Multi port TCPIP on ARM7?

Development Boards MicroMod
1

Hello,

I’ve been working with an ARM9 board with linux to create a serial to ethernet interface.

Each serial port gets mapped to a specific ethernet port so that any data I/O gets mapped over ethernet.

I am starting to build an ARM7 based board and will not be running linux, but was wondering if its possible to have multi port tcpip connections?

I would like to map one of the serial channels to ethernet on this device but want to utilize the ethernet for other purpose as well, so I’d like to open a port for the serial data traffic, and then also run a web server on it. Is this possible with the ARM7 core?

Are there any tcpip libraries that woudl help me accomplish this?

Yup. It depends on your TCP/IP stack in firmware.

Yup. [lwIP and [uIP for example.](Svensk forskning för hållbar tillväxt| RISE)](Svensk forskning för hållbar tillväxt| RISE)

Hi

Take a look at the uTasker project at http://www.uTasker.com

It has projects for the following ARM 7 devices:

  • ATMEL SAM7X

  • NXP LPC23XX

(plus ARM 9:ST STR91XF, Coldfire M5223X, NE64 and Luminary Cortex)

As well as an optimised TCP/IP stack with various features - especially for single chip processors - it has an OS and various device drivers, plus a unique simulator allowing you to run the project on a virtual chip on the PC without any hardware.
