Bug#977702: firmware-brcm80211: brcmfmac43455 on RPi4 causes hostapd to fail silently
Package: firmware-brcm80211
Version: 20200918-1~bop10+1
Severity: normal
Dear Maintainer,
Steps to reproduce:
1. flash latest tested Raspberry Pi 4 image and boot
2. update all packages
3. install hostapd
4. configure the onboard wlan device as an 802.11n AP
Expected results:
AP works
Actual results:
hostapd claims the AP is enabled, but it's actually not
Work-around:
1. apt purge firmware-brcm80211
2. cp /lib/firmware/brcm/brcmfmac43455.* from a current stable Raspbian
install
- this appears to work even despite the fact that
Raspbian is 32-bit
- the driver still throws a warning about a missing
brcmfmac43455-sdio.raspberrypi,4-model-b.txt file, but
this file is not included with stable Raspbian, and its absence
doesn't appear to cause any problems beyond the warning
The brcmfmac43455 firmware in firmware-brcm80211 appears to be much
older than what Raspbian stable is currently shipping
