All: I use STM32 with lwip1.4.1 to run, sometimes it cause hardfault after running some days or some hours. I dump CPU PC register to know that it happen in tcpip_input function some code about memp.
#define MEM_SIZE (7*1024) #define MEMP_NUM_PBUF 20 /* MEMP_NUM_UDP_PCB: the number of UDP protocol control blocks. One per active UDP "connection". */ #define MEMP_NUM_UDP_PCB 3 /* MEMP_NUM_TCP_PCB: the number of simulatenously active TCP connections. */ #define MEMP_NUM_TCP_PCB 8 /* MEMP_NUM_TCP_PCB_LISTEN: the number of listening TCP connections. */ #define MEMP_NUM_TCP_PCB_LISTEN 8 /* MEMP_NUM_TCP_SEG: the number of simultaneously queued TCP segments. */ #define MEMP_NUM_TCP_SEG 10 /* 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 Does those define in lwipopt.h mean memp size is not enough for running ?
