Re: DHCP problems
Andrew,
Thanks for the input.
The address is mac ff:ff:ff:ff:ff:ff & 255.255.255.255. I checked my old
working version (1.xx) to this one and there is no difference in the
discover and the offer. There must be a problem with receiving broadcast
frames. Both TCP & UDP work fine. The eCos snapshot I took is about a month
old. I am going to take the latest off the Ecoscentric site and try that.

I have upgraded from eCos 1.0 to the latest eCos version. Everything is
running fine except for DHCP. TCP & DNS work fine. The DHCP sends the
request to the server and a response comes back from the server, but the
DHCP client never receives the frame ( I see the frame on the sniffer).
It
seems that it will not receive a broadcast frame. Any ideas?
What address is the frame sent back to, both IP address and MAC
address. There have been problems in the past of the server doing this
wrong, or not honoring the Broadcast flag. See section 4.1 of the RFC.
