Variscite eval Board

Hi
I'm trying to test yocto on the VAR-SOM-Imx6 board from variscite.
I followed the tutorials and could easily build the fsl image but when
booting i get the following error from uboot:
Wrong image format for command boots
Could not find kernel

Is any one understanding this message? I'm really unfamiliar with uboot so
I might be missing something obvious, but I googled the error message,
parsed the mailing list, and could not find anything :(


Thanks,
J.

It'd be great if they could contribute official support to add it in
the meta-fsl-arm-extra :-D

It most probably needs change in U-Boot environment.

Is their kernel/u-boot available in any GIT tree I can take a look at?

Their wiki here http://www.variwiki.com/index.php?title=VAR-SOM-MX6_-_Linux_support#Building_U-Boot.C2.A0 
​Gives the directions to build uboot and the kernel but it seems to need "private" patches :(

Well once you buy a module with U-Boot they're obligated to provide
the source code as U-Boot is GPLv2. Once you get it, you can share it.

Without source code it is hard to know what  they're doing ;-)

Hi Otavio,

Would you happen to have some placeholder to recommend for me to put these patches ? I don't have a public git :(

Dropbox?

It'd be good if you could put your Variscite contact in the loop so
he/she knows you wish to use Yocto.

He knows about this discussion, but I'm not sure he's willing to be in the "loop" this way. I'll ask him

Why not simply add the support of this board to upstream U-boot?

We should avoid keep maintaining old versions of U-boot.

I'd love it but as I said its out of my skills area:( the initial thread was about asking why I couldn't boot and Otavio offered to have a look to Variscite's patch
I can't tell which policy Variscite will follow about their patches...

... but it seems easy to port. It'd be good if Variscite could support this.

But to get it working for you, it seems it must change environment only.

If we don't break their copyright it is all legal for us to use and
distribute this.

I'm sorry, that doesn't ring any bell in my head :( 
Is this some configuration tweaking or a change in u-boot code?

Sure, but I guess it'd be easier if they did it by themselves…


Anyway, thanks a lot !

Yes; you must adapt the default env to something like:

https://github.com/Freescale/u-boot-imx/blob/patches-2013.07/include/configs/wandboard.h#L112

Or sponsor someone to do it; that's why I asked you to put them in the
loop. They should be made aware of a customer wishing to use U-Boot
mainline and to have it supported in Yocto.
