New ContributorProcess of Programming Kills FPGA
We have had some instances where programming an FPGA appears to kill the FPGA.
For instance, we had two boards that has a Cyclone III and wouldn't program because Quartus said it couldn't access th...

New ContributorHi Bruce,
This is a custom board that one of our customers designed and initially tested. We manufacture, program and test these units. Then ship them finished units. We have been making these for years and have come across this problem in the past but haven't had a chance to look into it until recently. We still have plenty of success but want to increase the yield.
We only have one image to put on the FPGA and when I tried Quartus told me that it couldn't access the JTAG chain. So I wasn't able to load the image and the FPGA does nothing.
Thanks!
