wpantund can not be configured for nrf52840-DK working as NCP

[zhliao]

Hi,

I am trying to follow the OpenThread tutorial to build the nRF52840 NCP:

https://codelabs.developers.google.com/codelabs/openthread-hardware/#3

I installed the wpantund as the tutorial suggested, but when I try to configure the wpantund using the following command:

sudo /usr/local/sbin/wpantund -o Config:NCP:SocketPath /dev/ttyACM0 -o Config:TUN:InterfaceName utun7 -o Daemon:SyslogMask " -info"

I get the following errors:

wpantund[11303]: Starting wpantund 0.08.00d (Nov 14 2019 13:59:00) . . .

wpantund[11303]: State change: "uninitialized" -> "uninitialized:fault"

I am not sure what should I do next. Anyone could give me some advice? Thanks a lot.

are you by any chance running your Linux system  on a virtual machine? To save you some time (back and forth over the weekend, not likely :p) I had a simmilar issue, which i solved by running linux natively. (driver issue from using open source Virtualbox perhaps?) either way, a thread i created earlier: github.com/.../4168.

Also make sure to install all packages, if i remeber correcttly, libreadline didn't install automatically  during isntallation.  I can't remember the exact function of the feature, but nevertheles it seems to be recommended to have it.

Hi,

Thanks for your attention. Yes, I am trying the Thread on the virtual machine via the VirtuBox. I checked the Github page you provided and I think I got the same issue. I will try to run the tutorial on the native Linux machine and see if it helpful. Thank you.

Best,

keep in mind that i never tried the virtualbox extensions because of licensing issues, if you don't have those, it might help to try the extensions out.
