Update to version 19.11.5 (20200120) kernel 5.5.0-rc6.
Important change. the way DTB is configured has changed. The universal multiload for the AML platform has changed. Now a single configuration method is used for all platforms, using the file (uEnv.txt). You need to edit this file to configure it. You need to uncomment the two lines that are responsible for your platform and specify the correct DTB for your model. If you use this image to run on the one platform, you can delete it from the settings file (uEnv.txt) strings from other platforms.
Pay attention. The installation algorithm in eMMC has changed. My recommend that you perform a clean installation in eMMC. Be sure to make a full backup of eMMC before installing it in eMMC. Important. On models S905\S905X and partially on S912, there may be problems with starting the desktop, management is possible only via SSH or UART.
For the aw H6 platform, all scripts are already in the image (which have the ending aw). You need to rename the files with the replacement (remove the .aw ending).
