Hi, Suddenly the USB connection between my PC and Papilio one has stopped working. It was working for months and now the PC doesn’t recognize it and I cannot download code to the FPGA. The FPGA works fine because it has a previous code in its SPI flash that loads correctly when I plug the USB cable. My questions are whether it is the FTDI chip that is broken and if it is then is it possible to kill it with incorrect FPGA code? If my design eats more power than the USB port could supply could that also kill the FTDI chip? As my board is old and out of warranty shall I try to replace FTDI? Thanks Istvan
