Re: [lwip-users] LWIP 1.4.1 uploading problem

[Vass Szabolcs]

Hi,

    Thank You Mr Caprile and Mr Simon for Your advices. I will look if 
pbuf are properly freed or not and I will look the tcp receive window 
too. After that I will be back.

    Excuse me Mr. Caprile but I cann't post to this open list neither 
my code, and neither my traffic. This code isn't public , it is a 
development. Hope You understand me. The lwip stack what I get from ST 
through STM32CubeMx is properly work with other smaller file uploading, 
and I think that not the difference from Your stack is the problem. 
Furthermore the all of other functionality is working good. So please 
don't blame the ST. If the problem willn't resolve I will try to explain 
it with more deatils but without posting of code.


Kind regards,

Szabolcs Vass
