Problem porting the JBC Player in an Embedded System

I ported the JBC player (Jam STAPL ByteCode Player Version 2.2) for In System Programming per AN 122. When I attempt to read the ID code using the READ_IDCODE action, I get the following error

Device# 1 unable to read IDCODE

Unrecognized device

Exit code = 6... Unrecognized device.

I have scoped the TCK, TDO and TMS lines and there is activity on those pins.

Is there something I can do to debug this issue?
