DHT-Walnut -Debian Install

Jump to: navigation, search

This page contains information on installing Debian on the DHT-Walnut board.

uImage. contains a kernel and a ramdisk containing the Debian Netboot Installer. The installer will download a basic Debian System from the internet and install it to your hard disk. Your DHT-Walnut board must have internet access in order to use this installer.

Download uImage. and boot it on your walnut with commands similar to:

setenv bootargs console=ttyS0,115200 root=/dev/ram

tftpboot 1000000 uImage. bootm

If you are using a different console device or baudrate, please adjust the bootargs environment variable as required.

After the kernel boots, the Debian Installer will automatically begin and present a series of menus to proceed with the installation.

The Debian Installation Guide for PowerPC is available at

Since the Debian Installer image used here was not built specifically for the DHT-Walnut board or for the specific kernel being used, the following notes may be helpful.

  • The modules on the Installer image don't match the kernel, so you will see messages like

No kernel modules were found. This probably is due to a mismatch between the kernel used by this version of the installer and the kernel version available in the archive.

This is not a problem, since the needed modules are already built into the kernel.
When this question
 Continue the install without loading kernel modules?
appears, simply answer Yes
  • You may see a message like

Partition disks This partitioner doesn't have information about the default type of the partition tables on your architecture.

If so, answer Yes to this question:
 Continue with partitioning?
  • When partitioning the hard disk, create a small (large enough to hold any kernel image you would want to boot) partition for the kernel image.
  • I have only had success installing the stable (sarge) distribution. testing (etch) and unstable (sid) would not install for me. This isn't really a problem because you can easily upgrade distributions after installing the base system.
  • When the installer asks you to choose a kernel to install, simply choose one of the provided options. The kernel will be installed in /boot, but we will not use it with the DHT-Walnut board. Later, you may remove the /boot directory entirely if you wish.
  • Use the instructions in How to boot from hard disk to boot from the hard disk. Since in my system, /dev/hda1 contains my kernel image and partition 4 contains the Debian root (/) directory, I use the following commands to boot from the hard disk.

setenv bootargs console=ttyS0,115200 root=/dev/hda4 bootdisk 0:1
