Thx Already done it - but kernel won't to compile @WernerDo you know where armbian stores its kernel sources(locally) when using docker? I can't find it under output dir in work directory. Here is my structure: s3b0@lenovo ~/Public/git/lamobo/armbian-current $ tree -L 1 . ├── LICENSE ├── README.md ├── VERSION ├── build.sh ├── cache ├── compile.sh ├── config ├── kernel ├── lib ├── output ├── packages ├── patch ├── unused_patches └── userpatches

Hi Is there a way to set url for kernel sources for build process of armbian? I want to try this kernel: https://github.com/openedev/linux which has - potentially - fix for my problem described here: and here: https://forum.banana-pi.org/t/lcd-module-dsi-rgb-with-touch-and-s070swv20hg-dc16-lcd-panel-mainline-kernel/11172 But i have no idea how to change default url for kernel sources. Ps. I'm using docker to build and have question: where armbian stores its kernel sources(locally) and how to obtain its urls?

I removed panel_power from dts(u-boot and linux) and CONFIG_VIDEO_LCD_POWER="PH12" u-boot defconfig for Lamobo-R1 and you have right, power is fixed according to schematics but panel is still death after u-boot loads kernel (same behavior as you have seen on my youtube video). Still clueless - it must be linux driver but i don't have knowledge to fix it (i know c but don't know anything about linux panel drivers development) Some time ago i talked with owner of this repo https://github.com/wens/dt-overlays/ and he gave me this overlay https://github.com/wens/dt-overlays/blob/master/bpi-m1p-lcd.dts - maybe it will work with your hint implemented (removing of PH12 as panel_power)

It is BPi-R1 (codename is Lamobo R1). Thx - will try it ASAP.

BTW. On old bananian with legacy kernel 3.4 from sunxi this panel works - so it is not its fold(hardware is fine)

Changed - u-boot working fine Changed - backlight works I have problem with this - on our boards there are 4 IO GPIO PINS for LCD PH7,PH8,PH9,PH12(i think so, according to pin definitions that can be found here:https://web.archive.org/web/20210906165454/http://wiki.lemaker.org/BananaPro/Pi:Pin_definition#Banana_Pi_CON2_definition) I've tried to change touch pane definition and I've put there PH8 but result are the same as during my previous tries: Uboot shows loading kernel and when kerenl takes controls i goes like above.

Hi, I have lamobo-r1(A20) with pinout same as bananapi pro and i have LCD display 7" (more info here: https://forum.banana-pi.org/t/lcd-module-dsi-rgb-with-touch-and-s070swv20hg-dc16-lcd-panel-mainline-kernel/11172 ) and i cannot make it work with armbian. The main difference between your display and my is backlight enabler(CONFIG_VIDEO_LCD_BL_EN) which on mine is PH9. I made it work with u-boot but i can't force it to work with linux (you can see it in the link above). Do you have any hints where i can search for help(or even simple hints) that would help me to run it under linux? I've tried to follow your tutorial and i even tried to change pins according to those i have in u-boot configuration(which are working) and nothing - i loosing hope so any help will be appreciated.

Hi there. Is there someone who can guide me with linux driver porting? I have old LCD panel for my bananapi like described here: https://forum.banana-pi.org/t/lcd-module-dsi-rgb-with-touch-and-s070swv20hg-dc16-lcd-panel-mainline-kernel/11172 but i can not make it work with linux. Old bananian has this driver and it is working. I would like to try to port it to mainline but i don't know how to start. I'm skilled user of linux, for few past years i've been using gentoo so i know what is kernel and how to tweak or compile it. I know C on decent level so i think i could made it but i have no clue how to track working driver down and how to port it from 3.4 kernel(this is kernel from bananian image). I manage to add it to u-boot, but all my tries to add it to panel-simple.c driver was unsuccessful. This is back-plate of my panel: https://ibb.co/1zcFpQL
