I noticed that meta-xilinx is still building linux-xlnx-3.14 kernel where as Petalinux-2015.2 is being shipped with linux-xlnx-3.19 kernel. I have ZC702 & Zedboard to boot the Xilinx SDKs, May I know which is the latest sdk for these boards ?

I am not sure what PetaLinux 2015.2 is based on or what it includes.
However meta-xilinx has nothing to do with PetaLinux, there is no implicit or explicit intention to track or match PetaLinux versions of anything. As for the kernels in meta-xilinx the linux-xlnx_3.14 kernel is based on the "xlnx_3.14" branch of the linux-xlnx repo. The linux-xlnx 3.19 kernel recipes in meta-xilinx are based on the "xilinx-v2015.2" tag of the linux-xlnx repo (aka the most recent release).

When you say "which is the latest sdk for these boards" what do you mean exactly?

I mean the release version. I saw the tag 2015.2, Are these the quarterly releases ?

As mentioned above the meta-xilinx layer has nothing to do with PetaLinux. However the plan is to continue to track the Xilinx kernel with recipes for updated releases of the Xilinx kernel.

PetaLinux is a separate product/toolkit that has little to nothing to do with the Yocto/OE tool flow. So the question you should really be answering is do you want to use Yocto/OE or PetaLinux?

Understood. I would really want to follow "Yocto/OE".

I don't see any reason why there wont be a 4.0 or newer release of linux-xlnx this year (either for the 2015.3 or 2015.4 release cycles), but I don't speak for Xilinx so you would need to confirm that is the case. But if you want to use a 4.0 linux-xlnx kernel right now, the master ref of the linux-xlnx repo is currently based on top of the 4.0 release. With the "linux-xlnx-dev" recipe in meta-xilinx you can use that kernel right now.

Sounds reasonable. Does 2015.2 (linux-3.19) supports Zedboard or just ZC702 only ?

Nathan

Thanks for your patience!
