Ouch! tcpip_callback() takes a void pointer as first argument. You are
*first* calling tcp_write with the parameters supplied, then passing the
return
The two APIs can coexist.
regarding your code: Sorry, this code is so horribly wrong :-( I am sorry
for being rude - you also need a LOT of education in C code. And, if your
compiler compiles this, the warning settings are way too relaxed or you
really should read and fix all compiler warnings.
I cannot because my webserver is already running with raw api.
In my Send task I try now…
tcpip_callback(tcp_write(pcb, ucrecBuff, supersize, TCP_WRITE_FLAG_COPY),NULL);
tcpip_callback(tcp_output(pcb), NULL);
but without success. After the first message sent the system crashed.

Use socket API and you can use threads without problems.

Sounds like you are calling lwIP functions from another thread than the lwIP
thread, in your case the CAN thread.

Hello,
I am using lwip 2.0.2 RAW API + freertos 8.2.3.
I have to send a lot of data received by CAN to
Ethernet.
I receive CAN data in a CAN Interrupt and enque them here.
In a 3ms task I periodically check the queue for new data
and send them via tcp_write() and tcp_output().
It seems
