[lwip-users] HTTP server with null files

[Michał Karczewski]

I'm working on http server that is using netconn api and could read files
from SD Card. I'm using STM32F429. I've configured LwIP, FatFS and FreeRTOS
that it is possible to ping using tcp and udp protocol. After some
pre-configuration of netconn server I tried to connect using browser. In the
result, standard pc browser download window is coming and starts to download
file with random name which contains only NULL values. The size of
downloaded file matches chosen file from http_server_serve() function, so in
some way it is connected with file on SD Card, but problems are with data
value.

Next to that I can tell previously I configured http server without any API
(raw version) and I hadn't had any problems with displaying website from SD
Card.
