Direzione di ricerca

Inizia con i passaggi di compilazione del kernel della wiki, quindi esamina /boot/uEnv.txt, i percorsi di am335x-bone.dts e dtbs e l’output di U-Boot che mostra il caricamento di device-tree e overlay. Documenta la sequenza completa di installazione di BeagleBone Black, inclusi i file e i percorsi richiesti; il lavoro è completo quando un nuovo arrivato può seguirla fino a un boot riuscito.

Descrizione

I managed to build a kernel using the steps in the wiki. I then copied the kernel, updated the uEnv.txt and put the am335x-bone.dts in the dts folder but when I rebooted it started complaining about some other device trees for uboot and it never loads.

What am I missing? Is there any step by step instructions for putting the kernel on the Black
