Linux activity on ARM9

Hi Ian, and others.

I, and some others at Center for Embedded Software Systems at Aalborg University, expect to start looking into getting Linux running on an ARM9-based board (Cogent CSB337) within the next month or two.

We haven't received any hardware yet, though...so right now i am mostly reading and trying to understand how to use Linux for embedded systems.

Also, we are looking at using the eCos operating systems

Out of pure curiousity - why are you asking?

Best regards,

Thanks for the input. I am asking because we are considering this as one option for a new project architecture. The ARM9-Linux user community seems very small now, but it might be growning because of the low cost of some of the new chips. I don't know any way to really "measure" this, so I'm asking here to hopefully get some indication. We prefer our architecture to be as "mainstream" as possible.

Hello Tue,

After your evaluation on the eCos, how about the result?

B.Rgds,

Jason -

I'm curious as well. I've been looking at eCos lately and would like to hear anyone's experience with it.

My particular interest is with the Coldfire 5272 or 5282.

Evaluation, hmm, i am hesitant to give any firm conclusions here, as i have only worked with eCos for some weeks now, and i'm starting to get a grasp of its architecture.

My impression is that eCos appears to be a solid, flexible OS in general, but as no practical experiments has been conducted at the moment, i don't know how well it supports the ARM architecture, and specifically the Cogent development board and breakout box.

One point to be aware of, is that eCos is radically different from Linux, in the sense that the eCos kernel is application-specific, i.e. the application and operating system is linked to a single binary, which then runs on the target.

If anyone has results or experiences from more practical experiments, i would also be glad to read about them.

Best Regards,

Hi Ian, FYI, The Atmel AT91 support team has just released an App Note on How to interface a Hard Disk Drive to the AT91RM9200. Drop them a mail and ask for it. use Atmel dot com, userid: at91support

Hi Tue, Nice to see more interest for the AT91RM9200 Cogent Board. I worked with Nohau U.S to convince Cogent to build the board early this Year I hope that You are aware of the existing Linux port for the chip. If You drop me a mail,I can provide an ftp link to the AT91 ftp server.

If you want to design your own system, then we may be able to provide some free chips.

I am quite often in Denmark, and Atmel plan to run some seminars there in Aarhus in November. Chek the Atmel website for info. It would be fun to meet.

You may want to check out the arm-linux mailing list ( snipped-for-privacy@lists.arm.linux.org.uk).
