hi Simon,

Do you mean i need to install callback tcpip_init_done, which call dhcp_start, at tcpip_init calling and once tcpip_thread starts tcpip_init_done-->dhcp_start ?

Thien

If tcpip_thread is running before you call these functions, I do hope you are calling these functions from tcpip_thread and not from another thread!

That's exactly what the tcpip_thread does for you. The discover packet should be resent after some seconds. Maybe there's an issue with your port regarding timers?
