Hello
I’m just starting with beaglebone and I am trying to experiment with Uboot networking to get TFTP going.
When I get to UBoot prompt and run dhcp, it keeps broadcasting and once it hits 10th broadcast it restarts without getting an IP address:
`
link up on port 0, speed 100, full duplex
BOOTP broadcast 1
BOOTP broadcast 2
BOOTP broadcast 3
BOOTP broadcast 4
BOOTP broadcast 5
BOOTP broadcast 6
BOOTP broadcast 7
BOOTP broadcast 8
BOOTP broadcast 9
BOOTP broadcast 10
Retry count exceeded; starting again
link up on port 0, speed 100, full duplex
BOOTP broadcast 1
BOOTP broadcast 2
BOOTP broadcast 3
BOOTP broadcast 4
BOOTP broadcast 5
BOOTP broadcast 6
BOOTP broadcast 7
BOOTP broadcast 8
BOOTP broadcast 9
BOOTP broadcast 10
Retry count exceeded; starting again
…
`
here is output of printenv:

I even tried setting up static IP:
`
`
U-Boot# setenv ipaddr 192.168.168.236
U-Boot# ping 192.168.168.236
link up on port 0, speed 100, full duplex
Using cpsw device
ping failed; host 192.168.168.236 is not alive
`
`
As you can see I can’t even ping myself!!
This is the static IP address setting I am using:
192.168.168.236
Netmask:
255.255.254.0
I can’t even get to using TFTP with this! It fails to even get a network address!
The network is fine, it is not firewalled, MAC filtering is disabled, a random PC on the network immediately picks up an IP address.
Can someone please help me understand this and help me fix it?
Thanks
