6.1.2 PandaBoard Software

Note: Only up to revision B2 of the PandaBoard are officially supported
The HDMI connector is the default display output of PandaBoard. To reroute the display video output to
the RGB interface of the DLP LightCrafter 4500, the kenrel config file must be modified with the following
changes:
• Disable DRM
• Enable DVI output
• Enable frame buffer support
To perform these changes, obtain the Ubuntu
• git clone git://kernel.ubuntu.com/ubuntu/ubuntu-precise.git
• git checkout -b working origin/ti-omap4
Install ARM compilers on Linux
• sudo apt-get install gcc-arm-linux-gnueabihf cpp-arm-linux-gnueabihf
• sudo apt-get install gcc-arm-linux-gnueabi cpp-arm-linux-gnueabi
To run the menuconfig, install ncurses package:
• sudo apt-get install build-essential ncurses-dev
Before compiling the Ubuntu kernel, the DVI port must be enabled. Run menuconfig:
• cp debian.ti-omap4/config/config.common.ubuntu.config
• sudo make ARCH=arm menuconfig
Select the following:
• Disable DRM under: Device Drivers → Graphics Support → Direct Rendering Manager
• Enable DVI under: Device Drivers → Graphic Support → OMAP2+ Display Subsystem support →
OMAP2/3 Display Device Drivers → DVI Output
• Enable frame buffer support: Device Drivers → Graphic Support → OMAP2+ Display Subsystem
support → OMAP2+ frame buffer support
Build the kernel:
• ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make
Generate the uImage:
• ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make uImage
The generated uImage will be located at ubuntu-precise/arch/arm/boot/uImage.
