Hello,
There seems to be a checksum issue that prevented a scussful ping.
(although it looked OK in wireshark)
After disabling CHECKSUM_BY_HARDWARE (for some reason it was defined)
, it works without any issues now.
Best Regards,

I've found that IAR use similiar flag; --no_unaligned_access.
So, now I get progressed , and see packes recieved and send.
Yet, for some reason althoyugh everything looks without errors in
wireshark, I get "request time out" for ping from PC.
I tried to ping from several PC but it didn't help.

Hello,
I get stuck in ip_addr_copy when called by ip_input.
I am using MEM_ALIGNMENT 4, and packed structs.
I tried many stuff, but nothing yet helped.
If I try MEM_ALIGNMENT 1, I get stuck in much earlier phase.
I'm using lwip 1.4.1 , which is a stable release as I understand.
Is there any idea
Hello,
I am trying to port lwip to uc/os (I use lwip 1.4.1).
But I get on packet recieve, immediately at first try "out of memory
in pool " error as following:
"
pbuf_alloc(length= 96)
memp_malloc: out of memory in pool PBUF_POOL
pbuf_alloc: allocated pbuf 0"
I observed memp_malloc(memp_t)
Hello,
I have issue on using lwip (1.3.1) porting for uc/os .
It seems that the OS hangs on executing :
etharp_raw()->
hdr->dipaddr = *(struct ip_addr2 *)ipdst_addr;
On further investigation, it seems that the problem is that ipdst_addr
is not 4 byte aligned but only 2 byte aligned (address

Hello,
Our Ethernet driver does not provide interrupt, and can only use polling.
I though that I can use rx thread as part of the threads created with
sys_thread_new.
But I am not sure about its priority related to tcpip thread , and the
rate for polling if there is new received packet.
