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.

Best regards,

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).

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);


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.
