2. Recovery
按键Recovery按键,主要是方便系统进入 Recovery 模式,来对 EMMC 进行镜像烧录/下载。
使用方法是:打开瑞芯微开发工具,断电状态下先从 Type-C OTG 口插入数据线,先摁住Recovery按键不放,然后接入12V电源,当电脑瑞芯微开发工具界面提示识别到 Recovery 设备时,即可松开按键,进行下一步的镜像烧录。
可参照固件烧录章节。Key
The Recovery key is mainly used to enter Recovery mode for EMMC image flashing and downloading.
Operation steps: Open Rockchip Development Tool. With the power off, connect the data cable to the Type-C OTG port. Keep pressing the Recovery key, then connect the 12V power supply. Release the key once the tool detects the Recovery device, and proceed with image flashing.
Refer to the firmware flashing chapter for details.
3. Maskrom Key
The Maskrom key is used to enter MaskRom mode to flash and download images to EMMC. It is applicable for firmware corruption and system boot failure scenarios.
Operation steps: Open Rockchip Development Tool. With the power off, insert the data cable into the Type-C OTG port. Hold down the Maskrom key and connect the 12V power supply. Release the key when the tool recognizes the MaskRom device, then start image flashing.
