I am trying to use my Le Potato board to run Raspbian. I have installed the official version from the LIbre Computer Board Website, and used the Raspberry Pi Imager application to flash the libre raspbian img file onto an SD card. However, when I try to power on my board, the red and blue light stay on but the green light never turns on. Nothing appears when I connect an HDMI cable as well. I have tried multiple SD cards and none have worked. This board also previously worked fine when I had Ubuntu 22.04 installed on it. What to do?
