System Image
You need to prepare in advance the image file built by the Yocto project: core-image-minimal-rockchip-rk3588s-radxa-cm5-io.rootfs.wic.
For the Yocto project build steps, refer to the Build System document.
Install System to Onboard eMMC
This section describes how to use the RKDevTool tool to flash the system image to the onboard eMMC.
Note: Make sure the board has entered Maskrom mode and is correctly recognized by the system.
To use the RKDevTool tool, you must ensure the board is already in Maskrom mode (during power-on, if the Maskrom button is detected as pressed, the board will automatically enter Maskrom mode).
On Windows, to use RKDevTool you need to download and install the Rockchip_DriverAssistant driver.
