[lwip-users] Weird UDP packet loss

[ismailfatih]

Hi, im using stm32f7+ freertos+lwip (raw api). My system handles web server
(httpd) and udp data communication (receive callback based). My frame length
is 572 bytes and my FPS is 40 (22880 bytes/sec) at start. When i increase
the package number to 8 times (8*572*40 = 183040 bytes/sec) it drops a lots
of udp packages.(Especially dropping starts after 6 times =
6*572*40=137kbits) The weird thing is: if i decrease it to 22880 bytes/sec
again it cant returns the normal situation it still drops. I have to reset
it for normal again. Im not expert lwip so i think there is a problem about
buffers etc.. Is there any specs that causes this situation ?  I need an
advice.
