ARM Cross Compiler: GCC
This is a 32bit x86 application, so 64bit users will need to also install the 32bit libraries for their distribution. (ubuntu: ia32-libs)

Setup microSD/SD card
For these instruction, we are assuming: DISK=/dev/mmcblk0, "sudo fdisk -l" is useful for determining the device id..
export DISK=/dev/mmcblk0
Erase microSD/SD card:
sudo dd if=/dev/zero of=${DISK} bs=1024 count=1024 sudo parted --script ${DISK} mklabel msdos
Setup Boot Partition:
sudo fdisk ${DISK} << __EOF__ n p 1 +64M t e p w __EOF__
Set Boot Flag
sudo parted --script ${DISK} set 1 boot on
Format Boot Partition as vfat:
DISK=/dev/mmcblk0 sudo mkfs.vfat -F 16 ${DISK}p1 -n boot (or) DISK=/dev/sdX sudo mkfs.vfat -F 16 ${DISK}1 -n boot
Setup Root File System Partition:
sudo fdisk ${DISK} << __EOF__ n p 2 w __EOF__
Format rootfs as ext4:
DISK=/dev/mmcblk0 sudo mkfs.ext4 ${DISK}p2 -L rootfs (or) DISK=/dev/sdX sudo mkfs.ext4 ${DISK}2 -L rootfs
Mount Partitions:
Note: On most systems these partitions will be auto-mounted...
sudo mkdir -p /media/boot/ sudo mkdir -p /media/rootfs/ DISK=/dev/mmcblk0 sudo mount ${DISK}p1 /media/boot/ sudo mount ${DISK}p2 /media/rootfs/ (or) DISK=/dev/sdX sudo mount ${DISK}1 /media/boot/ sudo mount ${DISK}2 /media/rootfs/
Install Bootloaders:
Copy MLO/u-boot.img to the boot partition
sudo cp -v ./u-boot/MLO /media/boot/ sudo cp -v ./u-boot/u-boot.img /media/boot/
U-Boot user enviroment variables: uEnv.txt
Create U-Boot "uEnv.txt" boot script: (nano uEnv.txt)
#Camera: Uncomment to enable: #http://shop.leopardimaging.com/product.sc?productId=17 #camera=li5m03 #SPI: enable for userspace spi access on expansion header #buddy=spidev #LSR COM6L Adapter Board #http://eewiki.net/display/linuxonarm/LSR+COM6L+Adapter+Board #First production run has unprogramed eeprom: #buddy=lsr-com6l-adpt #LSR COM6L Adapter Board + TiWi5 #wl12xx_clk=wl12xx_26mhz #These are now set by default: uncomment/change if you need something else #defaultdisplay=dvi #dvimode=1280x720MR-16@60 #mmcroot=/dev/mmcblk0p2 ro #mmcrootfstype=ext4 rootwait fixrtc
Copy uEnv.txt to the boot partition:
sudo cp -v ./uEnv.txt /media/boot/
Install Kernel and Root File System:
To help new users, since the kernel version can change on a daily basis. The kernel building scripts in this git repo will now give you a hint of what kernel version was built.
----------------------------- Script Complete eewiki.net: [user@localhost:~$ export kernel_version=3.X.Y-Z] -----------------------------
Copy and Paste that "export kernel_version=3.X.Y-Z" exactly as shown in your own build/desktop environment:
export kernel_version=3.X.Y-Z
Copy Kernel zImage:
sudo cp -v ./stable-kernel/deploy/${kernel_version}.zImage /media/boot/zImage
Copy Kernel dtbs (Device Tree):
sudo mkdir -p /media/boot/dtbs/ sudo tar xofv ./stable-kernel/deploy/${kernel_version}-dtbs.tar.gz -C /media/boot/dtbs/
Copy Root File System:
sudo tar xfvp ./*-*-minimal-arm*-*/arm*-rootfs-*.tar -C /media/rootfs/
Copy Kernel modules:
sudo tar xfv ./stable-kernel/deploy/${kernel_version}-modules.tar.gz -C /media/rootfs/
Setup /etc/fstab:
sudo nano /media/rootfs/etc/fstab
Add:
/dev/mmcblk0p2 / auto errors=remount-ro 0 1 /dev/mmcblk0p1 /boot/uboot auto defaults 0 0
Enable Networking:
sudo nano /media/rootfs/etc/network/interfaces
Add:
auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp
Enable Serial Login:
Debian:
sudo nano /media/rootfs/etc/inittab
Add at end of file:
T2:23:respawn:/sbin/getty -L ttyO2 115200 vt102
Ubuntu:
sudo nano /media/rootfs/etc/init/serial.conf
Add:
start on stopped rc RUNLEVEL=[2345] stop on runlevel [!2345] respawn exec /sbin/getty 115200 ttyO2
Remove microSD/SD card:
sync sudo umount /media/boot sudo umount /media/rootfs
FAQ
No Ethernet:
- Check Power (aka use 5Volt DC Plug): The USB bus allows up to 100mA on initial connection and up to a max of 500mA can be requested by the end USB device. On the xM this is not enough to power the whole device and on the xM C there is an actual hardware switch to disable the smsc95xx usb hub/ethernet when powered by OTG (to prevent out of power crashes seen on the xM A/B with when users powered by OTG).
- Check Ethernet Cable/Plug: Is the Ethernet Cable actually plugged into the Beagle and Router?
- Check Modules: The smsc95xx kernel driver is usually built as an external module, double check that your kernel modules for this device are installed.
debian@devel:~$ find /lib/modules/`uname -r`/kernel/ | grep smsc95xx /lib/modules/3.2.26-x14/kernel/drivers/net/usb/smsc95xx.ko
debian@devel:~$ lsmod | grep smsc95xx smsc95xx 11302 0
- 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
