Unable to make WiFi or Bluetooth work

[Necktwi]

Your Gentoo RPi3 image is working great but when I built the Gentoo for my RPi3B with musl, install your overlay, build the kernel with https://github.com/sakaki-/gentoo-on-rpi3-64bit/blob/master/configs/bcmrpi3_defconfig-bis and merge the firmware: sys-firmware/brcm43430-firmware, sys-firmware/bcm4340a1-firmware, net-wireless/rpi3-bluetooth, I couldn't get the bluetooth or wifi working. In dmesg, I see

...
[    9.700477] mmc1: error -110 whilst initialising SDIO card
[   11.030493] mmc1: error -110 whilst initialising SDIO card

Thank you for your work!

Hi @Necktwi,
have you tried it with an actual kernel + module set (rather than a kernel built from the .config), along with your userland?
Best, sakaki

[Necktwi]

My Gentoo build is a headless server. Yeah, I tried with your kernel + module set. I got some disappointing dmesg that I exactly don't remember. I shall try them once again and let you know the exact dmesg.

[Necktwi]

Now I remember, I use btrfs root. since your kernel don't have btrfs compiled in, I couldn't boot it on.

Re btrfs root, please see comment here.
Thanks, sakaki

[Necktwi]

using the latest kernel with BTRFS support didn't fix the issue. Can you build and test the complete gentoorpi image with the latest kernel? I know its foolish to fix this issue with trial and error method instead of finding the root cause but fixing it with just one more try is rather tempting.

Please see my response here.
Best, sakaki

Actual kernel+module+firmware+overlay got wifi and bluetooth to work. But merging sys-kernel/bcmrpi3-kernel-bis-bin or sys-firmware/bcm4340a1-firmware or sys-firmware/brcm43430-firmware or sys-boot/rpi3-64bit-firmware broken the WiFi and Bluetooth.

[sakaki-]

Odd. Are you on profile 17.0 or 17.1?
Strike that - 17.1 not yet in the wild for arm64 ^-^
Those packages are merged in the actual image build though, so it is strange that they fail for you.

[Necktwi]

I'm very sorry; It seems there's a problem with my pi. WiFi works when I power it on after a long gap. An immediate reboot is giving the mmc1 error. Whenever I burn some image onto sd card the wifi starts working. Its all because I am giving rest for the pi while I am writing the image. Last night when I checked that WiFi not working, I have shut down the RPi, rested it all night and checked for the error in the morning; it's gone!

30 Oct 2020: sadly, due legal obligations arising from a recent change in my 'real world' job, I must announce I am standing down as maintainer of this project with immediate effect. For the meantime, I will leave the repo up (for historical interest, and since the ebuilds etc. may be of use for others looking to take forward Gentoo on 64-bit RPi systems); however, there will be no further updates to the underlying binhost etc., nor will I be accepting / actioning further pull requests or bug reports from this point. Email requests for support will also have to be politely declined, so, please treat this as an effective EOL notice.

For further details, please see my post here.

Many thanks for your interest in this project!

With sincere apologies, sakaki ><
