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.

Qt Quick QML Digital Signage Demo Part 2

Following up on Qt Quick QML Digital Signage Demo Part 1, I’ve updated the digital signage demo to support the following: Play 5 videos in a loop Display 5 pictures in a loop where the picture is changed every 5 seconds Use a (twitter) RSS feed for the scrolling text I initially planned to use QML to list the media files, but it is apparently not possible without using C/C++ and I may do it later on. So instead, I hard-coded the video and picture playlists in the QML files with the ListModel element. Videos are located in the video directory and pictures in the pic folder. An index is needed to scroll thru the playlist, but QML does not support global variables, so I created a JavaScript file (globals.js) to store the video and picture index: // Global variables in JavaScript file var iVideoIndex = 0 var iPicIndex = […]
