Need uidance for a networkstack implementation in AT91SAM7x

Iam very new to embedded s/w.. and i have to implement a new kinda network stack on top of a TCP/IP and a UDP stack. Now i dont know where to start.

I realise that i need a EMAC driver fo rthe board and then plug in the TCP/IP UDP stacks.

How can i start with the EMAC driver..do anyone have a working EMAC code for AT91SAM7x-Ek ? i am using yagarto tool chain.

And please guide me for the TCP/IP and udp stack development or using a some open source code....

I i see my board connect to ethernet then a great deal of work is done !!


thanks

http://www.sics.se/~adam/lwip/ is a great TCP/IP stack that I've been toying with recently. Getting a driver written, getting the stack working with your embedded OS, and getting an application to run on top of it is not a simple thing. Good luck![/url]

hello,
take a look at freertos:
www.freertos.org

I had a look at the IwIP, but iam having a hard time in compiling the stack with my sample application code! I guess i must learn the makefile stuff.

What abt the EMAC ! driver. I looked at the freertos ,and there is a webserver example and that demo also didnt complie with ARM GCC.

Thanks for u r advises. I ll keep updating info here in this tread.

The lwIP_Demo_Rowley_ARM7 port from FreeRTOS compile with gcc. You will find there the emac driver that you are looking for.

thanks !!

So the EMAC driver must be kinda ripped of from the freertos huh... cos i see that some freertos routines are used in it. but i dotn want to used any rtos.

lemme see if it works
