hanni76 Posted June 23, 2017 Share Posted June 23, 2017 Hello guys I have a question regarding H3 overlays. I see that during build "overlay" folder is created in arch/arm/boot/dts and H3 overlays are copied there. Can you point, please, where build framework takes those file from and how to customize this ? The goal here is to add an extra overlay. I see that the structure is very similar to https://github.com/armbian/sunxi-DT-overlays but I can't find in build scripts if you copy files from there or any other repository. Thanks.

It's not customizable in a simple way (without adding or editing kernel patches). It should be possible to compile or copy precompiled overlays in "customize-image.sh" Link to comment Share on other sites More sharing options...
hanni76 Posted June 23, 2017 Author Share Posted June 23, 2017 Thank you That means I can copy this patch to "userpatches" and modify it, correct ? Link to comment Share on other sites More sharing options...

hanni76 Posted June 26, 2017 Author Share Posted June 26, 2017 Quote Hello, zador.blood.stained, one more question: how can I add my overlay into armbianEnv.txt file in a resulting image automatically? Link to comment Share on other sites More sharing options...
hanni76 Posted June 26, 2017 Author Share Posted June 26, 2017 and 1 more question: what is meaning of line MODULES="8189es #w1-sunxi #w1-gpio #w1-therm #gc2035 #vfe_v4l2 #sunxi-cir" in the file config/boards/*.conf ? Link to comment Share on other sites More sharing options...

List of entries added to /etc/modules, in this case - for the default (legacy) kernel. Link to comment Share on other sites More sharing options...

hanni76 Posted June 27, 2017 Author Share Posted June 27, 2017 Hi zador.blood.stained can you explain please how to add an extra module (i.e. wm8731 codec) module in legacy kernel ? What file should be copied into userpatches and modified ? Thanks Link to comment Share on other sites More sharing options...

Sorry, activating third party hardware on legacy kernel is complicated since these drivers need palform data to specify I2C/SPI bus and audio routing parameters. As far as I know there is no ready to use solution for this or most of the other drivers. Link to comment Share on other sites More sharing options...
hanni76 Posted June 27, 2017 Author Share Posted June 27, 2017 so we cannot use built-in Soc codecs (/sound/soc/codecs) in legacy kernel ? Link to comment Share on other sites More sharing options...
zador.blood.stained Posted June 27, 2017 Share Posted June 27, 2017 I didn't say that it is impossible, but, as I said, it's not something that can be done without patching and recomplining kernel as far as I know. Link to comment Share on other sites More sharing options...
