Hello, I got I finally working. There are some changes to be done in the device tree to make sun4i-drm and lima work with LCD-Panels on BananaPi / BananaPro. Short version: create a panel in device tree and connect it to the correct driver. Here's what I did: 1. Start compilation with ./compile.sh CREATE_PATCHES=yes BOARD=bananapipro INSTALL_HEADERS=yes 2. If asked to apply changes modify u-boot-config: nano /build/cache/sources/v2020.04/configs/Bananapro_defconfig add #5" RGB LCD CONFIG_VIDEO_LCD_MODE="x:800,y:480,depth:24,pclk_khz:30000,le:40,ri:40,up:29,lo

Hello Werner, Thank you for your propt reply. The output of armbianmonitor -u has been located here: http://ix.io/2qTs The device tree has been changed according this description (last post): I changed the device tree to integrate the axp209 PMIC driver according to the configuration given in BananaPi's device tree and added SPDIF-Support. So please don't mind about messages which don't appear on usual BananaPro images. regards

Hello, Im currently working on making lima run with an original 5"-LCD on BananaPro. My problem is to make it work with the sun4i-drm driver. At boot everything works fine and the display shows u-boot and kernel outputs but when the kernel starts the sun4i-drm driver the display freezes and turns white after some seconds. dmesg says: [ 11.178221] sun4i-drm display-engine: bound 1e00000.display-frontend (ops 0xc09986d4) [ 11.178361] sun4i-drm display-engine: bound 1e20000.display-frontend (ops 0xc09986d4) [ 11.178858] sun4i-drm display-engine: bound 1e60000.displa

I got lima working on BananaPro by adding following contents to build/cache/sources/u-boot/v20XX.XX/arch/arm/dts/sun7i-a20-bananapro.dts : Enable HDMI: Enable display engine: Change build/cache/sources/linux-mainline/orange-pi-5.XX/arch/arm/boot/dts/sun7i-a20-bananapro.dts accordingly. Then compile the mesa driver like this: nano /etc/apt/sources.list // uncomment #src apt update apt build-dep -y mesa apt install -y git g++ build-essential pkg-config apt install -y libx11-dev libgl1-mesa-dev apt install -y valgri

lsmod shows sun4idrm and as far as i can say all devices needed are where they should be. On that base Lima can be run with basic functionality. It does not work like a charm (not all GL-Drives do work) but lima is able to run kodi.

I just built the lastest armbian sources for BananaPi minimal, which is version Armbian_20.08.0-trunk_Bananapi_buster_current_5.4.44_minimal and startet ist on my BananaPro. After that I got mesa running doing this: ... and kodi on X11 started properly. Got into Kodi->Systeminformation. There it says lima driver is used. This failed on various BananaPro images before. The question is how to integrate that into a build script. Furthermore there seem to be some differences between the image configuration of BananaPi and BananaPro although the only differences are

Finally got it to work building mesa on my own on a recent BananaPi image But it would be very cool if the sun4i-drm driver was fixed in BananaPro images. Can you please take care of that, Igor? I'll help you as far as I can and will provide further information from my test machine.

On the BananaPi image startx says: Indeed /usr/lib/arm-linux-gnueabihf/dri/ contains various *_dri.so files but none called sun4i-drm. Any suggestions what to do?

Thanks a lot for your replies! I still have the problem lima does not work properly. Module sun4i-drm, which is needed for lima, is avaliable via modprobe (at least ist gives no error message), but seems not to be loaded either. lsmod does not show it. I don't exactly know what is wrong but it seems there is a problem with the compiled driver. When I look into /lib/modules/5.4.44-sunxi/kernel/drivers/gpu/drm/sun4i/ there is just a file called sun6i_mipi_dsi.ko. What has sun6i todo with sun4i? The GPU is a different one (Power VR SGX 544 instead of Mali 400). The only thing I've fou

Hello guys, I've been playing around with the build-in lima drivers but didn't get it to work on BananaPro using Armbian_20.02.1_Bananapipro_buster_current_5.4.20_desktop image. I installed drivers armsoc, modesetting, fbdev from debian buster repos but "Xorg -configure" fails. /var/log/Xorg.0.log says: and and generated xorg.conf: Any suggestions what I am doing wrong? regards

Hello there, I'm new to this Forum, so please I been trying to run Kodi as standalone music station with Buster minimal and Kodi 17 on it. This system boots very quick and I've been quite happy when I got kodi starting successfully, but it's very slow. It takes several seconds to switch from one menu item to the next. Next I tried to speed up the graphics using this instructions https://forum.armbian.com/topic/1420-opengl-on-mali-gpu-bananapi-orangepi-pc-etc/ http://wiki.lemaker.org/BananaPro/Pi:GPU But failed with xorg saying: /etc/X11/xorg.conf:
