BootingBeagleBoard
Procedure to boot Linux on Beagle Board.
Booting Beagle SoftwareBeagle Board can boot from NAND, MMC, UART, and USB. At present we support only NAND and MMC booting. The compilation steps for software components and pre-built images are described at Beagle Software Compilation Procedure Booting u-boot on Beagle BoardThe u-boot booting on NAND and MMC need another software component called x-loader. The booting procedure for x-loader as such doesn't need any detailed explanation, so this section includes x-loader booting as well. Booting u-boot on NAND Flash Texas Instruments X-Loader 1.41

Boot the Linux Image on Beagle BoardOnce you have u-boot booted over NAND or MMC, a Linux kernel image can be booted on Beagle Board. The Linux Kernel Image (uImage) can be downloaded on to Beagle DDR memory using UART (time consuming), MMC, NAND (if it was stored in it), USB (Not supported yet). The Below procedure gives MMC based Linux Kernel Booting.
OMAP3 beagleboard.org # mmcinit
OMAP3 beagleboard.org # fatload mmc 0 0x80300000 uImageThe filesystem to be mounted could be present in MMC, RAM (Ramdisk), NAND (if copied), Ethernet (using Ethernet over USB Dongle on USB HOST machine). The Bootargs for each of these is shown Below
OMAP3 beagleboard.org # setenv bootargs console=ttyS2,115200n8 ramdisk_size=8192 root=/dev/ram0 rw rootfstype=ext2 initrd=0x81600000,8M nohz=off OMAP3 beagleboard.org # setenv bootargs console=ttyS2,115200n8 noinitrd root=/dev/mmcblk0p1 rootfstype=ext2 rw rootdelay=1 nohz=off TBD TBD
OMAP3 beagleboard.org # fatload mmc 0 0x81600000 rd-ext2.bin
NOTE: rd-ext2.bin should have been copied onto MMC Card. Format an MMC/SD card for ext2/ext3 file system using Linux Machine
Mount the MMC/SD card on Host Linux Machine
UnTar the Pre-built Filesystem
Un-Mount the MMC/SD card on Host Linux MachineOMAP3 beagleboard.org # bootm 0x80300000 |

The two cases that need to be considered are: 1) the factory installed u-boot is running fine and 2) the NAND flash needs to be completely replaced back to factory conditions.
this page is linked to for the HP Boot tool, i found it here.

Hi, I have this problem.
kernel panic - not syncing: VFS:Unable to mount root fs ...
Can somebody suggest me, how to solve this.
Hi,
It worked, it mounted File system.
Just followed

since i used Ubuntu 8.04 LTS Geometry of SD card options was not working fine me. If you need any help on this pls let me know.
Bootargs for NAND (JFFS2) File System) TBD Bootargs for NFS (using Ethernet over USB Dongle) TBD
what it mean TBD
TBD means "to be done"

Wrong Image Format for bootm command ERROR: can't get kernel image! OMAP3 beagleboard.org #PROVIDE SOLUTION
biswajit.jun, Which version of u-boot do you use? I had same when I tried version on Angstrom demo files (it messes with bootup environment). Try older version like 1.3.3 - it works OK.
So I finally got the board speaking through hyperterminal. I however am having trouble getting it to recognize the SD card and boot with MMC? Anyone have any suggestions?
Hi, I have this issue wherein I get CRC verification failed when I do a bootm after copying the kernel image from SD to memory.. I tried 2-3 different images, but in vain. I tries the same image given for verification in google code.. pls advice... what are the possible reasons? The image is fully copied to memory... no problem there. Thanks, -Rajesh
Whats the best way to set up the fstab for a board booting from MMC?
I get a bunch of errors on startup, and I'm assuming they're from trying to mount the main filesystem as flash...
Guys, After creating the two partitions, I copied the files in the order specified on the beagleboard page, http://code.google.com/p/beagleboard/wiki/BeagleboardRevCValidation to partition labled W95 FAT32(LBA)
Disk /dev/sdb: 2032 MB, 2032664576 bytes 255 heads, 63 sectors/track, 247 cylinders Units = cylinders of 16065 512 = 8225280 bytes
Disk identifier: 0x112a1eb6
Command (m for help):
MLO u-boot.bin u-boot-f.bin ramdisk.gz uImage.bin boot.scr x-load.bin.ift normal.scr
The instructions did not specify what files go to the respective partitions. So, I copied everything onto the FAT32 partition.
I just cannot get the beagleboard(Rev B7) to boot from SD card.I do NOT know what else to try. This is frustrating. Please help.
Hi gurushunkara, I used the Angstrom files on a revision C3 boards and it worked quite well, so I suggest you try Angstrom first. You say "I just cannot get the beagleboard(Rev B7) to boot from SD card" - can you explain what happens when you boot?
Can other versions of Linux other than the Angstrom be run on the Beagle Board..I have to run matlab on the linux (this is the reason !) !
I'm in the same situation as gurushunkara. I have beagleboard Rev C3 with 2GB card. I have tried with 8GB and 1GB card. I just can't get it to boot from SD card. it starts up with beagle image, then beagle image is wiped away, but pawns are left. then board just hangs...
Please help!
try to copy "MLO u-boot.bin u-boot-f.bin ramdisk.gz uImage.bin boot.scr x-load.bin.ift normal.scr" files one by one on you mmc and rename it before copy one other file, and START by MLO file.
I have purchased a beagleboard. On powering it up using USB port (from Laptop) it keeps printing "Texas Instruments X-Loader ....." continuously. And no LED except POWER LED gets on.
But whe I use AC power then there is no output on console. But it seems that board is booting as after some time 3 LEDs get oned.
I am not sure whether its a hardware issue or what.
I used the files and followed the procedure from http://code.google.com/p/beagleboard/wiki/BeagleboardRevCValidation
I get following messages:

I also renamed the normal.scr as boot.scr and re-tried, it didn't continue further. Kindly help.
