[meta-intel] SoC x1021 support in Intel-quark BSP

[Fredrik Östergren]

Hi Jussi,

Yes indeed it has grub on the SPI flash, I will give your suggestions a go and see if it works. It would be really good to get yocto running at the device.

Thanks for your help!

Best regards
Fredrik

Is this one of the boards that has GRUB 0.99 on the SPI flash?

If so, you can try to take the boot partition from the original
WindRiver card and just sign the kernel and initrd you've built with
signing tools and place those on the boot partition (FAT). Rootfs should
be fine. AFAIK, meta-intel doesn't support building images for such
boards (Intel DK100 and the likes).

WindRiver has tools for building images for those, though.

Hi again,

i tested the image, dd'd it to my sd-card, verified that I got two Linux-partitions at it and then tried to boot it but I still get error:

Error 37: Quark signature file not found

And then he open the recovery shell for grub

Thanks for your help!

Best regards
Fredrik

Hi,

We are testing a Supermicro SYS-E100-8Q board with an Intel Quark SoC
x1021 CPU for our IoT implementation and I was wondering if the BSP
"Intel Common core (intel-quark)" supports this processor?

It should support this, if you use the meta-intel layer and set
MACHINE=intel-quark.

Which version of the Yocto Project are you using?

If it does, what is the correct way to build the partition structure
and put the yocto image onto a SD card for booting this device ?

You can use the "wic" command and the mkgalileodisk.wks (or possibly
galileodisk-sd.wks) to correctly create a partitioned image that can be
dd'ed to an SD card.

Sau!

Thank you for your patience and help,

Best Regards
Fredrik
