hello @giseleznev, 

please download the complete source code: 

execute the following command in the terminal to download source code from github:
$ repo init -u https://github.com/TinkerBoard2/manifest.git -b linux4.19-rk3399-debian10
$ repo sync

how long should be syncing? I'm on 14% more than 30 minutes, is it ok ?

[i2s, i2c]

OK, I clonned https://github.com/TinkerBoard2/debian, got debian dir. But no build.sh

https://github.com/TinkerBoard2/docker_builder

Seems like this script doesn't work well:
cp: cannot stat '/home/coder/kernel/debian/ubuntu-build-service/packages': No such file or directory
no debian dir here https://github.com/TinkerBoard2/kernel

hello @giseleznev, 

kernel build process instruction for tinker board 2s can be found here: Developer Guide · TinkerBoard/TinkerBoard Wiki (github.com)

 

Hi, currently there are no build.sh and docker-builder-run.sh in the repo, so how can I build 4.19 ? In the attached instruction they are needed.

hello @giseleznev, 

these can be found here, directory is /kernel/sound/soc/rockchip: 

 kernel/sound/soc/rockchip at linux4.19-rk3399-debian10 · TinkerBoard2/kernel · GitHub

Thanks a lot !

Where can I get instructions for kernel compiling ? It doesn't suit for tinker board 2 https://gist.github.com/TinkerTeam/6286550ce70d34f6b3d483cd803da786

analog of rk3288-tinker.dtb is missing

hello @giseleznev, 

PCM5102PW and PCM1804DBR are not supported at the moment

Hi, I'm adding support of this chips. I want to use hifiberry.*c and other files as a reference, can't find them for tinker board 2, just see them in official repo for tinker board (not 2), believe they are different.
Please, could you send me all hifiberry*.c, iqaudio*.c, justboom*.c files from /sound/soc/rockchip/ for tinker board 2.

Thanks a lot !

hi, and what about tinker board2 support. Have you tested it ? Do tinker s snd tinker 2 have any differences regarding audio.

The hifiberry-dacplus-overlay explicitly disables HDMI audio. This is present in /boot/overlays/hifiberry-dacplus-overlay.dts .. To answer my own question.

Also, the hifiberry-dacplus-overlay is meant for the PCM512x instead of the PCM510x . These IC's very similar, but the PCM512x series has an I2C interface, which is probed during boot.. dmesg reveals a lot of these:

[    6.163192] snd-rpi-hifiberry-dacplus sound-ext-card: ASoC: CODEC DAI pcm512x-hifi not registered

Could be this driver doesn't support the old 510x ?

Hello, have you managed to figure it out?

Want to connect pcm5102a to a tinker board 2 too. Is it possible currently ? Should I use any overlays ?

[i2s, i2c]

Hi, team,

I want to connect tinker board 2 with dac PCM5102PW and also adc PCM1804DBR using i2s and i2c

Is i2s and i2c interface supported currently? Can i use alsa over i2s out of the box? Or should I install any overlays?
Thanks!
