How to use yocto build for intel eds branch?

Hi,

How can i use eds branch in the yocto environment of intel edison.
The current recipee is using 3.10 kernel. I just replaced the git repository and the branch to use eds branch and it fails to build.
Is there a standard way how I should use this branch on yocto environment? If not, I will try to put my debug information here.

Thank you!

I would love to know that as well, thank you for your work @andy-shev.

I would try to understand how to do that in the future when I have free time slot. Never used Yocto before.

Hi!

This recipe is based on the latest official image sources. Unfortunately, Intel's configuration step is a small hack, but otherwise will work OK.

To use it:

  • Find the original linux-externalsrc.bb.
  • Replace its contents with the ones I've added below
  • In the do_configure change the meta-xxxx-xxxx to whatever is your location of the kernel recipe
  • Copy Andy's i386_defconfig to the files directory next to the recipe. I called it andy-defconfig, so either rename it, or change it in the do_configure

Warning

This will work when building the kernel only(bitbake linux-externalsrc). Unfortunately, building the whole image fails during the wi-fi kernel module compilation. Didn't really have much time to poke around with this.

Guys, can we move this issue to meta-acpi repository (I recently forked one)?
I dunno how to exactly move the issue, if someone knows, let me know.

Got an answer from tech support that there is no such feature. Please, reopen this bug in meta-acpi repository. I'm about to enable issue tracker there.

By the way @htot gets full build ready of Yocto based on latest and greatest vanilla kernel and U-Boot. Details are here: https://github.com/htot/meta-intel-edison/
