I just purchased a Sweet Potato from the storefront and received it a few days ago. I flashed a Sandisk 256GB with DD using the debian-12-base-arm64+aml-s905x-cc.img and at first it would give me a red light, steady blue light and a steady yellow light and nothing after a long time; no video either. I reflashed it several times and I think after the fourth time it booted and I finally got video (regrettably didn’t pay attention to the lights) and got the login prompt. I let it sit for a few hours and I unplugged it to move it to where I was going to permanently place it. Using the same power adapter (Anker 100w with an Apple USB-C to USB-C cord) but a different HDMI source, I plugged it in and got the steady red, blue, and yellow with no video again. After waiting a good 10 minutes and seeing the LEDs on my USB keyboard were not lit up, I unplugged it, waited about 30 seconds, and replugged it in. Still nothing; just a steady red, blue, and yellow lights and no video. I reflashed the SD card with DD and same thing.
I went to my Mac and used BelenaEtcher and the same img file and still got the same thing. When attached to my Linux machine, the SD shows a name of root and files and folders on it. Mac can’t read it worth a flip but Disk Utility shows 2 partitions, disk6s1 and disk6s2, with s1 being blue and a size 267.4MB and s2 red and a size of 2.15GB.
I am at a loss. As I said I only got it to boot once and I think it was just luck. Warning: I know enough about Linux to be dangerous: still learning. I do have a windows VM on the Mac, but haven’t looked at the SD on that. Any suggestions?
