Can't get the Cu to work... - Gleekzorp - 03-19-2022 Hi all, A question from an FPGA newbie: I bought a Cu, installed Alchitry Labs & IceCube2,and configured Labs so it knows where IceCube2 and the license file are located. Plugging in the Cu gives me a short flash of the 'Done' LED; voltage on the test points is 4.7V) I can building sample projects (HelloWorld, Led to Button) without any errors, same for flashing the Cu, but: no happ flashing LEDs of any kind... Any hints/tips/...? Am I missing something? Thanks in advance for any info! RE: Can't get the Cu to work... - alchitry - 04-15-2022 Do you get the DONE LED to turn on? Did your board show the test pattern when you first got it? RE: Can't get the Cu to work... - Gleekzorp - 04-15-2022 Hi Admin, thanks for your reply! No, the DONE led only gives a brief flash on power on, but that is the only activity observed; the board didn't show any kind of test pattern... Best regards, Gleekzorp
