Re: Adding DHCP, AutoIP and IGMP to LWIP support
Posted: Fri Dec 13, 2013 11:19 am
Hi all!
I can´t get to work multicast communication. DHCP is already working. AUTOIP is unwanted.
Problem: still waits for semaphore. Nothing is catched.
My steps for IGMP config:
added into lwipopts.h:
added into lwipthread.c:
in low_level_init();
in lwipthread();
and then in lwipthread main cycle added:
added into in mysrc.c:
Is there something what i doing wrong, or something configuration is missing? I dont want use any timers and autoip.
Thank you.

Problem:
Code: Select all
err = netconn_join_leave_group(conn2, &mcast_addr, &thisif_ptr->ip_addr, NETCONN_JOIN);My steps for IGMP config:
added into lwipopts.h:
Code: Select all
//LWIP_IGMP==1: Turn on IGMP module.
#ifndef LWIP_IGMP
#define LWIP_IGMP 1
#define LWIP_RAND() ((uint32_t)rand())
#endif
added into lwipthread.c:
in low_level_init();
Code: Select all
netif->flags |= NETIF_FLAG_IGMP;in lwipthread();
Code: Select all
netifapi_dhcp_start(&thisif);
igmp_init();
igmp_start(&thisif);
and then in lwipthread main cycle added:
Code: Select all
igmp_tmr(); added into in mysrc.c:
Code: Select all
ETH->MACFFR = ETH_MACFFR_PAM;Is there something what i doing wrong, or something configuration is missing? I dont want use any timers and autoip.
Thank you.
