I'm not sure of this make udp header correctly .

Right. Did you analyze the uip_buffer (the udp frame) before transmitting
via your driver function?
How is your byte order defined? Maybe you use the wrong HTONS macro.

Betreff: [uip-users] dhcp bug ?
HI all.
Now I'm tring to set dynamic IP address of target board by using DHCP
application.
1. In main().
I call the dhcp_init();
2. In dhcp_handler()
It calls the send_discovery();
3. I receive UDP packet from target board on my pc, of course I can see
packet data by using wireshark.
4. Ehternet packet is ok!. IP packet is also ok. But UDP packet is not .
Source port and Destination port are zero.
Source port must be 68 and Destination port must be 67. right?
But this is set in dhcp_init();
5. So I forced to set Src port and Dest port and send packet.
But also it has zero src port and dest port.
Is this bug?
My Environment
uIP : 1.0
MCU : ATMEGA128
NIC : RTL8019AS
