Linux kernel trees don't match, even though they're supposedly the same version

Steve Ziuchkovski

I have two Linux kernel source trees, supposedly from the same version.

The first came from the AM335x SDK 07.00.00.00.

The second came from this git repo (specifically, the .tar.gz download link on the linked page). The linked page (I'm pretty certain) is where I got from following the release notes from the SDK version to the kernel version to the git repo branch/tag.

The problem is, the file "arch/arm/configs/tisdk_am335x-evm_defconfig" is present in the SDK tree but not in the git repo tree I took a snapshot of.

Why is this? Shouldn't the two be identical? Are there additional files added to the SDK linux tree that are not in the git repo kernel tree?

Hi Steve,

You need to be on ti-linux-3.12.y branch of ti-linux-kernel. Furthermore, you need to use omap2plus_defconfig when you pull down that repo. It's pretty much the same config as the tisdk_am335x-evm_defconfig.

If you follow the release notes, I'm on the right branch and right commit:

The SDK release notes for 07.00.00.00 link to Kernel release notes which specifically call out commit 2325bb5680986b6914d8fd0b5d0bdc20081fe8d3, which is the one I linked to in the original post above. Is this not the right commit?

Hi Steve,

Once you are at that commit, you also need to apply some patches which are included in our SDK. Once this is done, then the sources will be the same. The patches can be found in the following directory of the SDK:

ti-sdk-am437x-evm-07.00.00.00/board-support/linux-3.12.10-ti2013.12.00/patches

Also, omap2plus_defconfig is equivalent to tisdk_am335x-evm_defconfig.

Josh
