I am currently working on a project based on the LWIP-Stack (1.4.1).
The goal is to create a working webserver-interface on a NIOS development board.
I am failing for a long time on fixing a problem with the HTTP implementation which causes an assertion
(Assertion "tcp_write: arg == NULL (programmer violates API)" failed at line 384 in src/core/tcp_out.c).
This makes it impossible for me to start a working Webserver and to go on with my project.
It seems for me as if the pointer referring to the outgoing data is wrong while the sent data has nothing in common with the HTML documents I created in the fsdata.cpp.
Is this a known problem and in case yes is the a fix available already? I wasn’t able finding a solution myself or by web-research.
