SDK 8.0 using Beagle Bone White
I tried a very simple change to the /uboot/arch/dts/am335x-bone.dts
I made one change
I changed Model in am335x-bone.dts to TI AM335x DogStar BeagleBone(see uboot banner below) from what default was TI AM335x BeagleBone
My end goal is first modifying SPL then eventually uboot and changing ,dts files for a custom board based on Beagle bone design
For now I am using Beagle Bone White as a dev board
Very simple change I am off to a bad start I could use jtag to debug this but this has to be something basic I am missing in my understanding
