Oh. I was wrong to trust Olimex naming of the dtb they ship, then. Some "nedko" at the "olimex irc channel hinted about dts files here: https://github.com/OLIMEX/DIY-LAPTOP/tree/master/SOFTWARE/A64-TERES/blobs This is out of my league - hope someone can make use of this. @Vagrant: You'd better remove my name as tester of a64-olinuxino dtb, as I don't (yet) own such hardware - only what might become named a64-teres. - Jonas -- * Jonas Smedegaard - idealist & Internet-arkitekt * Tlf.: +45 40843136 Website: http://dr.jones.dk/ [x] quote me freely [ ] ask before reusing [ ] keep private
