This is a page about TI's BeagleBoard and BeagleBoard xM.



ARM Cross Compiler: GCC

This is a pre-built (32bit) version of Linaro GCC that runs on generic linux, so 64bit users need to make sure they have installed the 32bit libraries for their distribution. (ubuntu: ia32-libs)

wget -c
tar xJf gcc-linaro-arm-linux-gnueabihf-4.8-2013.06_linux.tar.xz
export CC=`pwd`/gcc-linaro-arm-linux-gnueabihf-4.8-2013.06_linux/bin/arm-linux-gnueabihf-

Bootloader: U-Boot

Das U-Boot -- the Universal Boot Loader


git clone git://
cd u-boot/
git checkout v2013.04 -b tmp



patch -p1 < 0001-omap3_beagle-uEnv.txt-bootz-n-fixes.patch

Configure and Build:

make ARCH=arm CROSS_COMPILE=${CC} distclean
make ARCH=arm CROSS_COMPILE=${CC} omap3_beagle_config

Linux Kernel

This script will build the kernel and modules and copy them to the deploy directory.

Old Board File tree


git clone git://
cd stable-kernel/

For v3.9.x:

git checkout origin/v3.9.x -b tmp

Checkout v3.11.x branch:

Setup microSD/SD card

For these instruction, we are assuming: DISK=/dev/mmcblk0, "lsblk" is very useful for determining the device id.

export DISK=/dev/mmcblk0

Erase microSD/SD card:

sudo dd if=/dev/zero of=${DISK} bs=1M count=16

Create Partition Layout:

sudo sfdisk --in-order --Linux --unit M ${DISK} <<-__EOF__

Format Partitions:

for: DISK=/dev/mmcblk0
sudo mkfs.vfat -F 16 ${DISK}p1 -n boot
sudo mkfs.ext4 ${DISK}p2 -L rootfs

for: DISK=/dev/sdX
sudo mkfs.vfat -F 16 ${DISK}1 -n boot
sudo mkfs.ext4 ${DISK}2 -L rootfs

Mount Partitions:

On some systems, these partitions may be auto-mounted...

sudo mkdir -p /media/boot/
sudo mkdir -p /media/rootfs/
for: DISK=/dev/mmcblk0
sudo mount ${DISK}p1 /media/boot/
sudo mount ${DISK}p2 /media/rootfs/
for: DISK=/dev/sdX
sudo mount ${DISK}1 /media/boot/
sudo mount ${DISK}2 /media/rootfs/

Install Bootloader

Copy MLO/u-boot.img to the boot partition

sudo cp -v ./u-boot/MLO /media/boot/
sudo cp -v ./u-boot/u-boot.img /media/boot/

uEnv.txt based bootscript

Create "uEnv.txt" boot script: (nano uEnv.txt)

#Camera: Uncomment to enable:

#SPI: enable for userspace spi access on expansion header

#LSR COM6L Adapter Board
#First production run has unprogramed eeprom:

#LSR COM6L Adapter Board + TiWi5

#These are now set by default: uncomment/change if you need something else

#mmcroot=/dev/mmcblk0p2 ro
#mmcrootfstype=ext4 rootwait fixrtc

Copy uEnv.txt to the boot partition:

sudo cp -v ./uEnv.txt /media/boot/
Unknown macro: {wiki}


No Ethernet:

  1. Check Power (aka use 5Volt DC Plug): The USB bus allows up to 100mA on initial connection and up to a max of 500mA can be requested by the end USB device. On the xM this is not enough to power the whole device and on the xM C there is an actual hardware switch to disable the smsc95xx usb hub/ethernet when powered by OTG (to prevent out of power crashes seen on the xM A/B with when users powered by OTG).
  2. Check Ethernet Cable/Plug: Is the Ethernet Cable actually plugged into the Beagle and Router?
  3. Check Modules: The smsc95xx kernel driver is usually built as an external module, double check that your kernel modules for this device are installed.
    debian@devel:~$ find /lib/modules/`uname -r`/kernel/ | grep smsc95xx
    debian@devel:~$ lsmod | grep smsc95xx
    smsc95xx               11302  0
  4. Reload smsc95xx kernel module (Checked all the above and the LAN LED's are still off)
    sudo rmmod smsc95xx
    sudo modprobe smsc95xx
    sudo /etc/init.d/networking restart
