Hello. I change from diet pi to my own compilation of armbian with rt kernel patch (orangepi zero) In dietpi the my python code run perfectly the lcd screen (GPIO) but in armbian the code fail. When I try to install GPIO with : sudo modprobe sunxi-gpio The output is: modprobe: FATAL: Module gpio-sunxi not found in directory /lib/modules/4.13.9-rt1-sunxi Very thanks How I can repair this? pd: I enabled all gpio overlays in armbian-config Also, I founded this, but I dont understand What is proposed here is for all pins or only for the ones set, and if this can work with I2C, Spi, etc... Thanks a lot in advances. nwk

It worked!!! Thanks. Thanks a lot for the advices!!!!

If you see, there it says, orange pi pc....I used this defconfig from buildroot, with some changes to meet the parameters i needed.. I attach the defconfig used. The . config used, is from an armbian which i erased the things i didnt need. also, I used the RT patch provided. The compilation runs good. Thaks a lot in advance. ** One thing maybe. I did not applied the patches for u-boot...maybe that could be the problem???... I use the moment to ask, why does the u-boot need to be patched??. orangepi_pc_defconfig

Hello. I putted the image I got from buildroot on the orange pi, but doesnt boot. I atach the files. any orientation is wellcome. Thanks a lot. images.zip

Hi. I managed to compile it, I did with Buildroot, the sun8i-default, a .config from a previus armbian i was using, and the kernel patches from the build, It has all compile well, but havent tried it yet. I will post when i try it,, hopefully in some hours. Thanks a lot for the answers. nwk

Hello Again. I am triying to compile the OS with the Armbian compilation tool. I have enabled the RT patch (by errasing .desable), but I gen an error: [ error ] ERROR in function compile_kernel [ compilation.sh:339 ] In the compilation.sh, the line 338, is: if [[ ${PIPESTATUS[0]} -ne 0 || ! -f arch/$ARCHITECTURE/boot/$KERNEL_IMAGE_TYPE ]]; then exit_with_error "Kernel was not built" "@host" I dont know what actually this menas. What could it be done to fix this?? Thanks a lot in advance.

Hello. Thanks for the posts, very helpfull For sun8i, there is no 0014 patch (RT). I want to use it for an Orange pi zero SoC (which uses the H2+ (similar to H3 processor)). So is the path the same (i dont think so???), and would it work to download the patch form the RT project page (kernel.org....), and us it??? Thanks in advance.

Hello Igor. Thanks for the reply. Will do.. But, I have read, that this way, Hard RT cannot be done?? Thanks a lot.

Thanks a lot for the reply. In the page https://rt.wiki.kernel.org/index.php/Main_Page There is 3.4-rt patch.... https://www.kernel.org/pub/linux/kernel/projects/rt/3.4/ Isn't that usable with the 3.4.113-sun8i kernel....?? downloading the kernel, using current working armbian .config, putting all the things needed (getting this things from Armbian/build/patch/sun8i-default), then add the RT patch, and compile it. Would this give an RT OS to use with the orange pi zero?. Thanks a lot.

And another thing please... The kernel used for using this patches is this one (https://github.com/orangepi-xunlong/orangepi_h3_linux) ?? Because,I have not been able to find another 3.4.113-sun8i, In that page it says its ok to use for orange pi. Thanks a lot in advance. nwk

Hello. Thanks for your answer Igor. I am trying to patch for RT, to use an Orange pi zero. In the build folder, in build/patch/kernel/, there is the sun8i-default, and the sun8i-dev folders..What is the difference between this 2 (I am kind of neewbie in this). also, why is it necessary to u-boot, and the patches I would need for Orange pi zero are u-boot-sunxi (right?) Thanks a lot in advance.

Hello. Some questions if you please? Where do you get all the patches for the Armbian functionalities, from the armbian build??.. Also, the RT patch you (Chrisk) are providing, is one you created, why not use this one https://rt.wiki.kernel.org/index.php/Main_Page Also. Igor....where do you remove .disable to use this RT-patch its all ready been tested, and from where does it come from from the page i put above? (I ask this, because I need to patch an Orange pi kernel with this RT patch. So I was thinking in including the preempt-RT patch on the patches folder on the Armbian build (which i have started looking not so long ago. My first strategy was to use buildroot, but have problems with all the patches and now desided to use Armbian and patch it with the preempt-RT patch)). Thanks in advance.
