What's the setup for this ?

I haven't changed anything on 4.14 that could trigger this. Has this been hidden, or really just start happening out of nowhere ?

Pristine checkout of current master:

It's not wrong: the 4.14 bbappend doesn't have any entries for beaglebone-yocto (or anything but genericx86).

I'll provision one of my builders for lsb and have a look.

Having a look at this more closely, it is rather obvious.

I tweaked the preferred version to 4.14 for lsb, but the h/w reference BSPs haven't been updated to match.

So I can either downgrade poky-lsb to 4.12, or we can see if Kexin can bump the reference boards.

He's been sending patches for the fsl board on 4.14/15, so I assume that that work is underway.

Kevin, I assigned this to you, so you can update the case on the progress of the h/w references to 4.14.

If it isn't going to happen (the update), assign it to me, and I'll just move the lsb preferred version to 4.12.

The mpc8315e-rdb doesn't boot without the patches I sent your several days ago. I have saw these patches merged in the linux-yocto git tree. But I know you would send the SRCREV update patch soon, so I would prefer to bump these hardware BSPs after your official SRCREV update.

Fixed in sumo.
