I am running a headless Bananapipro server that acts as an AP. Recently I found that its WiFi net was gone. In the log I found a crash of brcm: Dec 19 02:40:14 localhost kernel: [3919907.052132] ieee80211 phy0: brcmf_fw_crashed: Firmware has halted or crashed Dec 19 02:40:15 localhost kernel: [3919908.004319] ieee80211 phy0: brcmf_fil_cmd_data: bus is down. we have nothing to do.

I shall also note that there are at least once a day messages like this in the log: Dec 19 22:36:32 localhost kernel: [20143.706800] ieee80211 phy0: brcmf_psm_watchdog_notify: PSM's watchdog has fired! The system is: uname -a Linux bananapipro2 6.6.44-current-sunxi #1 SMP Sat Aug 3 06:54:42 UTC 2024 armv7l GNU/Linux Are there any hints how to proceed with this issue? Many thanks, Thomas
