I'm using xc3sprog with the following command line when logged in as root to see if I have a connection:
From what I can see I'm getting activity on TMS (normally high, pulses low), TDI (normally high, pulses low), TDO (normally low, pulses high) and TCK (normally low, pulses high).xc3sprog -c sysfsgpio_creator -j
I've put debug statements into xc3sprog and it's just not reading anything, whether or not I have the connector on the TF536 or not.
I've quadruple checked the cable connections.
TMS: Pin 7
TCK: Pin 11
TDO: Pin 13
TDI: Pin 15
