11 years agoOK, then there might be some problem in my board, as even though I can upload configuration data to EPCS memory the FPGA doesn't configures itself and CONFIG_DONE pin
remains LOW after power-up ( while nSTATUS is High ). The voltage distribution on my board is as follows: VCCIO ( All Banks ) = 3.3V VCCA = 2.5V VCCINT = 1.2V So far I can only suspect some broken track on the board, as schematic and PCB layout are according to Fig 8-28.
