Power
I injected 5V on C60 (Fat ceramic cap , on top lower right corner near the sodimm edge)
The Module needs a fair ammount of current to start up properly. I had my lab supply at 3A current
limit, with the original config bitstream off the config prom on the module it draws about 700mA after startup
