Android 4.0 Hardware Graphics Acceleration Coming to More Platforms

The Linaro Android Platform Team has just posted a weekly update to their progress. They are going to release 11.12 very soon with hardware graphics acceleration to 2 of their members development boards: ST Ericsson Nova A9500 Snowball and Samsung Exynos 4212 Origen boards. So if you have any boards or products based on those processors you should be able to get an hardware optimized version very soon. Hardware acceleration is already available on all OMAP4 platform such as Pandaboard, since this was the default Android ICS target. They also introduced support for the ARM DS-5 debugger, an Eclipse plug-in to help developer create high performance performance and low power native software by integrating a graphical debugger for code generated for the Android Native Development Kit (NDK) and a basic version of the ARM Streamline performance analysis tool. Here’s a list of this week achievements: Key Points for wider discussion […]

Build the bootloaders (U-boot & X-Loader) for Pandaboard

I’ve tried to compile u-boot and x-loader for Pandaboard by following the instructions given at http://omappedia.org/wiki/Get_started_with_ubuntu_on_omap4#Bootloaders. I did this in Ubuntu 10.04 LTS with Linaro gcc compiler. Here are the instructions for the build: Create the folders:

mkdir bootloader
cd bootloader

1 2	mkdir bootloader cd bootloader

Get u-boot and checkout the omap4_dev branch:

git clone git://git.omapzoom.org/repo/u-boot.git
cd u-boot
git checkout L24.9

git clone git://git.omapzoom.org/repo/u-boot.git

cd u-boot

git checkout L24.9

You may use a different tag. Simply run “git tag -l | grep L24” to see the list of tags. (I used the latest at the time of this post). Build u-boot for OMAP4

make ARCH=arm distclean
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- omap4430sdp_config
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-

make ARCH=arm distclean

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- omap4430sdp_config

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-

At this point, you should get U-boot (u-boot.bin). get x-loader and checkout the omap4_dev branch:

cd ..
git clone git://git.omapzoom.org/repo/x-loader.git
cd x-loader
git checkout L24.9

cd ..

git clone git://git.omapzoom.org/repo/x-loader.git

cd x-loader

git checkout L24.9

N.B: Both u-boot and x-loader folders must be at the same directory level. build x-loader for OMAP4:

make ARCH=arm distclean
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- omap4430sdp_config
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- ift

make ARCH=arm distclean

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- omap4430sdp_config

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- ift

The x-loader (MLO) should now be ready. Finally, you simply need to copy MLO and u-boot.bin files to the SD card.
