Hm, let me look. We added back some dtbo files to the kernel that we had removed, but that shouldn't have affected the bluetooth functionality, but you're right, I can reproduce it here. I didn't re-check things after we added the dtbos back, but this was definitely working previously.

I went down a rabbit hole a week ago trying to solve it and came across this, https://github.com/Re4son/kalipi-firmware/releases/tag/20211127kali but I am not sure how that repo and kali itself are connected? I am not a programmer or kernel expert so I am not sure. But i thought the BCM43436 might have had something to do with Bluetooth? At least the date this was added seemed to be about the time Bluetooth on my RPi4 broke? But as I have said many times, I'm not sure.

No, that's the wireless firmware for the wireless device on the rpi zero 2 w. The bluetooth firmware comes from the bluez-firmware package.

Curious as to whether or not this is going to get resolved or should I just assume Kali and Bluetooth are a no go going forward?

The fix is to

sudo sed -I 's/ttyAMA0/serial0/g' /boot/cmdline.txt

echo 'dtparam=krnbt=on' | sudo tee -a /boot/config.txt

then reboot

The other option would be to downgrade the boot loader package (kalipi-bootloader) to an older version and then apt-mark hold that version so it doesn't upgrade. They changed the serial device on us in it.

It will be in the next release which should be out soon. This fell through the cracks as I was on vacation when the bug report came in.

I tried your fix and then tried upgrading kalipi-kernel from 5.4.83-20210516 to the (latest) 5.4.83-20211204 but it errors. Let me know if I you want me to post the output from the sudo apt get upgrade kalipi-kernel. It is quite long.

Seems like I need to keep my apt-mark in place for kalipi-bootloader, kalipi-kernel, kalipi-kernel-headers and kalipi-re4son-firmware

Please do show the errors, I have not run into any - which fix did you try exactly? You should either do the sed and tee, OR downgrade boot loader, not both.

Here is exactly what I did,
sudo sed -I 's/ttyAMA0/serial0/g' /boot/cmdline.txt
echo 'dtparam=krnbt=on' | sudo tee -a /boot/config.txt

then rebooted.

After reboot, I did
kali@pi-kali:~$ sudo apt install kalipi-kernel

As a quick workaround, try rm-ing that file - /boot/overlays/dwc2.dtbo - I'll have to get with re4son to figure out why that diversion isn't in place to cause the error.

Ok, I rm'ed that file and get an error on another one.

./boot/overlays/gpio-ir.dtbo

Should I just keep rm'ing them until it works?

Yes, unfortunately. Is this a 2021.4 install that you are upgrading? I didn't think there was an upgrade after 2021.4, so is it a 2021.3 image that you started from so I can reproduce the issue here? (also please note down all of the dtbos that you need to remove)

Yes. I believe it was a 2021.3 image that I started from. Would this work if I started from a 2021.4 image? I think I can try that. Just want to keep all my settings if you know what I mean.

The bluetooth will still need the two commands above, it's fine to keep just rm-ing the files (alternatively, if you don't care enough... just rm -rf /boot/overlays)

Thanks for all your help. I went with the nuclear option of 'rm -rf /boot/overlays' and it worked. You can re-close this ticket.

I'll try switching to a 2021.4 base image. Any idea when to expect the 2022.1 image?
