etc.). The board boots up correctly with the flashed application (ADI HDMI Repeater Application). The same emulator connects with another NXP based ADV7186 eval board.

Can you please guide how to debug this issue?
