This is my first time trying out DietPi and I ran into a problem booting my old Tinker Board (not S model). I did not see any mention of my problem anywhere, so I thought I would share the issue for others. That said, this might be a well know issue and I just missed the notes specific to my board.
Created a new SD image with DietPi_v6.25_ASUSTB-ARMv7-Buster.img. On first boot the image starts loading but the Tinker Board powers off before any video is generated. There are no power, network, or disk activity lights.
- Wipe SD card and re-write DietPi image (multiple SD cards tested): same failure
- Wipe and reload Volumio image: board boots up fine
- Replace USB adapter and USB cables multiple times: DietPi image continues to fail to boot
Can only boot the DietPi image by bypassing the USB power port. Using the GPIO ports (2&4: + 5.10V) (6: Power Ground) @ 1.80A I was able to boot the DietPi image.
I have not fully mapped the required voltage and amperage requirements. The board was not stable at 5V, 1.2A but seems rock solid at 5.1V, 1.8A.
I am running a REV. 1.2 Tinker Board.
I hope this information helps anyone else that might run into this issue. Please let me know if you would like any additional details and I will get you what I can.
