[meta-freescale] Error testing 3.10.9-1.0.0-alpha kernel [was Re: Request to integrate freescale i.mx 3.10.9-1.0.0 alpha release into dora branch of meta-fsl-arm]

Hi,

Sorry to ask again, did anyone manage to boot an i.MX6 Sabre board with the 3.10 kernel default configuration and device tree?

I am assuming no answer means no, but just in case.

Thanks,
Alex

Hi Otavio,

I could build core-image-minimal using master-next for the imx6qsabresd machine, forcing the 3.10.9 kernel.

Linux version 3.10.9-1.0.0_alpha+gdbf364b (alex at log-linux-hp-agonzal) (gcc version 4.8.1 (GCC) ) #1 SMP Tue Oct 22 17:16:38 CEST 2013

However, I hit the same GPU issue as I described before. Not surprising as the recipe is using the same sha1 as I was.

Also, I had to boot from a 2013.04 uboot. The 2013.10 uboot in master-next had problems booting the kernel. It got stuck in the " Starting kernel ...". I checked my environment and didn't find anything obvious, but I wouldn't rule out a misconfigured environment for that one.

Alex

Hello Alex,

Please don't mix thread. I am changing subject of this one...

I pushed current 'Work in Progress' 3.10.9 patches into master-next
and it'd be very helpful if you could give it a try.

I am finishing testing those and will send to the mailing list for
review. So your test would be more than welcome.
