Kernel & Driver Sources

Apply these patches on top of the release's kernel base commit-id.

git checkout 6925ea33846858fb0bcd427912a9508b79c0bac3
git am -3 <path-to-extracted-gzip-folder>/patches/kernel/*.patch

0001-panda_defconfig-Build-WLAN-as-module.patch
0002-panda_defconfig-Enable-V4L2-and-USB-UVC-camera.patch

Build Instructions

Building U-BOOT

Don't build it. Use the prebuilt binary included in the repo:

device/ti/panda/bootloader.bin

Which get's flashed through fastboot in a step below.

Building X-LOADER

Don't build it. Use the prebuilt binary included in the repo:

device/ti/panda/xloader.bin

Which get's flashed through fastboot in a step below.

Building Kernel

Use:

make ARCH=arm panda_defconfig

And after building the kernel, do:

cp arch/arm/boot/zImage ${MYDROID}/device/ti/panda/kernel

so it gets used in the .img generation.

Building Android Filesystem (AFS) with TI Codecs enabled

Use:

lunch full_panda-eng

And build with:

# For host with 4 CPUs:
make CC=gcc-4.4 CXX=g++-4.4 -j4

Preparing target

Follow file "${MYDROID}/device/ti/panda/README", to prepare your board.

Feel free to share corrections/suggestions about this procedure, so it can be improved.
