Hi ho,

[ LPC2368 FreeRTOS via Eclipse/yagarto ]

I am trying to get lwIP to work. I have uIP working. I notice none of
you ever discuss lwIP and there are some spatterings about uIP. It
seems to me that lwIP is much more powerful, like with DHCP. Do none of
you use lwIP?

Part 2: Does anyone have a "ethernetif.c" for the 2368? (I don't know
which phy, it's a standard development board.)

I just can't get this part to talk right under lwIP. I get interrupts,
i see the receive DMA ring buffer advancing, but i pull garbage out of
buffer. 99% of my "packets" are identical garbage (packet type =0x406, which is undefined). I can't get it to send at all, no noise
detected from it on the wire.

I have many times gone over the config of the uIP vs. the lwIP. It
looks like i'm banging the hardware identically, but obviously, i'm
not. I can't see how i am stuffing this up. Has anyone got this
working? LPC2368 and lwIP under FreeRTOS?

Oh, and this is an emergency. I demand answers. (I already tried
http://lmgtfy.com/?q=LPC2368+lwIP )
Danke in advance

lwIP is very widely used and has its own mail list.

Just had a quick look and there seem to be two examples in the files section
of this group. No idea how good they are though.

Take a look at the Ethernet drivers (emac.c) contained in the FreeRTOS
LPC1768 demos. These are a bit more sophisticated than the ones included in
the LPC2368 demos but I think they are compatible. You would have to change
the interface as they are written for uIP but they will be 95% of what you
want.

There are some good examples of using lwIP with FreeRTOS, but maybe not on
the LPC2368. For example:

Glad to be able to serve you :o)
