Upgraded Cobra to 4.2. Network not working

I just upgraded my Cobra board to the latest firmware ( But, networking doesn’t seem to work anymore. I’m trying to use the builtin Ethernet adapter. Is 4.2 not supported for Cobra?

EMX is supported in 4.2. Networking is MUCH different in 4.2, in general, so your code is unlikely to just move easily. You will need to spend a bit of time to migrate.

I haven’t tested any code yet. Just trying to ping, but I get no replies. Tried both DHCP and static IP address. It does not send out any DHCP requests. Do I have to have to enable the Ethernet adapter in some way?

yes, in code.

Edit: here’s a reference I have that might help http://www.ghielectronics.com/community/forum/topic?id=10901
