Allwinner A64 LVDS overlay

[Zaltora]

Hello, i want to make work a LVDS screen on a Olimex board using Armbian.

I have take a look  on this topic to get clues : lvds_a20

 

Informations:

Armbian: Custom build with 5.10 kernel.  ( KERNEL_ONLY=no KERNEL_CONFIGURE=no BUILD_MINIMAL=yes BUILD_DESKTOP=no  BOARD=lime-a64 BRANCH=current RELEASE=buster)

Board: Lime-A64

Ethernet : Disable with jumper (lvds and ethernet share some pin )

 

Resources:

- Overlay from other board : lcd-olinuxino-15.6.dts

- http://linux-sunxi.org/Linux_mainlining_effort

 

Status:

 

I rewrote the "overlay" with the configurations of my display and my board ( Attached ) with, i guess, misstakes

I have enable some kernel modules for use LVDS in "/etc/modules":

lvds-codec
panel-lvds

 

I have enable the overlay with this command:

armbian-add-overlay lvds-a64.dts

 

 

After reboot, lvds not seem activated and the second overlay i wrote (for CAN bus) is disable.

dmesg | grep lvds
[    5.516865] Modules linked in: cpufreq_dt mcp251x can_dev panel_lvds lvds_codec micrel pinctrl_axp209 dwmac_sun8i mdio_mux

 

 

Someone got idea what is my misstake in the overlay ? Or the LVDS activates otherwise ?  How can I check that the LVDS installation is working properly?

Do you think LVDS can work with A64 ?

 

 

lvds-a64.dts
