We have a custom board with i.MX8MQ and 4GB DDR4 but set as 3GB since GPU driver issue described in Vivante GPU driver and 4GB DDR .
I have ported BSP android_O8.1.0_1.3.0_8M on our custom board, after download image to eMMC, I can boot into Android desktop.
However, if I run any APP for example FILE APP, the HDMI display will become blank, even I reboot the board, the Android boot animation can be showed properly, but HDMI display will become blank again after BOOT_COMPLETE message showed on console.
I can get back HDMI display by clearing userdata and fbmisc partitions but same phenomenon will be appeared again when I run APP.
I attached the first boot logs, running APP logs, 2nd boot logs and a short video after clear partitions.
I used non DRM build, my boot image and system image can run on i.MX8MQ_EVK with its uboot and open APP properly.
Can anyone help?
