Setup microSD 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 card:

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 the Boot & Root File System Partitions:

Install Bootloaders:

Copy MLO to the boot partition

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

Copy u-boot.img to the boot partition

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

Create U-Boot "uEnv.txt" boot script: (nano uEnv.txt)

uEnv.txt
console=ttyO2,115200n8

#These are now set by default: uncomment/change if you need something else
#defaultdisplay=dvi
#dvimode=1280x720MR-16@60

optargs=console=tty0

mmc_load_image=fatload mmc 0:1 0x80300000 zImage
mmc_load_initrd=fatload mmc 0:1 0x81600000 initrd.img; setenv initrd_size ${filesize}

#Just: zImage
xyz_mmcboot=run mmc_load_image; echo Booting from mmc ...
loaduimage=run xyz_mmcboot; run deviceargs; run mmcargs; bootz 0x80300000

#zImage and initrd
#xyz_mmcboot=run mmc_load_image; run mmc_load_initrd; echo Booting from mmc ...
#loaduimage=run xyz_mmcboot; run deviceargs; run mmcargs; bootz 0x80300000 0x81600000:${initrd_size}

Copy uEnv.txt to the boot partition:

sudo cp -v ./uEnv.txt /media/boot/

Note: This repo tree is under active development, so the Kernel version can change on a daily basis...
Copy Kernel zImage:

sudo cp -v ./stable-kernel/deploy/3.6.6-x3.zImage /media/boot/zImage

Copy Kernel dtbs (v3.6.x++):

sudo mkdir -p /media/boot/dtbs/
sudo tar xfv ./stable-kernel/deploy/3.6.6-x3-dtbs.tar.gz -C /media/boot/dtbs/

Copy Root File System:

sudo tar xfvp ./*-*-minimal-arm*-*/armel-rootfs-*.tar -C /media/rootfs/

Copy Kernel modules:

sudo tar xfv ./stable-kernel/deploy/3.6.6-x3-modules.tar.gz -C /media/rootfs/

Tweak "/etc/fstab", the defaults should work for most boards:

sudo nano /media/rootfs/etc/fstab

Edit:

/etc/fstab
/dev/mmcblk0p2   /           auto   errors=remount-ro   0   1
/dev/mmcblk0p1   /boot/uboot auto   defaults            0   0
Enable Networking on Bootup:
  • Note: Boards without ethernet interfaces will have delays on bootup.
sudo nano /media/rootfs/etc/network/interfaces

From: (uncomment)

/etc/network/interfaces
#auto eth0
#iface eth0 inet dhcp

To:

/etc/network/interfaces
auto eth0
iface eth0 inet dhcp
Enable Serial Login:

Debian:

sudo nano /media/rootfs/etc/inittab

edit last line:

/etc/inittab
from: T2:23:respawn:/sbin/getty -L  115200 vt102
to: T2:23:respawn:/sbin/getty -L ttyO2 115200 vt102

Ubuntu:

sudo nano /media/rootfs/etc/init/serial.conf

Add:

/etc/init/serial.conf
start on stopped rc RUNLEVEL=[2345]
stop on runlevel [!2345]

respawn
exec /sbin/getty 115200 ttyO2

Remove microSD card:

sync
sudo umount /media/boot
sudo umount /media/rootfs

FAQ

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
    /lib/modules/3.2.26-x14/kernel/drivers/net/usb/smsc95xx.ko
    
    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
