Also I removed the HAL IRQ handler for UART and wrote my own which use FIFO. This helps a lot !
The HAL has quite strange implementation of serial port data. Now I have 64 byte output cyclic buffer, which is more then enough for my serial text terminal.
Also enable in lwipopts.h
#define SOCKETS_DEBUG LWIP_DBG_ON
and try to use timeouts.
// Setup timeouts
if(lwip_setsockopt(socket_fd,SOL_SOCKET,SO_RCVTIMEO,&rx_timeout,sizeof(tx_timeout)) <0){
lwip_close(socket_fd);
printf('
Net, Failed to set timeouts
');
}
if(lwip_setsockopt(socket_fd,SOL_SOCKET,SO_SNDTIMEO,&tx_timeout,sizeof(tx_timeout)) <0){
lwip_close(socket_fd);
printf('
Net, Failed to set timeouts
');
} �?�?�?�?�?�?�?�?�?�?
