ERROR COMPILING KERNEL

[Héctor Chávez Santos]

I am trying to create an Android Kernel under AOSP build android-4.4.4_r2.

I followed the steps to download the source and build from these links for branch android-4.4.4_r2.

https://source.android.com/source/downloading.html

https://source.android.com/source/building.html

Everything ran OK.

Now I am trying to build a kernel as an example following the steps at:

https://source.android.com/source/building-kernels.html

The AOSP branch I downloaded doesn't have a "device/ti" directory, so I "mkdir device/ti" and in here I cloned:

git clone https://android.googlesource.com/device/ti/panda, generated path is "device/ti/panda".

The I "cd device/ti/panda" and ran "git log --max-count=1 kernel" which prints:

$ git log --max-count=1 kernel

    New PandaBoard kernel

    

    Built from kernel cb5fc502c60be9305c5a007be335e860d9e7c0cb

    

    cb5fc50 Revert "I2C: OMAP: correct SYSC register offset for OMAP4"

    623520a ARM:Panda: Add TI ST HCI flag

    582ab23 Bluetooth: Add tty HCI driver

    

    Change-Id: Ib3d6b2c809f0f88586455c4056f92511a845c70b

After this, I cloned inside "device/ti/panda":

git clone https://android.googlesource.com/kernel/omap.git

After this I "cd device/ti/panda/omap"

And inside "device/ti/panda/omap", I try to do a checkout with:

git checkout 224d695ed9e09c32479b63412eb345e78c2b4349

But this generates this error:

"fatal: reference is not a tree: 224d695ed9e09c32479b63412eb345e78c2b4349"

The checkout tag (224d695ed9e09c32479b63412eb345e78c2b4349) I used is what I get from the "git log --max-count=1 kernel" command

What is wrong in the procedure?

I have 2 days and cannot figure out what is wrong.

Please help!

Thank you.
