I left my board connected to my laptop and power to the board was abruptly cut off when the laptop died. I tried to connect the board to a different computer and realized that it no longer turned on. The computer's device manager shows that something is plugged in, but Adept and Vivado are unable to recognize that a device is connected. I was planning to restore the board to it's default setting on Vivado by using a .bin file but received the following error message: "ERROR: [Labtools 27-2269] No devices detected on target localhost:3121/xilinx_tcf/Digilent/210292AA77E6A. Check cable connectivity and that the target board is powered up then use the disconnect_hw_server and connect_hw_server to re-register this hardware target. ERROR: [Common 17-39] 'open_hw_target' failed due to earlier err." I used a voltmeter to test the voltage across the on/off switch and was getting around 3.3V but now get 0.003V. When I tested the switches that control the on-board LEDS, the also produced around 0.003V. Is there a solution to help me with this as the board is brand new?
I am learning how to operate an FPGA, and I have to input a signal (which in itself is the output of a discriminator), and analyze it through a Basys3 FPGA. Looking at the available ports on the board, I'm guessing that it could be done using the Pmod ports, but even after hours of googling and going through the manuals, I failed to know which data ports to use, and how to read the signal after I've input it through the board. I've got references to some boards, in which GPIO ports are explicitly labelled, but I don't see any such labeling on the Basys3. So, it'd be really helpful if someone can provide me with any insight regarding this. Any other references or links would also be greatly appreciated. I've already gone through the basic tutorials (like lighting the led using the switch. I just want to know how to use the input ports, and analyze my signal. Thank You
