  1. Hello, I just opened my new basys3 board (novice EE student). As per the documentation I tried to power the board via usb-b (port j4) first through a laptop usb then through a 5v 2A charger making sure the jp2 jumper was set on usb and jp1 to the spi flash test program but the board did not turn on (not even the power good led). Trouble shooting that I performed: 1. Changed cable twice (didn't work) 2. Changed charger and usb ports (didn't work) 3. Powered board from external 5v power supply - the board worked perfectly. My question is could the smd soldering be defective, where can I mesure the voltage provided by the usb? Thank you for your help, If there is any more information I can provide please let me know
