initramfs-wifi.hook for Raspberry Pi 4
Closed this issue · 7 comments
Hello @unixabg
If it possible modify initramfs-wifi.hook for Raspberry Pi 4?
With default options: "brcmfmac brcmutil cfg80211 rfkill" my Rpi 4 doesn't work...
Thx =)
Greetings,
So what I can say is that 0000-experimental-initramfs-wifi.hook has some issues. Please know that I will examine, but I am not sponsored for this project and only get to work on in my spare time. However, I do think that it should be possible to activate the wlan0 networking for remote unlock. The 0000-optional-sys-wifi.hook is in good order and operates as expected.

Hi @unixabg thx for your answer
But I can do myself, Can You help me only with wifi module:
Which wifi drivers I must to use, then start My Rpi4B, default doesn't work
_INITRAMFS_WIFI_DRIVERS='brcmfmac brcmutil cfg80211 rfkill'
Rpi4B has BCM2711, but I don't know default wifi chipset
Can you help me?
When my Rpi4 boot up I have next error;
brfmac direct firmware load brcm/brcmfmac43455-sdio failed with error -2

Greetings,
So the issue was that the firmware for the wifi was not included in the initramfs. Also on boot it needs just a small sleep to allow the wlan0 be ready for operations, see commit 7ecfe01 . I tested both rpi3b+ and rpi4 in which both unlock over wlan0. Commit f807abf added additional example information to unlock over wifi. Please test and let me know if now working for you.
