AT91RM9200

Cogent

make an at91rm9200 based board - the CSB337. It's about $400. I'm not sure if anyone's ported Linux to it, but RTEMS does run on it.

CSB337.

Thanks!

They're selling an RTEMS BSP for about $6000, so ~$6400 looks like the lowest priced option so far..

Does it have to be the AT91RM9200 ? I have just ordered the UNC20 development board which has a NET+ARM (NS7520) with uCLinux.

We haven't ported our system to the AT91RM9200 yet, but have done several other ARMs, including the Samsung parts with intergrated Ethernet. A complete open Forth, TCP/IP stack, echo server, and multithreaded Telnet and Web (with CGI and ASP) servers occupies about 110 kbytes. Costs are: Compiler GBP 1250 ~USD 1950 TCP/IP 2495 3870 ------------------------------- 3745 5820

It isn't in C, but it's there and it works.

Take a look at

It hasn't been ported to AT91RM9200, but might be worth a look.

It's free so you have 5k left for porting ;-)

I had looked at the NS7520, but was leaning toward the Atmel part because it has many uarts and serial ports. However, the unc20 has an out-of-the-box IDE connector, which is something missing on the cogent board for the AT91RM9200. What is the ordering information for the ucLinux development kit with the unc20?

[Also, just out of ignorance, I assume that ucLinux supports the ISO9660 filesystem, and allows an application to play audio from a CD drive if a CD is inserted?]

So, just to make sure I am understanding this, Atmel has published a uCLinux distribution for their AT91RM9200 development kit?

I am not aware of an IDE connector for the UNC20. AFAIK it supports CRAMFS (Ram file system), a Flash file system and NFS. You can of course mount your ISO9660 CDROM over NFS. The NS7520 has 2 UARTs which are capable of HDLC as well.

If you get the development kit for the AT91RM9200 there is a Linux port available "running off the shelf". Cost for the board is $5k. You can get the Linux port separately free of charge, but then there is a porting effort to, lets say, the Cogent board. The main difference between the DK and the Cogent board is the on board LCD controller The Atmel board is using a more advanced version. Why IDE; is not the flash card connectors what You are looking for? YOu might be able to run over USB (at reduced speed)

uCLinux

No it is full Linux. Ulf Samuelsson (I work at Atmel so I should know)

Nope. Different from the previous AT91 devices based on the ARM7TDMI, AT91RM9200 is based on the ARM920 architecture that contains, among other things, an MMU. This means the 9200 is capable of running plain Linux.

This application uses an ATAPI CD ROM drive. I need to pull files off of the CD and store them into dataflash. This box can connect to its server over the Internet, but if this connectivity is not available, the service provider mails out physical media once a month, and CD's are by far the cheapest.

This application target board also has to decode MP3 files among its various functions. It looks like there is an AC97 codec on the devkit board, and I assume I can find reasonably priced ARM920T MP3 decoders.

Is there somewhere on the Atmel web site from which I can download this?

Well, that certainly works. However, the ARM9's got enough horsepower to decode the files itself, and your DK's got a codec on it that would work nicely. Just out of curiosity, what does it cost to get source code for a good, fixed-point MP3 decoder optimized for ARM?

Hello,

Could you give me a rough price of this chip ?

Greetings,

Martin

Dont really know, but my guess is that it should be $5 - $10 in some decent volume.

How about these USB to IDE ICs ? There are quite a few single chip solutions that are used to connect IDE HDs and CD-ROMS to a USB port. I think the support for these devices are now standard in Linux. I had no problem getting one of these devices going on Redhat 9.

The NS7520 device on the UNC20 module I mentioned in a earlier post has got a USB interface that can either be a host or a slave port.
