I used the Raspberry Pi Foundation's Imager for the Raspberry Pi on MacOS. I successfully flashed ubuntu core 20.04.1 and put the card into the pi. At first, it showed the ubuntu logo with 'Core' for a few seconds and showed the blinking cursor on the top left. It showed that for ten minutes but nothing changed. (Also during this process, both LEDs were blinking like crazy)
I unplugged it and plugged it back in and now it won't even show up at all. Did I break something?
I'm using a Raspberry Pi 3 Model B with 1GB RAM.
