RE: [lwip-users] No TCP connection

[Amir Bukhari]

I have test also with the following:

void lwip_init(void)
{
#ifdef STATS
        stats_init();
#endif
        sys_init();
        mem_init();
        memp_init();
        pbuf_init();
        etharp_init();
        
        ip_init();
        udp_init();
        tcp_init();
        
}

void net_init(void)
{
        struct netif *netif_eth;
        uint8 *addr;
        
        IP4_ADDR(&eth_gw, 141,21,4,1);
        IP4_ADDR(&eth_ip, 141,21,7,245);
        IP4_ADDR(&eth_netmask, 255,255,252,0);
    
        netif_eth = netif_add(&netif_eth0, &eth_ip, &eth_netmask, &eth_gw,
                  NULL, mpc5200_init, ip_input); 
    netif_set_default(netif_eth);

        netif_set_up(netif_eth);
                
} 

I call lwip_init first and then net_init and also doesn't got any
connection, but as I said I can pinging, that mean IP layer works.

This looks like you're mixing up the APIs.

The semaphore stuff implies the sequential/socket API where you have e.g.
netconn_new(NETCONN_TCP).

I'm unsure if this can be of any harm, maybe not.
I wouldn't dare to mix them. This is also one of the current problems with
the unixsim example.

The same sort of mixing happens there,
and this is very confusing to new users.

I'll have a look if the sequential API is documented clearly enough.
