Install System Using Card Reader
Only the ROCK 4D without SPI Flash version supports eMMC startup, and the version with on-chip SPI Flash does not support eMMC startup.
This guide explains how to use the Radxa eMMC/UFS module reader with an eMMC module to install the system onto the eMMC module.
Installing the system will format the eMMC module. Please back up any important data in advance!
