Hi,

 

I downloaded linux demo image then wrote it to my sdcard.

demo image: https://www.nxp.com/webapp/Download?colCode=L4.9.51_IMX8MQ_Beta
vcp-driver: https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers

 

$sudo dd if=fsl-image-qt5-validation-imx-xwayland-imx8mqevk.sdcard of=/dev/sdb bs=1M
$sudo dd if=imx-boot-imx8mqevk-sd.bin-flasg-hmdi-spl-uboot of=/dev/sdb bs=1k seek=33

 

It looked EVK boot up successfully but HDMI port output no signal at all.

How do I configure the display port for HDMI?

 

Once I tried to fix setenv of u-boot as following but nothing changed.

u-boot> setenv mmcroot /dev/mmcblk1p2 rootwait rw video=HDMI-A-1:1920x1080-32@60
u-boot> saveenv
u-boot> boot

 

Can anyone help me?
