I'm looking for an embedded microprocessor that can run a web server. The purpose of it will be to configure an embedded system via a web page similar to how you configure most routers. I've been looking around and have found a few linux ports that run on the Freescale ColdFire microprocessors and the ARM microprocessors however they all are made for specific development boards. (Looked into uClinux the most). Is it possible (without several hours of work) to modify them to work in a custom design? I can't use pre-made boards because my design must be very small. I like the upper end ColdFire chips because they have a built in Ethernet PHY and MAC saving space by not needing another chip for that. Any tips on processors to look at? Any tips on linux ports to look at?

I really doubt you can get uCLinux running on a custom platform without spending several hours on the project. I would guess you'll have to spend a minimum of week or two to get uCLinux running on a custom target. Of course, the same is going to be true for any OS capable of running a web server. Still, you might want to take a look at more lightweight options such as eCos http://sources.redhat.com/ecos/. -- Grant Edwards grante Yow! My BIOLOGICAL ALARM at CLOCK just went off...

They also have a HW TCP/IP stack as well if the FREE software one does not do what you need... IT depends how much you want to do. There are quite a few systems (like EMIT) that do not need an OS let alone one as large as Linux.

If low throughput is ok (as it is on many embedded systems) then there are a lot of low cost options: http://www.freertos.org/embeddedtcp.html http://www.rabbitsemiconductor.com/tcpip-programming.htm http://www-ccs.cs.umass.edu/~shri/iPic.html http://www.ethernut.de/ http://www.rowley.co.uk/msp430/uip.htm etc. etc.

The source code is provided. You don't need any file system. The test code runs on linux but it should be easy to port it to any rtos that has a tcp ip stack and that supports sockets. http://www.ddjembedded.com/resources/articles/2001/0110h/0110h.htm

With their ZTP 1.5.0 they provide a nice TCP/IP stack with e real time kernel. A development kit (EZ80F910100KIT) is offered at a reasonable price of $99 (DigyKey, Mouser, ...). The core module( eZ80F915005MOD) with controller + FLASH, RAM and PHY measures only 4,5 x 5 cm, so it might be small enough to meet your requirements. Harald

Take a look at our coldfire solutions. www.netburner.com The lowest cost is the MOD5270 You can start with our modules and if the $59/1K price is too high for production then you can license the IP and build it yourself. For a completly independant review take a look at the recent electronic design article. http://www.elecdesign.com/Articles/ArticleID/10580/10580.html Paul

Only problem is limited number of I/O. But has anybody experience with the ME? How fast can the ethernet (and total I/O) speed got? I need almost 3 Mbit/s. -- @jhol
