I've got cygwin on an XP box and have installed eCos 3.0, but cannot
find any package for the TS7250 or the ARM9-EP9302 processor.
The s/w that came with the board appears to have the redboot source
but I think it is a eCos 2.x version.
Is there an existing package for this board or is there a way to
'import' it from the 2.x source?
Thanks for any pointers in getting going in the right direction!
This board is not part of the public tree.
You should be able to get the original sources from Technologic Systems
I believe the source for the redboot is on the CD supplied from
Technologic Systems, but I believe that it is for eCos 2.x tree.
Can I just copy that over to the eCos 3.0 tree that I've installed or
does it need to be 'Imported' via the config tool?
As a starting point, you should be able to copy the directories
containing the additional eCos HAL and driver packages from your TS7250
repository to an eCos 3.0 or eCos CVS repository and then copy the
relevant "package" and "target" declarations from the ecos.db file in
the root of your TS7250 repository to the eCos 3.0 or eCos CVS ecos.db file.
Note that there is also a patch providing full eCos support (not just
RedBoot) for a number of EP93xx parts:

From what I could tell, the original Technologic boards (TS7200, etc)
were based pretty closely on the Cirrus eval boards. Technologic started
their version Redboot using the Cirrus modifications to eCos 2.x from
about 2005. Cirrus updated their code for a while and released it
publicly on their web site, but I believe that Technologic stayed with
the original fork. A few years back, Brian Austin at Cirrus claimed
that the company was going to release the code to the public repository,
but no more was heard from them.
