Hi all,

Did anyone try or knows how to configure and run the echo_server sample application on qemu_cortex_m3 ?

I’m following the instructions on: https://wiki.zephyrproject.org/view/Networking-with-Qemu

When running on x86 qemu everything works fine and I can ping the target server but when trying to use arm qemu ARP requests are not answered.

I’m running the command: make pristine && make BOARD=qemu_cortex_m3 qemu

Is there something I’m missing?

This is the configuration I get from the network shell in ARM:

Hi,

indeed –q option doesn’t work on my machine.

When running nc with echo and pipe nc doesn’t wait but when starting nc and then typing text it does wait.

But… I would like to send (and then receive) a file. I’ll need to figure it out.

Thanks Piotr!
