Hello,

The procedure you have followed looks correct, I believe you’re trying to boot with dual LVDS-to-HDMI displays, please try by setting the bootargs as following:

U-Boot > setenv bootargs console=ttyLP0,115200 earlycon init=/init androidboot.console=ttyLP0 androidboot.hardware=nxp cma=1184M@0x960M-0xe00M androidboot.primary_display=imx-drm firmware_class.path=/vendor/firmware loop.max_part=7 androidboot.vendor.sysrq=1 transparent_hugepage=never androidboot.wificountrycode=CN androidboot.lcd_density=240

U-Boot > saveenv 

Also, a good way to check that you have set the bootargs correctly you may use the following command:

U-Boot > printenv bootargs

Best regards,
Aldo.
