I am running coLinux downloaded from Analog Devices website. It is
described here:
http://docs.blackfin.uclinux.org/doku.php?id=colinux

The main coLinux webpage is here: http://www.colinux.org/

Preconfigured coLinux can be downloaded from Analog Devices. Download and
install the larger package (110 MB). The smaller one is meant for
upgrading an already installed coLinux.
http://blackfin.uclinux.org/gf/project/bfin-colinux/frs

This particular coLinux is a preconfigured Debian. It installs very nicely
and runs cooperatively with Windows. You do not need dual boot. You can
start/stop coLinux at any time while Windows is running. From the Windows
standpoint it behaves like an application. In fact it is a full Linux
running on a virtual machine alongside Windows.

Contrary to what the installation readme is saying, coLinux does not need
much memory. I am now starting coLinux with only 64 MB memory, which is
sufficient to cross-compile Linux kernel.

The installation file contains just Linux without the gcc or kernel
sources. After you install coLinux, you can take it into three directions:

1) Use it to run Linux applications. Display graphics on your Windows
desktop with X server, which is included.

2) Use it to develop i386 apps and/or i386 kernel. You will need to
download and install the usual i386 toolchain from one of many Linux
websites. I would guess Debian is preferred because this particular
coLinux is Debian.

3) Use coLinux to cross-develop Blackfin, which I am doing. For this you
will need to download the Blackfin toolchain from the same website.

I am only interested in #3. However, coLinux is equally usable for #1 and
#2 as well.

I would say that coLinux is the least painful way to dive into Linux
development, whether #1, #2, or #3. Compared with the usual pain of
installing Linux, coLinux is sheer pleasure. You do not need to
repartition your disk or install lilo or anything like that.

Here is a good info webpage concerning Linux, with book recommendation:

http://docs.blackfin.uclinux.org/doku.php?id=references_and_pointers

Finally, the Linz Oberon 1.7 for Linux can be downloaded from sourceforge:
http://sourceforge.net/projects/oberon/
oberon-1.7.02.tar.gz

In the latter archive there should be some useful hints how the V4 was put
on top of Linux.

Hope it helps,

W.
