Banana Pi BPI-M2 Zero new image : Ubuntu 19.10 Eoan Ermine Kernel 5.3.5

@igorpec It’s the last commit over here, based on the upstream sunxi-next tree:

@avaf, can you please share your sources?

I’m quite the beginner here, you’ve already done the heavy lifting, and it would benefit everybody. I can keep going on to see whether I can replicate your work, hunt down patches from jernejsk, etc. etc. Or you can just share your branch on github. Much easier for everyone, and creates a much bigger impact! And it would honour the GPL too.

I will cleanup the sources and push it to github (kernel tree is not with git versioning). This can take some time for me.

Kernel 5.3.18 is rock-solid on BPI M2Z and BPI Ultra with the following working (both boards):

  • HDMI
  • HDMI sound
  • Analog sound (M2U)
  • i2c
  • cedrus
  • mali

Meanwhile i will add some new functions to the htop 2.2.2 for the armhf (branch armhf):

Try any latest Mainline release from 5.3 and above, it has good Lima support but for lima to work you will need the latest Mesa package for the distro you want to test it on.

Lima have good support on Wayland so you can try KDE with Wayland if your distro have KDE

Lima should work out of the box only when you have the latest mesa installed and also you dont need fbturbo drivers which is used for software acceleration.

There is no X11 support in Lima. So try Wayland.

All the best.

Okay, sounds great! Hope to hear from you soon, I’m just starting a week of holidays, so I have a bit of time on my hands :slight_smile: MESSAGE EDITED BECAUSE I FIXED THE BLUETOOTH THING (KERNEL CONFIG ISSUE).

I did succeed in replicating most of your work on the device tree. I do get a hdmi sound device now, I’ve added cpu frequencies for 120, 240 and 480 MHz, I’ve added the code for the display engine, I tried to add some code for bluetooth. However, I appear to be hitting a couple of walls. Can you perhaps lend me a hand with hdmi sound out? Patches are on github, on top of sunxi-next, although I only tested the device tree on armbian 5.5:

Regarding hdmi sound out, can you please check whether I missed anything obvious? I had expected that the following three commits should have done it, but I get no sound if I aplay one of the .wavs in Ubuntu, and it seems fishy to me that alsamixer does not show any controls, although it recognises the device:

@spikerguy Thanks for all the suggestions. I’m now on kernel 5.5 and Ubuntu 20.04.

This must be a complete newbie question, but how do I even find which mesa package contains the lima drivers? Coming from Slackware, Ubuntu package management has quite the steep learning curve. I’m not even sure whether mesa was built with lima support, and even if it was, I wouldn’t know how to find out on Ubuntu. But I can’t seem to find anything lima related:

dpkg -S *lima*
linux-image-dev-sunxi: /lib/modules/5.5.4-sunxi/kernel/drivers/gpu/drm/lima/lima.ko
linux-libc-dev:armhf: /usr/include/drm/lima_drm.h
linux-image-dev-sunxi: /lib/modules/5.5.4-sunxi/kernel/drivers/gpu/drm/lima

I don’t know how to query all packages in a repository to find which one contains lima. I’m sure that Focal Fossa’s mesa version is sufficiently new for lima, but I’m starting to fear that it isn’t packaged… Any pointers are welcome!

*** EDIT *** I have this file, though: /usr/lib/arm-linux-gnueabihf/dri/

@spikerguy @igorpec

Ok, lima does work, on the armbian kernel. Tested with kmscube and weston-launch.

@igorpec, I have a strange bluetooth issue. I can’t get it to work on the armbian kernel, and I don’t know why. Here are the changes that I made:

/lib/firmware/brcm/BCM43430A1.hcd -> /lib/firmware/ap6212/bcm43438a1.hcd

(I think I can just link that last one to /lib/firmware/ap6212/nvram.txt)

I’ve compiled my own kernel based on sunxi-next, and there bluetooth works without further configuration. On the armbian kernel, basically nothings happens, not even when I manually load the hci_uart module. Also, the bluetooth rfkill device doesn’t show up, whereas with my own kernel config, it does. (Conversely, I can’t get lima to work with my sunxi-next config).

@igorpec, if you have any suggestions for getting bluetooth working, I’d be very happy to hear them! I would love to get the above changes in armbian as well…

Finally, I can play a sound file with aplay, but I can’t hear it… Any suggestions more than welcome!

If i recall correctly i could only play wav files with 16-bit channels (not 8-bit)

Maybe you can get a clue reading this thread:

I don’t see anything missing but the code for hdmi out on kernel 5.5 is significantly different from 5.3

I’ve pushed my work to kernel 5.6.y here:

You can add your fixes and patches. Feel free.

Thanks! What did you use as base? 5.6-rc3? And from mainline or sunxi-next?

Mainline Kernel 5.6-rc3. Please apply your sunxi-next changes, there are still some necessary fixes.

OK - I’m finally getting somewhere.

  1. lima just works, if you remember to test kmscube as root, because otherwise kmscube will use llvm instead of lima.
  2. Audio out over hdmi works on Armbian, given sufficient patches to the devicetree. I finally got that to work, with the armbian kernel, but not on sunxi-next or on the orangepi branch of megous . Apparently armbian adds some patches that I haven’t located upstream.
  3. Somehow, my kernel config just loads bluetooth, wheres the armbian sunxi-current and sunxi-dev kernel configs don’t do anything for bluetooth. Very strange…

@igorpec, I’ve added a couple of dts patches for the bananapi, if you’re interested! Or should I try to upstream these to sunxi-devel? See here:

I am. Perhaps just make a PR?

Share your working kernel config. I am confused as to which kernel you are working on.

I don’t see the patches you are applying and in which kernel (only for the Armbian), so I can try or find some workaround. All your changes are on your github kernel tree?

I just send you one. I hope. Never did this before, so I hope it all works. EDIT: Definitely didn’t work, hahaha! EDIT2: I think I succeeded now.

@avafinger - config.gz (27,6 KB)

I’m now working on top of the kernel used in Armbian, so megous, branch 5.5, with a couple of patches that, among other things, enable hdmi audio out. I’m hoping to figure out how to change the armbian kernel config so that it loads bluetooth the way it should.

Yeah, it looks fine and doesn’t break building. Thanks!

Kernel 5.6-rc3 is up and running.

HDMI sound out works!

@avaf nice going there!

@igorpec I sent another two pull request, which should fix bluetooth on the BananaPi M2 Zero, and possibly a few other devices.

For now, I’m fine with using the Armbian tree as it is. But do you know whether “megous” is upstreaming his work on the orangepi kernel branches that armbian uses? And if so, do you think it would be an idea to submit the BananaPi M2 Zero devicetree patches to him?

Final fun fact, I installed lxde and xorg, and it was able to load the right drivers for a hardware-accelerated desktop on lima! Not bad at all! I might still persuade this little device to act as a dvd player after all.

We have lime in the kernel for two years, since introduction of 4.19.y :slight_smile:

Things needs a lot of time before getting to mainline. Some stuff never arrives.

Hi! I’m having issues getting any connectivity. Both ethernet and wifi. Using bpi-m2z-8GB-sd-ubuntu_eoan_kernel_fbdev_5.3.11.img
