Hi,
I am using lwip1.4.1+FreeRTOS+ Ti Tiva C Tm4c1294.
Actually, I used lwip1.3.2 and the modules associated with socket
communications worked fine.
However, as I ported from 1.3.2 to 1.4.1, it did not even get socket fd
from lwip_socket().
*socket_fd = lwip_socket(AF_INET, SOCK_DGRAM, 0);*
This function always gives me *NULL*(0).
What I have changed is implementing *sys_mbox_set_invalid(),
sys_sem_valid(), and sys_sem_set_invalid()* in *sys_arch.c*
Also, changed default numbers to the below:
#define SYS_THREAD_MAX 8
#define SYS_SEM_MAX 16
#define SYS_MBOX_MAX 16
I attached *lwipopts.h*
Thanks,
Jin
