AM6442: XJTAG connectivity

Part Number: AM6442

Hi Team,

We are facing an issue with XJTAG connectivity on our custom board which is AM6442-based board.

XJTAG is working fine on the TMDS64 EVM,However, on our custom board, XJTAG is not working.

We have followed the EVM design reference for JTAG connections, except we have not added a buffer in the JTAG signal path

Additionally ,XDS200 debugger is working fine on the same custom board

Could you please help us identify the possible cause of this issue? Can the JTAG buffer affect XJTAG operation?

Thanks,

Rubigaa
