My screen is not display when I connect it with RZ/V2l by micro hdmi cable

Question

I built an OS for RZ/V2L using yocto with core-image-weston and booted from SD successfully. Console shows up and can login as root. However when I connect it to a monitor via micro hdmi nothing is displayed. Has anyone had similar problems that can help me?

Hello Huuuu 
 Please refer to my build file. It appears that your SD card files may be corrupted, which is causing this error. Kindly check the manual for instructions on flashing the SD card. Additionally, ensure that you are uploading the correct DDR files as per the board specifications.

Hi, Can you see any messages on the console when you connect the HDMI on board? Kind Rergards.

Hello Huuuu

I attempted a clean build following the instructions in this manual, and it worked perfectly. Please take a look at this and include the graphics layer while building the image.
