Hi, I am using STM32F107 with FreeRTOS+LWIP with Netconn APIs.
I have created 4 tcp ports (server in listening mode) and trasfers data received to UARTS and viseversa. i.e. Ethernet to Serial converter (4 port). I works well for few hours but later it stops working. lwipopts defines are as follows: /* ---------- Memory options ---------- */ /* MEM_ALIGNMENT: should be set to the alignment of the CPU for which lwIP is compiled. 4 byte alignment -> define MEM_ALIGNMENT to 4, 2 byte alignment -> define MEM_ALIGNMENT to 2. */ #define MEM_ALIGNMENT 4 /* MEM_SIZE: the size of the heap memory. If the application will send a lot of data that needs to be copied, this should be set high. */ #define MEM_SIZE (10*1024) /* MEMP_NUM_PBUF: the number of memp struct pbufs. If the application sends a lot of data out of ROM (or other static memory), this should be set high. */ #define MEMP_NUM_PBUF 64 //100 /* MEMP_NUM_UDP_PCB: the number of UDP protocol control blocks. One per active UDP "connection". */ #define MEMP_NUM_UDP_PCB 6 /* MEMP_NUM_TCP_PCB: the number of simulatenously active TCP connections. */ #define MEMP_NUM_TCP_PCB 10 /* MEMP_NUM_TCP_PCB_LISTEN: the number of listening TCP connections. */ #define MEMP_NUM_TCP_PCB_LISTEN 10 //6 /* MEMP_NUM_TCP_SEG: the number of simultaneously queued TCP segments. */ #define MEMP_NUM_TCP_SEG 20 /* MEMP_NUM_SYS_TIMEOUT: the number of simulateously active timeouts. */ #define MEMP_NUM_SYS_TIMEOUT 10 /* ---------- Pbuf options ---------- */ /* PBUF_POOL_SIZE: the number of buffers in the pbuf pool. */ #define PBUF_POOL_SIZE 12 /* PBUF_POOL_BUFSIZE: the size of each pbuf in the pbuf pool. */ #define PBUF_POOL_BUFSIZE 512 Please suggest if i am missing something. Regards, Mohsin Madki.
