Bluetooth(AP6256) with kernel 6.0.11 dose not work?

swordow · December 6, 2022

Hi guys,

I am building armbian image for rockpi4b+ and its kernel is 6.0.11(edge version) and the bluetooth failed start up. If anyone knows what kernel 6.0.11 did that cause the problem:

Yeap. I also tried the 5.15kernel(armbian current version), the same issue.

Igor · December 7, 2022

Worth trying older armbian-firmware package. Perhaps changes in https://github.com/armbian/firmware break it ?

swordow · December 7, 2022

@Igor

The firmware from https://github.com/armbian/firmware (which is built at 2017) does not work.

Also the firmware from https://gitlab.manjaro.org/manjaro-arm/packages/community/ap6256-firmware (which is built in 2020) does not work

The weird thing is that using kernel 5.15.y (armbian current version) also does not work...

I dont know if the kernel 5.10 would make it work...

em... I tested the armbian image(https://fi.mirror.armbian.de/archive/rockpi-4b/archive/Armbian_21.08.1_Rockpi-4b_bullseye_current_5.10.60.img.xz.txt) in rockpi 4b+ roughly, it works:

Can you test WiFi 5G?
I have kernal panic in it, this one of reason why i go to Ubuntu
Thank you in advance.

Test kernel 5.15.75, bluetooh failed to start.

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/diff/?id=v5.15.75&id2=v5.15.74&dt=2

from kernel 5.15.74 to 5.15.75, there are some bluetooh related patches:

...
-rw-r--r--	drivers/bluetooth/btintel.c	17	
-rw-r--r--	drivers/bluetooth/btusb.c	14	
-rw-r--r--	drivers/bluetooth/hci_ldisc.c	7	
-rw-r--r--	drivers/bluetooth/hci_serdev.c	10	
...
-rw-r--r--	net/bluetooth/hci_core.c	34	
-rw-r--r--	net/bluetooth/hci_sysfs.c	3	
-rw-r--r--	net/bluetooth/l2cap_core.c	17	
-rw-r--r--	net/bluetooth/rfcomm/sock.c	3	
....

Maybe some of them break the bluetooth or maybe other uart related drivers(8250 etc) patches break it...

Great bisect @swordow-- any indications on why those upstream changes break it?

possibly, some change has to be done in the DT to accommodate.

does 6.1 work? maybe said change is already done.

Reverting the changes from upstream would be bad for other boards in the family ofc
