I am using the RAW API of lwip version 1.3.2 on a Stellaris CPU. I would
like to ping the network device (PC) on the other end of the cable. I didn't
see anything in the API to do a ping to another IP. Is this supported and
if so how would I do it?
Thanks,
DB

There's an example ping application in the contrib module/ZIP file
(apps/ping/ping.c). The upper half of the file contains socket code, the
Hi all,
Does anyone have a port to this family of micros? I guess I am just wanting
the eth_driver.c and eth_driver.h files ...
Many Thanks,
Bernie

Hi,
If you look at the LPC1768 demos in the FreeRTOS download you will find
uIP demos, but the drivers are probably just as relevant to lwIP.

Hi There,
Yes, I do have uIP working on the LPC1766, so I can use their drivers ...
they don't use interrupts, just polling, so will need to do some hacking
there
(I am also using it with QP OS so every thing needs to be event based ..)
Reason I am asking, is to try and save myself the work of
Hi again,
The drivers in FreeRTOS are interrupt (and I think DMA (?)) driven. The
driver moves a packet into a buffer pointed to by a chain of DMA
descriptors, thats it. I don't see why the driver would not be agnostic
of the stack it is being used with - the packets coming in off the
network
Hi Richard,
You are write, the uIP implementation is DMA driven, however the lwIP stack
sample which is written for the Stellaris MCUs writes to a FiFO, I don't
know if that is a DMA address on that micro , or not.
i.e in the read function you get the following:
Thanks Simon! The files weren't part of my distribution, I found them on
the download sight http://download.savannah.gnu.org/releases/lwip/;. I'll
give it a try and see if it works.
Thanks,

I think all you need to do is a memcpy into the buffer then tell the DMA
there is something in the buffer pointed to by the Tx descriptor. No
copying byte by byte. Although the DMA driver itself is more complex
than the simply FIFO driver, the actually copying of data is much easier.
The uIP
