TCP/IP solution for MCF523x

Arev — Wed, 25 Mar 2009 16:37:12 GMT

Hello,

I'm using a Freescale MCF5234/5235 and need to support the following Ethernet protocols

TCP/UDP/IP

DHCP (RFC2131)

DNS (RFC1034,RFC1035)

IGMP v2 (RFC2236)

DiffServ (RFC2474)

NTP v3 (RFC1305)

VLAN (IEEE802.1Q)

Does anyone know a RTOS and IP Stack that support these protocols for my platform.

VLAN, NTP and DiffServ are not supported by a lot of embedded systems.

Thanks for help

Bye,

Hi Arev,

have a look at Nucleus by Mentor Graphics. I'm not sure whether they support all of your wishes, but I know that there exist OSS SOAP Server, which you can implement.

Hi,

I have not run these specific protocols but many others not normally found in embedded real time system such as IMAP using RTEMS. The way I did this was to embed Python. It comes with all sorts of excellent and well written protocols including (from a quick Google) WSDL and SOAP. Things like NTP are directly supported by RTEMS.

I found the performance compared to the traffic flow acceptable and I still had RTEMS running all the real time parts of my application written in C++. The ability to just include a protocol and play was fastastic. We ended up writing parts of the application that handled the data in Python and just loaded the compiled Python code on the target file system.

RTEMS is http://www.rtems.org/
