lwIP PROBLEM (pbuf)

Hello, I'm using LWIP 1.1.1 on Nios II 5.1 version.

For unknown reason, I often have some pbuf assertion failure "pbuf sane flags" when the function pbuf_free is called.

On the LWIP dev community someone has said to me that there is a bug

with NIOS 2 data cache.

He has said to me that a patch was available.

Anybody has this patch ? Do you already have these assertions failure ?

Thank you

Etienne

    It may be the problem of the data cache...

    try to update your Quartus and especially nios II distribution to the latest one. also apply all the service packs!

    bye
