When I built 12 current the other day, I found some confusing dtb file names. First there were identical files : am335x-bone.dtb beaglebone.dtb am335x-boneblack.dtb beaglebone-black.dtb But there was not a matching one for green. Is that intentional? am335x-bonegreen.dtb Then the content didn't match the names: am335x-boneblack.dtb -- compatible = "ti,am335x-bone-black", "ti,am335x-bone", "ti,am33xx"; am335x-bonegreen.dtb -- compatible = "ti,am335x-bone-green", "ti,am335x-bone-black", "ti,am335x-bone", "ti,am33xx"; Aren't the strings in the compatible line supposed to match the file names? Is there a reason there are identical files in the dtb path rather than a link? Is the fdt_file="" line required in loader.conf if the am335x file name exists? I have the BBB running with fdt_file="beaglebone-black.dtb", and the changes to it for turning on uart1. Should I have made the changes to the am335x file instead, or should I create the beaglebone-green.dtb file for the BBG? Tony
