    Dear Aiman,

    Sorry for the delay.

    I can compile and download the design to the one remaining board without issue, and have done so many times.

    I am measuring TCK actually on the PCB - PIN1 of the 10 pin header.

    The actual voltage does depend on the type of USB Blaster used - USB Blaster 2 gets to about 0.7V but others are slightly lower.

    Many thanks,

    Adrian
