I run my programs over the network using RedBoot. RedBoot is set to use
the ip 172.16.1.240. My eCos application is set to get an IP using
DHCP. It gets an ip of 172.16.1.11. Now, I ran my eCos program from
RedBoot, and now a reset of the board does not reset the IP to
172.16.1.240. It's almost as if the eCos application has taken over
some how. Of course RedBoot doesn't listen on 172.16.1.11 so I can't do
a GDB connection to there. Also, running fconfig through a serial port
shows that 172.16.1.240 is in fact the IP RedBoot is setup for.
Any ideas why this might happen? I've been running eCos programs with
network support enabled for the past day using the network GDB of
RedBoot and this hasn't occurred until now.

Have you set a static IP address in your CDL configuration? Or in your
flash configuration?

My flash configuration for RedBoot is a static IP. My configuration for
eCos is DHCP.

Do an fconfig -l and recheck that it's not using BOOTP.
It's been suggested it may be something to do with the ARP cache on your
local machine. Try looking at that.

That was the first thing I did, but the BOOTP option is set to false.
It's fixed now because I downloaded RedBoot to the board again. I
didn't change the flash configuration because it stayed the same. So,
it's not an emergency. If you happen to think of another reason why it
might happen, let me know.
