I would recommend:

http://sources.redhat.com/ecos/getstart.html

Following this, it shouldn't be a problem to get
the tools installed and started with eCos.

If you see error messages, check the respective
email archives. And for eCos, get the source
from the cvs archive.

Hi Mr. Barrie,

I am a beginner who is working on building eCos on EB40. But I got quite a lot problem when install gcc and gdb. And then building eCos also failed. Can you tell me the environment of your PC and versions of your tools and STEPS of installing and building tools and eCos? If possible, can you write some tutorial to me? I would greatly appreciate it. Thanks in advance!

Best Regards,
Lin Ming

From what I've seen it is unused.The external memory being larger(512K)
it is used instead.And because they are discontiguous and there is no MMU
I think only one can be used...

[ECOS] Question: Atmel AT91 board family

[Pete Barrie]

Hi. Thanks to the group for various bits of help on eCos
I'm up and running and pleased with progress on AT91EB40 with
AT91R40807 (136K Internal SRAM) and 512K external SRAM

I'm evaluating this as a teaching platform for http://www.sli-institute.ac.uk
to augment (and maybe replace some) Wind River stuff.

I would like to use the AT91EB55 evaluation board.

Questions: are there any eCos/Redboot issues relating to
the AT91EB55 platform that anybody can share? This platform has
only 8K internal SRAM.
Is the larger 136K internal RAM actually used
in the EB40 port? I don't see a reference to this area in the
eCos Memory Layout section, other than 00 - 0FFF.

Has anybody undertaken the EB55 port? I would like to know
before I spend time doing this.

Thanks for any help you can provide.

Pete
