Raspberry pi

[mattiaswal]

Add support for raspberry pi 4 in normal aarch64 image, as well as a sdcard image for initial deployment.

Supported featureset so far:

• WiFi (builtin)
• USB (can be controlled in ietf-hardware module, but is only seen as one usb port)
• (graphic, may work, drivers and firmware exist but it is untested)

It builds and boots, but I get this output from the CLI at first boot. Is this normal?

admin@rpi4:/> show interfaces 
[   54.650617] ieee80211 phy0: brcmf_cfg80211_get_station: GET STA INFO failed, -52

No interface data retrieved.

admin@rpi4:/> 

On the second boot (plain reboot in between) it works better:

The output from the kernel i have seen (but forgotten) Should not be there. Show interfaces crashing is bad. Will have a look at that, have not seen it. What does the log say?

[mattiaswal]

If i remember correctly you got the output from the kernel on wpa_cli -i wifi0 scan_results

Not much, this is the entire session from login to CLI to reboot:

Nov  4 10:54:37 rpi4 klishd[3313]: user "admin" starting interactive sysrepo session.
Nov  4 10:54:52 rpi4 wpa_supplicant[3219]: wifi0: Failed to initiate sched scan

Nov  4 10:57:29 rpi4 klishd[3313]: user "admin" called RPC /ietf-system:system-restart

Also worth mentioning, it took a good while to get the prompt back when it crashed. I'm guessing up to 10 seconds.

Unable to reproduce, disabled scan (disabled the autoscanning from finit), but my fallback (in yanger) kicked in and started scanning.

Disabled the fallback, and still no crash. I can see the WiFi interface is in state DISCONNECTED (not scanning or anything), when scanning this should be SCANNING or INACTIVE

Amazing work on this, really great to have support integrated in our standard builds! 💪

I'm looking forward to learn more about these cool board packages. Makes things very clean and tidy 😎
