Honored ContributorFinally the card came up..dont know why it shud have not programmed . except CONF_DONE , both nStatus and INIT_DONE were high when i measured using a multimeter. I tried probing CONF_DONE to see whether it goes high any time before/during/after configuration.It was low always.and the FPGA still dint get configured, though i got the error now even when all devices were in chain. again i dont know why this change happened. Next, i switched to probing nStatus and voila!!! it configured..!!:D I guess it provided some capacitance. I will be grateful if any one can explain this to me.
I was also unable to program the serial flash in the same powered state. i took out the card and re inserted it and it worked. no changes , no settings it needed. Sometimes electronics is so weird!!
