MCU-PLUS-SDK-AM273X: How to make 4 tcp servers work based on LWIP

Hi,

My customer would like to use 4 tcp servers by LWIP on AM2732 but found if the 4th server is created, all tcp servers can't be connected by clients.

Customer tried to modify the parameters in opt.h as below, but still met problem. Would you pls kindly help?

#define MEMP_NUM_PBUF 128
#define MEMP_NUM_TCP_PCB 10
#define MEMP_NUM_TCP_PCB_LISTEN 10
#define MEMP_NUM_TCP_SEG 128
#define MEMP_NUM_NETCONN 20

BTW, if only creating 3 tcp servers, they are working ok.

Thanks,
Chris
