    How are you progressing with this problem? I ask as it has been a while since you posted the question.

    It should be possible to make one JTAG scan chain. The TCK and TMS signals run in parallel to each device, while the TDI and TDO signals daisy chain from one device to the next. See this JTAG link on Wikipedia.
