You can find mirrors for the above downloads at beagleboard.org as well.

If you want to use the DSP, you need to add 'mem=99M@0x80000000 mem=128M@0x88000000' to bootargs for 256MB ram devices and 'mem=99M@0x80000000' for 128MB RAM device or 'mem=99M@0x80000000 mem=384M@0x88000000' for 512MB RAM devicess.
If you want to flash MLO and u-boot to NAND, these are the u-boot commands you need to use:
NOTE: in recent u-boot versions (e.g. 2008.10) the 'nand ecc' command has been renamed to 'nandecc', so without a space in between to compensate for that 'mmcinit' is now 'mmc init'
mmcinit
mmc init
mmc rescan 0
fatload mmc 0 82000000 MLO
nand unlock
nand ecc hw
nandecc hw
nand erase 0 80000
nand write 82000000 0 20000
nand write 82000000 20000 20000
nand write 82000000 40000 20000

To the Beagleboard Beginner

These short notes aim to help beginners get a working Angstrom system running on the beagleboard.

How to Unpack and Boot the Demo Image

  1. Format the SD card using mkcard.txt. For example: sh mkcard.txt /dev/sdX, where X is the drive letter of the SD card. On systems like Ubuntu that would look like 'sudo sh mkcard.txt /dev/sdX'.
  2. Copy MLO and u-boot.img from http://www.angstrom-distribution.org/demo/beagleboard/ to the first partition
  3. Unpack the tarball to the root partition of your Beagleboard SD card.
    NOTE: superuser privileges are required when unpacking the image so that device nodes can be created on the SD card filesystem.
    eg. for Linux:
    
      $ sudo tar -xjv -C /media/rootfs -f /path/to/Angstrom-Beagleboard-demo-image*rootfs.tar.bz2
    
    
    This assumes that the SD card has the root filesystem (ext3) partition mounted as /media/rootfs.
    NOTE: unpacking can take several minutes due to the amount of data.
  4. Ensure all SD card filesystem operations have completed (ie. filesystem cache has flushed to SD card) and eject the SD card from your development machine. Most operating systems have a "Safely Remove" action to perform this from the Desktop.
  5. Insert SD card into Beagleboard and power it up.

NOTE: Use external 5V supply and remove all USB connections from the Beagleboard when booting for the first time. Try USB later once you know it works.

What to Expect

Watch the serial port output. You should observe the following:

Some common problems and their fixes

The USER Button

The USER button on the beagleboard is your get-out-of-jail card. It allows reapir of a "bricked" beagleboard. If you break the software badly like writing a broken bootloader to NAND flash on the beagleboard, the USER button allows you to undo the mistake.

If you hold down the USER button at power on, the beagleboard will look for x-loader and boot loader code in the SD card instead of loading it from NAND flash. Under normal operation the the boot loader is located in NAND flash. In this normal case the kernel and filesystem still usually remain on the SD card.

Once the beagleboard has booted into the kernel, the USER button is just an input which can be used for any purpose you desire.
