Re: [lwip-users] fragmentation failure with stm32 if length > 1704
Hi, I've solved this issue after increasing size as was suggested here. Thanks ! (The issue was also posted here: https://community.st.com/s/question/0D50XBozSc5SQE/ethernet-fragmentation-issues) Yet, whenever lwip receives (from PC) big packet , above its limit, it gets into exception as was described above. This seems like a high security issue. Any idea how it can be solved ?

Re: [lwip-users] fragmentation failure with stm32 if length > 1704
Hello, We see the using packets above ~6000 bytes, lwip get into unaligned access exception (it first does not respond to the ~6000 packet from PC, and then after several seconds , or after sending a small packet again, it gets into this exception: ->lwip_cyclic_timer ->ip_reass_tmr ->ip_reass_free_complete_datagram ->iprh = (struct ip_reass_helper *)p->payload; Is this functional issue a chip issue or lwip issue ? I am using latest CubeH7 (ver 1.5) , which also includes the udp echo example. Thing I've tried: 1. CubeH7 1.5 comes with lwip 2.0.3, I've tried to upgrade to lwip 2.1.2, but it did not change result. 2. I have tried to increase PBUF various size, but it did not help, I am not sure why. This issue can very easily be reproduced with eval or nucleo board for stm32h7. Thank you for any idea, Ran -- Sent from: http://lwip.100.n7.nabble.com/lwip-users-f3.html ___ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users
[lwip-users] fragmentation failure with stm32 if length > 1704
Hello, I use a simple echo udp example for STM32 Hal , with stm32h743 EVAL. I encounter exception (it shows as unaligned exception, but the address is not anything we allocated. This failure happen if I increase the packet size from 1704 to 1744 ! tcip_thread->tcip_timeouts_mbox_fetch->sys_check_timeouts->lwip_cyclic_timer->ip_reass_timr->ip_reass_free_complete_datagram exception error of type unaligned access. I tried to increase various size in lwipopts.h but nothing helps. Is it stm32 issue ? Any idea ?

It's seem like only LWIP stack/threads stopped responding, it is not a crash of freeRTOS, because everything else behaves normally.

[lwip-users] udp echo stress test with LWIP - crash LWIP
Hello, I am using LWIP with stm32, running udp server echo in my board. From pc I run udp client stress test. I noticed that with RTOS lwip get crash (it even can't ping anymore, after stopping the stress test), but without RTOS it behaves without any issues. Thing I tried: 1. compiled the application with speed optimization 2. changing tcpip thread priority from high to realtime. I can't say what exactly happened to LWIP which caused it to stop responding to ping. Is there any idea what else we can do or how to debug this issue ?
