Hi All,

I have just used Yocto with the meta-ti layer to build the minimal image, placed all the files on an SD card and tried to boot ..

It gets a couple of seconds into the kernel and hangs on mmc pin setting, copy of the boot --> http://pastebin.com/0asaJ9tf

Question: I built for MACHINE=beaglebone but I don't know if that is for the while or black targets, or if there is a difference.

I suspect the issue is with the device-tree file .. the tool built a file called uImage-am335x-bone.dtb, but when the kernel tried to boot, it wanted a file called am335x-boneblack.dtb, so I just re-named the produced file to that and I got the above boot sequence ..

Hi Bernie,

I did the same kind of build recently (10/15days ago, can't remember), and it worked like a charm, the same build (and images) can be used on all am335x boards (EVM, BB black/white, etc, but I tested only with the EVM and the BB black).

Basically, the bootloader detect the board it is running on and select the right DTB for you, cute! ;)
This imply that all DTB files have been installed on /boot of course, but you only need one MLO, u-boot and linux image.

Didn't try again since then.

My 2 cents, Chris.

Maybe that is the wrong thing to do? Is there a way to get the build to produce the am335x-boneblack.dtb file?

Thanks,

Bernie
