Is the trace wrong or did I give a wrong address?
I got this sorted out, I was using a different variable for the netif_add.
Shouldn't that be
ip_addr_set_hton(iphdr-src, src);
And I read in the documentation that ipaddr is always network order

Hi
I'm using lwip 1.4.1 on big endian targets and it works. Now I
want to use the same software on little endian targets (ARM)
and have problems. Should that work from the lwip part? The
Ethernet frame of course is always big endian why it works
without problems on big endian targets. However I'm
Thank you all for your responses.
Finally I found the solution: long time ago I had problem with
ETH_IRQHandler and I disabled High priority task woken
void ETH_IRQHandler(void)
{
portBASE_TYPE xHigherPriorityTaskWoken = pdFALSE;

Hi Fabian,
for clarity's sake:
lwIP uses internally its own representation, and there are macros to
convert from network format to host format. I guess all systems are more
or less like that.
You are supposed to have a fast macro, preferably with machine code
instructions, because it is going to
Hi,
I'm using lwip141 in NO_SYS mode.
In random intervals a retransmission happens for a already acknowlegded
package. After that a dupack package gets send.
I've attached a Wireshark capture where you can see this at package 1516.

Thank you

All:
I define MEM_LIBC_MALLOC and MEMP_MEM_MALLOC to 0. But my application still can
use MALLOC and FREE function.
As LWIP help show, if the define them to 0, system use lwip internal allocator,
the internal allocator function name is malloc and free too ? I can’t find it
in lwip code.
Anyone
All:
I find that it call the malloc/free function in KEIL microlib file. But I
found that it get NULL from malloc call running application run malloc/free
frequently.
Who know how to fix ?
