Hello all,
we're working on NVidia Jetson TX2-based product. [1] It run's a Yocto-based distribution with meta-tegra as BSP layer. [2] meta-tegra is based on the official nvidia-provided BSP called L4T (Linux for Tegra), which is available for Ubuntu only. It uses Linux kernel 4.9.
For improved roaming, we would like to replace wpa_supplicant with iwd.
We know full iwd support is only given at Linux kernel 4.20+, but we hoped we can get it working with a reduced feature set on our existing 4.9. That is, we don't need infrastructure or enterprise mode, WPA-PSK is enough for now.
iwd 1.9 can find an adapter, but it doesn't find (or create?) a device.
```

```
When I have the systemd unit invoke `iwd` with the `-d` option, the following gets printed on my kernel log:
```
[76240.009468] couldn't register the net device [wlan0], err -17
```
The systemd journal contains the following:
```

```
Are we totally out of luck with kernel 4.9? As said, WPA-PSK would currently be enough for us.
Thank you!

Hi Manuel,
By default iwd wants to create and destroy interfaces on the phy, but
our driver is probably brcmfmac, which doesn't allow this with its
"primary" interface wlan0.
Have you tried running iwd with UseDefaultInterface=true in
/etc/iwd/main.conf, or adding --interfaces wlan0 to the iwd command?
Kind regards,
Alvin

Hi Alvin,
what shall I say, your hint worked like a charm!
I can now connect to my access point just fine. Thank you a lot!
If someone happens to find this through some search engine, here's some more info I picked up, partly on irc://freenode/#iwd:
* When iwd is invoked with '--interfaces wlan0', then UseDefaultInterface is set automatically
* The driver my system is using ("bcmsdh_sdmmc") has the same issue as the "brcmfmac" mainline driver, which, because of its issues, got set onto a blacklist. Then these --interfaces/UseDefaultInterface settings should not be necessary. But because my "bcmsdh_sdmmc" driver seems to be an out-of-tree one and goes by a different, the blacklist didn't apply.
Again, thank you a lot, Alvin!
Have a nice day everyone.
Manuel
