Title: LVDS for RK3399C AIO for Android10 [Print This Page] Author: jdurkop Time: 10/5/2021 14:31 Title: LVDS for RK3399C AIO for Android10 I was looking into using the LVDS HSX101H40C display with the RK3399C-AIO board, but have not been able to get it working yet. For the builds I have been attempting to use the rk3399-firefly-aio-lvds-HSX10140C project, but when looking at the files that support it, it appears that one is really for the RK3399J. When I received this device the board and panel were working properly with the stock android 7.1 image loaded on it, but when I go to use the Android10 build built with that project, the display is not working. Is there a different project I should be using or a specific set of changes to .dst files that can get this display working on the latest android build? The error message I am seeing during boot up is this.
