Texas Instruments Beagleboard (beagleboard)
|
||||
===========================================
|
||||
|
||||
The Beagleboard is an ARM Cortex-A8 development board with USB, DVI-D, S-Video,
|
||||
2D/3D accelerated graphics, audio, serial, JTAG, and SD/MMC. The xM adds a
|
||||
faster CPU, more RAM, an ethernet port, more USB ports, microSD, and removes
|
||||
the NAND flash. The beagleboard MACHINE is tested on the following platforms:
|
||||
|
||||
o Beagleboard C4
|
||||
o Beagleboard xM rev A & B
|
||||
|
||||
The Beagleboard C4 has NAND, while the xM does not. For the sake of simplicity,
|
||||
these instructions assume you have erased the NAND on the C4 so its boot
|
||||
behavior matches that of the xM. To do this, issue the following commands from
|
||||
the u-boot prompt (note that the unlock may be unecessary depending on the
|
||||
version of u-boot installed on your board and only one of the erase commands
|
||||
will succeed):
|
||||
|
||||
# nand unlock
|
||||
# nand erase
|
||||
# nand erase.chip
|
||||
|
||||
To further tailor these instructions for your board, please refer to the
|
||||
documentation at http://www.beagleboard.org.
|
||||
|
||||
From a Linux system with access to the image files perform the following steps
|
||||
as root, replacing mmcblk0* with the SD card device on your machine (such as sdc
|
||||
if used via a usb card reader):
|
||||
|
||||
1. Partition and format an SD card:
|
||||
# fdisk -lu /dev/mmcblk0
|
||||
|
||||
Disk /dev/mmcblk0: 3951 MB, 3951034368 bytes
|
||||
255 heads, 63 sectors/track, 480 cylinders, total 7716864 sectors
|
||||
Units = sectors of 1 * 512 = 512 bytes
|
||||
|
||||
Device Boot Start End Blocks Id System
|
||||
/dev/mmcblk0p1 * 63 144584 72261 c Win95 FAT32 (LBA)
|
||||
/dev/mmcblk0p2 144585 465884 160650 83 Linux
|
||||
|
||||
# mkfs.vfat -F 16 -n "boot" /dev/mmcblk0p1
|
||||
# mke2fs -j -L "root" /dev/mmcblk0p2
|
||||
|
||||
The following assumes the SD card partition 1 and 2 are mounted at
|
||||
/media/boot and /media/root respectively. Removing the card and reinserting
|
||||
it will do just that on most modern Linux desktop environments.
|
||||
|
||||
The files referenced below are made available after the build in
|
||||
build/tmp/deploy/images.
|
||||
|
||||
2. Install the boot loaders
|
||||
# cp MLO-beagleboard /media/boot/MLO
|
||||
# cp u-boot-beagleboard.bin /media/boot/u-boot.bin
|
||||
|
||||
3. Install the root filesystem
|
||||
# tar x -C /media/root -f core-image-$IMAGE_TYPE-beagleboard.tar.bz2
|
||||
# tar x -C /media/root -f modules-$KERNEL_VERSION-beagleboard.tgz
|
||||
|
||||
4. Install the kernel uImage
|
||||
# cp uImage-beagleboard.bin /media/boot/uImage
|
||||
|
||||
5. Prepare a u-boot script to simplify the boot process
|
||||
The Beagleboard can be made to boot at this point from the u-boot command
|
||||
shell. To automate this process, generate a user.scr script as follows.
|
||||
|
||||
Install uboot-mkimage (from uboot-mkimage on Ubuntu or uboot-tools on Fedora).
|
||||
|
||||
Prepare a script config:
|
||||
|
||||
# (cat << EOF
|
||||
setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000'
|
||||
setenv bootargs 'console=tty0 console=ttyO2,115200n8 root=/dev/mmcblk0p2 rootwait rootfstype=ext3 ro'
|
||||
boot
|
||||
EOF
|
||||
) > serial-boot.cmd
|
||||
# mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Core Minimal" -d ./serial-boot.cmd ./boot.scr
|
||||
# cp boot.scr /media/boot
|
||||
|
||||
6. Unmount the SD partitions, insert the SD card into the Beagleboard, and
|
||||
boot the Beagleboard
|
||||
|
||||
Note: As of the 2.6.37 linux-yocto kernel recipe, the Beagleboard uses the
|
||||
OMAP_SERIAL device (ttyO2). If you are using an older kernel, such as the
|
||||
2.6.34 linux-yocto-stable, be sure to replace ttyO2 with ttyS2 above. You
|
||||
should also override the machine SERIAL_CONSOLE in your local.conf in
|
||||
order to setup the getty on the serial line:
|
||||
|
||||
SERIAL_CONSOLE_beagleboard = "115200 ttyS2"

||||
