Hi! Looks like the TDO pin of the CPLD, for whatever reason, is stuck at 0. I would check for bad soldering and other obvious things. Also make sure the emulation is not running while you try to update the CPLD.

I close this Issue, as its not a bug of PiStorm but rather a error on the PCB you have.
