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. <http://lwip.100.n7.nabble.com/file/t2091/cubemx_udp_drop.png>
