Hi there

Hope this message finds you all well!

I really need your help, Just bought a BB Black with 4dSystems Cape GEN4-4DCAPE-70CT-CLB, but after a week trying I just can’t make it work. Can someone point me to the right direction?

Changed uEnv to boot the cape overlay but then the BB no longer boots.

Tried to use other overlays but or it doesn’t boot or it simple doesn’t work. Not even the backlight comes on.

Thanks

You shouldn’t need that… Can you please show:

sudo beagle-version

I’ll dig around for that lcd tonight..
