Building edison-image BSP with Linux 3.19.x #2
Description
This issues is to document my attempt to a build of linux kernel 3.19 to build as a yocto linux BSP layer on top of the Intel Edison BSP layer.
The intel/maker/edison forum post for this is at https://communities.intel.com/message/272467#272467
Edison - Software Downloads includes http://downloadmirror.intel.com/24389/eng/edison-image-rel1-maint-rel1-ww42-14.zip
Which I imported into github: https://github.com/instantinfrastructure/edison-src
and is the src of this github repo.
The recipe we need to override is here:
./device-software/meta-edison/recipes-kernel/linux/linux-yocto_3.10.bbappend
I haven't found any working examples of layers that build against 3.19.x?
I did find a layer that does not change the kernel version at richards-tech/meta-edison-rt

It looks like out of the box 3.17 is the highest integrated into the yocto / poky distribution builder... http://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/recipes-kernel/linux/linux-yocto_3.17.bb

linux-yocto-contrib seems to be getting the 3.19 stream http://git.yoctoproject.org/cgit/cgit.cgi/linux-yocto-contrib/log/
I just hope enough of the intel-mid stuff has been merged at this point!

I'm a bit worried that the platform/intel-mid is hugely different between 3.10.17 (with the intel patches) and what is in 3.19.0-rc4.... I'm going to wait until I hear something from the platform/intel-mid folks before I head down this route to far

From http://layers.openembedded.org/layerindex/branch/master/layer/meta-intel/
Official layer for Intel platform/board support. This layer itself (at the top level) contains common components, and then there are sub-layers for each BSP which are listed individually in this index.

However I don't see any kernel stuff on there...

@nitinkamble do you know where the edison bsp community repos are? I've gotten very little public information out of Intel, and this seems to be the correct external location but I don't find the word edison in any of these sources.

It look like the kernel configuration and source for many embedded devices don't get updated often. if we want the latest gadgets on devices like the Edison and Raspberry Pi, we are going to have to backport.
I'm interested in the bold ones.

This gave me the idea to retarget the first port to a raspi, at they have a 3.18 kernel
http://wiki.openmoko.org/wiki/Building_Gadget_USB_Module gave me an idea of how to build it as a module out of tree... sort of out of tree.

I see there's a 3.19.5 branch in the edison-linux repo: https://github.com/01org/edison-linux/tree/edison-3.19.5 ... not sure if it's stable

@pklapperich
Vanilla kernel (v4.11-rc1) supports most of the important parts of Edison out-of-the-box.

Nice! Thanks for the info @andy-shev !
andy-shev commentedon Mar 7, 2017
v4.11-rc1 is
a bit unstable (looks like a boot time regression bug that makes watchdog fired at boot time). I pushed back my v.4.10 based branch for Edison which works nicelystable now.
