content: Hi,Finlay my first run PCB's came from china and I managed to solder the GW2AR-LV18QN88C8/I7 and test the chip the first blinky! every thing is working as expected, also I have connected pin 56 and 57 of the FPGA to some IO that I need, but the place and route complains about the current location is useless!is there any workaround this or I am stuck to redesign the PCB!
