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
