Title: Issues with LVDS Display Configuration on AIO-3399J (v1.3) [Print This Page] Author: trinoctial Time: 11/28/2024 14:58 Title: Issues with LVDS Display Configuration on AIO-3399J (v1.3) I¡¯m new to working with the AIO-3399J and recently received a v1.3 model after working with the v12 for a while. I¡¯ve managed to get everything set up, but I¡¯m running into an issue with the LVDS display. On the v12, I was able to get dual-LVDS working perfectly after configuring the kernel, but with the v1.3 model, the screen stays black, and only the HDMI output works.
I¡¯ve tried using the same kernel configuration from the v12 board, but I¡¯m not sure if there¡¯s a new setting or patch required for the v1.3. Has anyone here encountered a similar issue? Are there any changes to the device tree or kernel options for dual-LVDS support on the v1.3 version?
Any help would be greatly appreciated! geometry dash

It is lcd power problem probably.
This part solved issue for me:
panel@0 {
........
enable-gpios = <&gpio1 4 GPIO_ACTIVE_HIGH>; //lcd power enable
enable-tc-gpios = <&gpio3 16 GPIO_ACTIVE_HIGH>; //tc358775 power enable
reset-gpios = <&gpio2 27 GPIO_ACTIVE_HIGH>; //tc358775 reset
reset_always_high;
......

The AIO-3399J really has more advanced improvements to reach and monitor performance. Really this thread is great to understand the working principle better. The coreball model to operate really needs to be suitable to meet the stability.Author: elonlilx Time: 8/20/2025 17:55
