In the errata doc provided by Altera, it seems this bug is now corrected ?
I'm compiling a new version of my software with this version of quartus ...
We will see ...
Thank you
Etienne

The problem is related to an unlucky sequence of machine instructions actually found in pbuf_header's code (!). Removing the data cache or changing the size (diff. from 32 bytes) will help. ALtera does oalso provide a fix.But; the Altera fix didn't help me for some reason which I don't know. I did remove the cache entirely. If you are able to make thins work after installing the Altera fix, please inform me.

[lwip-users] Pbuf assertion failure Yes I'm using Altera Nios but I have search the patch for the Data cache bug but I'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 but I haven't any idea what can produce this assertion failure. I thank you a lot for your help.

[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.
