brcmfmac crashes in AP mode

[moham96]

Hi,
Trying to make the wifi chip to work in ap fails and the driver/firmware seems to fail at setting the beacon settings

running hostapd gives this error:

wlan0: interface state UNINITIALIZED->COUNTRY_UPDATE 
Failed to set beacon parameters 
wlan0: Could not connect to kernel driver

and the driver threw this in the kernel log

ieee80211 phy0: brcmf_cfg80211_start_ap: Beacon Interval Set Error, -52

Is this issue specific to the wifi chips on the MacBook air (driver/firmware issue) or is this a general issue in the brcmfmac and should be reported to the brcmfmac maintainers?

Regards

I'm having the same -52 error simply by using a WiFi network:

Is this issue specific to the wifi chips on the MacBook air (driver/firmware issue)

I was trying to set up hostapd on my Mac Mini M1 the other day and:

• hostapd properly set the AP up: iwconfig & friends look ok.
• the AP was broadcasted and visible from my other devices
• but the AP was NOT joinable: e.g on a macOS device joining process starts, asks for passphrase, then the client bails out and errors with a generic message.

I am unsure whether the AP was actually joined at the link level but immediately failed to communicate or if it failed earlier. IIRC logs showed an immediate "client connected" then "client disconnected". DHCP is never reached out to, that's for sure.

Can't recall if I had any of the errors above, I will look for them next time I have a chance to try.
