Radxa Zero can boot from either eMMC or microSD Card. However, for beginner it’s best to stick with your board’s default storage, i.e. use eMMC when it is present, and microSD when eMMC is not available. This avoids the need to update U-Boot configuration to boot your chosen device, which can be challenging for the beginner.
