Also I tried to write Reclabox Pi zero image to emmc but it is same as the Pi3 image, hdmi is no view

Hello , I bought a Compute Module 3 and mother board , and I hope to install recalbox on it.

I tried to write Recalbox Pi3 image to emmc, but hdmi is no view when cm3 boot.
Then I copy 'bcm2710-rpi-cm3.dtb' file to system partition, and boot again, but hdmi is no view yet.

I have no idea how to sovle this.
Thank you for help!
