  1. thanks a lot i will try to get it working - had errors before but didn´t use the rockchip repo before. so thanks for this
  2. quite short answer so no special magic u use ? some guidance you can give?
  3. Hello i modified armbian build script to get board images with 32bit userland and 64bit kernel. most time i´m using the rockpi4b board. because of the 32bit userland i only get the armhf package (tinkerboard) but they only suppoert t76x mali . is there a way you can provide a t86x package for the 32bit userland?! or how can i make it myself?
  4. hello. first i want to say thank you to every armbian supporter and the hole team. thanks for providing this nice project and your work. i did some work for adding an external sound card - the audioinjector pi stereo, which is based on a wm8731. i used the radxa rockpi4(b) board based on the rk3399. i choose this board because of pinout header is nearly the same as the one you find on raspberrys. so adding/ using raspberry Hats won´t be too hart in this case. this will also work with radxa kernel https://github.com/verplant23/kernel so there shouldn´t be any troubles porting it to armbian legacy. i´m not a coder and i don´t know about linux that much. for most things this was try and error of code snippets + lot´s of time. i tried diffrent ways and there are diffrent ways how thing can be get to work - for sure you guys could make things work better because there are still errors while dmesg. i used 20.05 dev kernel but basicly this also work on master or current. please post what you think of or how to improve. install debs or build your own by adding userpatch from https://github.com/verplant23/armbian_patch.git after installing / compiling follow up the armbian docs and add i2c7 by adding overlays=i2c7 to your /boot/armbianEnv.txt i wasn´t able to use armbian-add-overlay. because error told me that i don´t use the correct device... you can use the dtbo inside repo. it was build with the radxa kernel repo (link above). you can find dts inside. add the folder /boot/overlay-user/ and copy audioinjector-wm8731-audio.dtbo inside follow up the armbian docs and add user_overlays=audioinjector-wm8731-audio to your /boot/armbianEnv.txt after reboot cat /proc/asound/cards should show up the card dmesg will show some error: audioinjector-stereo sound-ext-card: snd_soc_register_card failed (-517) but since dmesg | grep i2s will show audioinjector-stereo sound-ext-card: wm8731-hifi <-> ff890000.i2s mapping ok the device should work. when getting no sound go to alsamixer and check the mute cases especially Item: Output Mixer HiFi is not muted you can make it sound-card-0 by default sudo nano /etc/modprobe.d/alsa.conf should be something like alias snd-card-0 wm8731-hifi alias snd-card-0 snd_soc_audioinjector_pi_soundcard alias snd-card-0 snd_soc_simple_card options snd slots=,hdmisound,rockchiprk3399,snd_soc_audio_graph_card make sound-card-0 default device sudo nano /etc/asound.conf defaults.pcm.card 0 defaults.ctl.card 0 have fun and keep healthy
  5. Hello Marko Buršič there are some explaination on the page u linked: GPIO 4 D 5 = 157 4*32 + 3*8 + 5 = 157 i don´t know what "0xae" stands for but it could be something like pull up/down /activ low/high so wenn you see something like csgpio = <&gpio1 21 1 0xae> on rk3399 it would call translated to GPIO Number 1*32 + 2*8 + 5 = 53 32 + 16 + 5 = 53 32 + 21 = 53 GPIO 1 C 5 = 53 but on the 40 Pin Header i can't find a pin number corrospondending to GPIO number 53. so maybe you would like to call ?! Pin# GPIO Function1 GPIO number 24 GP1B2 SPI1_CSn 42 you would write something like ( whatever 0xae mean) csgpio = <&gpio1 10 1 0xae>; 1*32 + 1*8 + 2 = 42 32 + 8 + 2 = 42 32 + 10 = 42 GPIO 1 B 2 = 42 but i´m just guessing
