The UART can be activated. GND, RX and TX are in a non-connected state by default. GND can be easily connected to the ground available on the printed circuit board. Enabling RX and TX require shunting two pins for RX, and two pins for TX, using the diagram below GND RX TX 3.3V (serial connector) [] [] [RX] [TX] [] [] (empty component close to the serial connector) (shunt) (shunt) [] [] [RX'] [TX'] [] []

Hi @amine; the answer here: https://gitlab.freedesktop.org/lima/mesa/issues/73

You are right the blob: 'mali450r5p001rel0linux1fbdevarm64v8a' is the proprietary library executing the GLES operations on the mali 450. The linux GNU/GPL license is not compatible at all. Indeed, we don't have a tutorial; On the framebuffer environement you just have to add the GLES headers on your gcc include directory, and add the 'blob' as a library.

This setup is now working using the mainline kernel (megous 4.14 and the following patch: https://github.com/noblock/sunxi-mali/blob/master/kernel-patches/9902-megous-add-h5-mali.patch). Using the same r5p0 blob: Once you have the kernel, here is the mali kernel module (r5p0): https://github.com/noblock/sunxi-mali Here is the general information: https://bootlin.com/blog/mali-opengl-support-on-allwinner-platforms-with-mainline-linux/

Here are the steps to get a legacy H5 kernel running with Mali r5p0: * Linux kernel from: https://github.com/OrangePiLibra/OrangePi_H5SDK * Here is my legacy kernel generation script: https://pastebin.com/w1b4exzW * Mali kernel module: DX910-SW-99002-r5p0-01rel0 from here: https://developer.arm.com/products/software/mali-drivers/utgard-kernel * Mali kernel patch: https://pastebin.com/VnJgZWZJ (name: DX910-SW-99002-r5p0-01rel0.patch) * Blob: mali450r5p001rel0linux1fbdevarm64v8a * Good benchmark/test utility: glmark2-es2-fb. The blob is a aarch64 one, so we must use a aarch64 linux environment to compile and run glmark2-es2-fb. #script template: #orangepi_h5sdk_dir link to repository: https://github.com/OrangePiLibra/OrangePi_H5SDK yourkernelorangepih5sdkfullpath="<>" f="DX910-SW-99002-r5p0-01rel0";rm -Rf mali_r5p0/;tar xf $f.tgz;(cd $f/;cat $f.patch|patch -p1);mv "$f/" mali_r5p0/; #mali450r5p001rel0linux1fbdevarm64v8a mkdir -p mali_r5p0/driver/src/devicedrv/mali/include/linux/aw/sun50i/; cp orangepi_h5sdk_dir/kernel/modules/gpu/mali450/kernel_mode/driver/src/devicedrv/mali/linux/mali_platform.c mali_r5p0/driver/src/devicedrv/mali/linux/mali_platform.c cp -dpR orangepi_h5sdk_dir/kernel/modules/gpu/mali450/kernel_mode/driver/src/devicedrv/mali/include/linux/aw/platform.h mali_r5p0/driver/src/devicedrv/mali/include/linux/aw/ cp -dpR orangepi_h5sdk_dir/kernel/modules/gpu/mali450/kernel_mode/driver/src/devicedrv/mali/include/linux/aw/config.h mali_r5p0/driver/src/devicedrv/mali/include/linux/aw/ cp -dpR orangepi_h5sdk_dir/kernel/modules/gpu/mali450/kernel_mode/driver/src/devicedrv/mali/include/linux/aw/sun50i/sun50iw2p1.h mali_r5p0/driver/src/devicedrv/mali/include/linux/aw/sun50i/ sed -r -i "s/^(int mali_fb_start = )0(;)$/\10x7f040000\2/; s/^(int mali_fb_size = )0(;)$/\17372800\2/" mali_r5p0/driver/src/devicedrv/mali/common/mali_kernel_core.c; #from: fbset -i #(cd mali_r5p0/driver/src/devicedrv/ump;(make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnueabihf- -j 8 KDIR=${yourkernelorangepih5sdkfullpath} V=1 BUILD=release)) (cd mali_r5p0/driver/src/devicedrv/mali;make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnueabihf- -j 8 KDIR=${yourkernelorangepih5sdkfullpath} V=1 USING_UMP=0 USING_DT=1 BUILD=release)

I just checked the mali blob: mali450r5p001rel0linux1fbdevarm64v8a (fbdev) and this blob is working on the legacy kernel with the proper patches. Nevertheless we may have some stability issues at the current voltage/frequence; Indeed gl-mark2-es-fb crashes around the refract test on my board.
