Try and increase your MEM_SIZE.

Hello,
I work with STM32F217 + LWIP 1.3.2 + FreeRTOS 6.1.0
I have several services in parallel:

Hi,
As default the MSS size is defined to be 1500 bytes. This is too large for
embedded.
Try to reduce it to 536 and increase the total number of PCBS.
These are my settings:

a lot of data that needs to be copied, this sho

This does look like a resource problem somehow. Possibly a timeout
firing before the jquery response completes (not enough CPU power), or
insufficient memory to respond, that sort of thing.

Hi Marty,
You are absolutely correct it is system dependent.
As you can see from my reply, I used a 7K bytes pool for LwiP.
16M byte is a super computer compared with what I do. I worked with ARM9 with
96K RAM :-)
With just 7K RAM dedicated to LwIP pool I was able to run a WEB server with
JQU
Dear:
7K RAM for lwIP pool is enough, I use cortex m3 with 128K ram, I allocate 7KB
for it.
My web server is more heavy than yours. My largest size of file is upto 170KB.
It works well too . you should check the RCV_BUFFER NUMBER AND SND_BUFFER
NUMBER for it.
In my system, I define them to 2, a
It’s a hole different story if it’s a single file aka connection or serving
many. I have seen this issue with my implementation. Not having enough heap
and thus a file wasn’t sent.
I use a 4K heap and serving the jquery 91k with multiple connections but
have optimised the drivers a lot.

We have some real-time constraints, such as a touch screen that we want

Actually it was not a chained pbuf problem since it is perfectly working for
UDP. I guess my TCP server code is wrong...
I'm gonna improve that.
Thank you for your advices !!

Hi,
I don't clear this problem, I have difficulties to understand why the
recvfrom() function still blocking when it receive about 2700 packet of data...
I have check all the buffer size, it seems it's a transmit message problem in
the fonction netconn_recv_data() in this line :
sys_arch_mbox
Thank you for the response. Unfortunately we have tried these things and still
can't get it to work.
Interestingly, we can't get communication with our setup like this:

I tried to change the parameters but without success.
In same time I port to lwip 1.4.0, and I corrected some minors bugs in UDP
services by changing "rcv" by "rcvfrom" but it didn't change anything.
The problem appears only when the others services are activated. In
webserver only it works corre
I did the test back with the small webserver example and html files from ST
and this is the same problem. However the files size are smaller. Some files
are not loaded.
And after some refresh from Chrome, the webserver thread is crashed but the
rest of the card is working.

We've tried a PC that fails in the 1st topology and it works in the 2nd
topology.
We'll double check the addresses and stuff. I think you are right about
Wireshark is seeing the packet but the stack is not passing it on for some
reason but I can't figure out why.

Sounds like a routing problem to me. Try a PC<->PC IPv6 connection
through your Intranet and see if that works.
PS: I'm using redpine modules too.

Hi Seba,
Sounds like a lower layer problem.
If you are sure, the packets arrive at your STM32, check its MII
counters, Interrupts (Flags+Breakpoint), DMA flags (RBUS!)
