[Android Stick & Console AMLogic based Computers] chrismin13:
Hey all, sorry for a bit of a necro.

Has anyone managed to interrupt u-boot on the latest firmware (currently Feb 2021 update)? I already tried Ctrl-C, Enter and Space. There seems to be no way to enter the uboot terminal. I would like to run ambian on my device, as it lacks the DRM keys and is pretty useless now that it's not a chromecast and can't play Netflix.

This is my boot log:

If anyone has any ideas on what I could do with this device to make it a little more useful, let me know!

Thanks :)
