Many of the docs are for a Windows Yagarto environment or using BDI2000
directly from a Linux cross-dev machine. Everything works seemlessly for the
in-the-box solution. However, there are no docs that tell how
to setup a mixed Linux/Windows development environment whereby
Windows provides the back-end remote gdb-server to the Linux
cross-development
host machine. Missing one detail like not having Zylin CDT installed in
Eclipse, or having an Insight debugger that is not compatible with the
cross-dev environment can cause havoc.

I view mailing lists as a tool to reap the collective experience for
cases that
go "outside-the-box" and are an adjunct to trying to resolve issues
after many
docs have been read and digested, which is what I did. In my case I
wanted to
find out why u-boot was failing to run after being loaded into SDRAM.
I'm finally
able to accomplish this with the tools that I have.

Sincerely,
