Connection error cc2538 with RIOT os

[xkevin190]

I have been trying to emulate the riot gnrc_network example in renode with the cc2538 board, I have followed the renode documentation on how to use the IEEE802_15_4Medium and wireless.

How's is the problem

There is no problem when emulating, you can start RPL and server UDP, the problem occurs when I try to ping from one board to another or send data from a UDP client the console is completely stuck, and you have to close renode completely.

Hi,

Sorry to reply on a stale issue, did you manage to make it work eventually? I have the same issue and I found that you don't need to ping from one node to another, if you just ping yourself the terminal stucks too.

Also could you share more details about your setup? I type ifconfig on the first node and get fe80::acea:911c:fbc6:ee68, which looks good for a link-local address. Then I starts the udp server on the first node, which also looks good to me.

# on the first node
> udp server start 8808
Success: started UDP server on port 8808

But then doing this doesn't give me anything on the first node.

# on the second node
> udp send fe80::acea:911c:fbc6:ee68 8808 asdasd
Success: sent 6 byte(s) to [fe80::acea:911c:fbc6:ee68]:8808

Any clue what might be missing? (I didn't create the tap as mentioned here because I think we already create CreateIEEE802_15_4Medium to connect two nodes in renode)
