port to PPC 403

[Jason Adams]

is there a kernel out there that i can use to boot my IBM netstation
(model 8361-110 with a PPC 403 chip)

thank you

Jason,

The Linux port to the PowerPC 4xx family isn't quite* that far along yet.
The latest status on the 4xx port is available at:

Non NFS boot

[Hans - Dulimarta]

A few weeks ago, there were discusions on linuxppc embedded kernel which
is able to boot in NFS root mode.

I'm looking for information on a similar kind of kernel which does not
require NFS root.

Sure. Here's a section from a brief LinuxPPC Embedded HOWTO I've been working
on which may get you started: (feedback from all is welcome)

Root File System

Minimal and complete root file system images are available on the ftp site at:
ftp://linuxppc.cs.nmt.edu/pub/linuxppc/embedded/mbxroot.min.tgz and
ftp://linuxppc.cs.nmt.edu/pub/linuxppc/embedded/mbxroot.full.tgz

During development, the embedded system can NFS-mount its root file system to
provide a complete diskless Linux system. Answer "Y" to the configuration
questions regarding NFS client and root filesystem via NFS, and "make zImage".

To make your system standalone, you need an initial ramdisk image containing
an ext2 filesystem to put in arch/ppc/mbxboot/ramdisk.image.gz. Then, build
with "make zImage.initrd" and the ramdisk image will be mounted as the root
filesystem at startup. An example ramdisk.image.gz is already included in many
of the kernel source tarballs on the ftp site. The easiest way to create or
modify the ramdisk image is to use the loop device on your Linux development
host to mount the file as a local filesystem, and then copy the files you
require into it.

Note that the minix file system code in Linux is not endian-independant, so
you can't build a minix file system on an x86 machine and expect to read it
on a PowerPC machine. ext2 does not suffer from this problem.

If your system has a hard disk, you can start by using NFS then build a root
file system on the disk and boot from that.

If your system has no ethernet, you may want to start developing on a board
that does.

Graham

PCMCIA socket driver (was Re: Non NFS boot)

[Magnus Damm]

I am working on a PCMCIA socket driver for the 8xx series.

I've managed to run a Xircom based ethernetcard and ATA-Flash.

The following boards will be supported:

BOARD                CPU

RPX CLASSIC LOW FAT  860T
RPX LITE             850 823
ADS                  860
FADS                 860T

This will make it possible to use any ATA-Disk as root fs.

The code will be available as a patch againts pcmcia-cs-3.1.8.tar.gz

Cheers /

Magnus
