I have add a printf in the pbuf_free function and before the assertion occur the pbuf->flag is equal to 54 (decimal)....
I don't understand what's happend.Do anyone know how I can solve my problem ? It seem the Pbuf is broken but I haven't any idea to solve this mistakes
in my software.This occur after a tcp_write and a tcp_output. I do that everywhere in my software and I haven't problems.
I'm using NIOS (Altera) , I have released my quartus 5.1 SP2, Nios 2 5.1 SP1 and I haven't data cache in my Nios core.
So, normally, this is not due to the bug reported by Altera. Thank you a lot Etienne Etienne Lanoy a écrit:
Yes I'm using Altera Nios but I have search the patch for the Data cache bug butI've not found it.I'm very desagree because in all my software I do the same action tcp_write and after tcp_output. There is no problem. Maybe something is broken in my software butI haven't any idea what can produce this assertion failure. I thank you a lot for your help. Best regards, Etienne Jan Ulvesten a écrit:Are you running Altera/Nios II? If yes, check out Altera website and/or niosforum.com. There is a problem with the Nios II data cache. A patch is available (to the IDE).

[lwip-users] Pbuf assertion failure Hello, I've a problem with an assertion in the file pbuf.c : In the function pbuf_free, the assertion LWIP_ASSERT("pbuf_free: sane flags", p->flags == PBUF_FLAG_RAM || p->flags == PBUF_FLAG_ROM || p->flags == PBUF_FLAG_REF || p->flags == PBUF_FLAG_POOL); occur. Before that I have done a tcp_write and a tcp_output I've never see it before. Do you know what's happend ? I use it all arround my software and in my new piece of code I'm writing fail this assertion... I don't understand. I thank you a lot. Etienne
