T2080 custom board connection issues with codewarrior tap

I am working on a custom board with a t2080, have previously been able to successfully connect to the processor (read SPD and perform DDR validation process).

Beginning this week I am now unable to read SPD data and/or perform the DDR validation with codewarrior. Last week I was using the usb connection, this week I have attempted both the usb and ethernet connection.

 

Using ccs it always seems to fail on execution of ccs::reset_to_debug (appears to succeed when using the ethernet connection, but the board does not enter debug, I can still interact with the u-boot prompt).

When it doesn't work (using the usb) the board is reset and u-boot restarts, and ccs reports the core is not responding.

 

I have tried just about everything I can think of and could find online, without any luck.
