Great work by the Kernel Dev @tsys
The updated kernel is released and sound is stable now.

Keep up the good work.
Thanks.

I checked out your git repo and want to give it a shot on the default debian. What .config did you use?

There is a pinebook_pro_defconfig you can use with
Code:
make pinebook_pro_defconfig

Thank you tsys and DrYak. I built the kernel (and device tree) with DrYak's .config file. When booting, the screen remains black. Perhaps I would see some logs on the serial console - but I don't have one.

Could I see your extlinux/extlinux.conf?

Here are the current cmdline parameters that Manjaro boots with:
Code:
# cat /proc/cmdline
console=ttyS2,1500000n8 root=PARTUUID=937d1032-01 rw rootwait bootsplash.bootfile=bootsplash-themes/manjaro/bootsplash append video=eDP-1:1920x1080@60 ramdisk_size=10M earlycon=uart8250,mmio32,0xff1a0000

there  are indeed parameters for video and for serial console/early console.


And attached is the dtb currently provided:

(In my limited experience, it's easier to decompiled dtb into dts using dtc and compare these outputs)

Following up on the no display be aware that the pinebook_pro_defconfig is a distro-like config and is highy modular. The display will not come up until the rootfs (or initrd) comes up and the appropriate drm modules are loaded.

Thus if you didn't copy the modules to the rootfs (or your kernel command-line doesn't mount the rootfs correclty) then the display will never come up...

(if you did copy the modules then be patient, it takes a long time to initialize the kernel... the log messages make it look like CPU0 is clocked *very* slowly when u-boot hands it over)

As of now Bluetooth is working, too.

It does still need hciattach

Code:
hciattach /dev/ttyS0 bcm43xx 1500000 flow nosleep

and native support though hci_uart should be possible. However you can now connect your favourite bluetooth-enabled device to the Pinebook Pro.

Thanks a lot tsys for your continued work on this! Smile

Thank you so much for this fix!!!

I recently installed the Manjaro P3 image.

I can't see 5ghz networks.
