Hey
I wanted to insert a delay function to allow sufficient time for my lwip
DHCP configuration to bind so that i can print it successfully. I have a
while loop as follows :
while (1) {
xemacif_input(netif);
if (netif->ip_addr.addr) {
xil_printf("DHCP IP stack added
success\r\n");
*some delay function which does not effect
timeouts*
xil_printf("%d.%d.%d.%d\n\r",
ip4_addr1(netif->ip_addr.addr),ip4_addr2(netif->ip_addr.addr),ip4_addr3(netif->ip_addr.addr),
ip4_addr4(netif->ip_addr.addr));
xil_printf("%d.%d.%d.%d\n\r",
ip4_addr1(netif->netmask.addr),ip4_addr2(netif->netmask.addr),ip4_addr3(netif->netmask.addr),
ip4_addr4(netif->netmask.addr));
xil_printf("%d.%d.%d.%d\n\r",
ip4_addr1(netif->gw.addr),ip4_addr2(netif->gw.addr),ip4_addr3(netif->gw.addr),
ip4_addr4(netif->gw.addr));
break;
}
mscnt += DHCP_FINE_TIMER_MSECS;
if (mscnt >= DHCP_TIMEOUT_MS) {
xil_printf("ERROR: DHCP request timed
out\r\n");
break;
}
}
When i try to run the program without the delay function the printf is
still showing the initial values of the ip ( Which is 0.0.0.0 as it was
initialised to this value at the start of my program )
But the DHCP is working perfectly. The DHCP is successfully configured and
an IP address configuration is added to my netif . I even tested the echo
server . But to find out the new dhcp address assigned i had to go to the
network admin computer and check the dhcp server log manually to find out
the assigned IP. I feel the printf is a bit premature so i want to insert a
delay function to give it enough time to bind.
Can u suggest a suitable delay function which DOES NOT AFFECT THE TIME OUT
PROCESS .
Thanks a lot
Regards
Arvind
