There should be an eMMC on the CM4 Nano, the difference is just the eMMC size. And the eMMC is pre-installed 32-bit Raspberry Desktop OS with our BSP installed. Customers can just use it out of box and don't have to download a OS image and flash the eMMC. If customers want to reset to the factory settings, customers could get the latest images and reflash the eMMC.
Once you have downloaded the image file, please refer to section: eMMC Flashing to flash the eMMC.
