Problem Title:
Hardware Debugger: Configuring FPGA with Parallel Cable fails, Serial Cable works.
Problem Description:
Urgency: Standard
General Description:
Configuring an FPGA from the Hardware Debugger with the Parallel Cable III (JTAG cable) fails either
with the message: "Done pin doesn't go High" or by reporting that "The Device is configured" but th
e FPGA doesn't function.
This is because the PROG pin on Parallel cable III a.k.a. JTAG cable is held low after downloading t
hus forcing the device back to configuration mode.
Solution 1:
A workaround was to leave the Flying Lead Labelled PROG unconnected from the target device.
This problem has now been fixed in the software and a
patch is available at:
