I have managed to boot from TTL as follows:
- enter recovery mode (hold recovery and restart board by resetting)
- download upgrade tool, and official Ubuntu image, and run:
sudo ./Linux_Upgrade_Tool_v1.2/upgrade_tool uf Firefly-RK3288_Ubuntu14.04_201607222032.img
This burns the image to the eMMC.
- that image works. From inside of it, clear eMMC to ensure that it will not be used instead of the SD: sudo dd if=/dev/zero of=/dev/mmblk0
- try again
However I can't get HDMI / VGA output to my screen, only TTL access.
I also tried to insert the cable after boot, but it did not help. |
