ROC-RK3328-CC supports booting from the following storage devices:
- SD card
You need to flash the firmware file to the SD card or eMMC, in order to make the board bootable.
SDCard Installer is the officially recommended SD card flashing tool, which is derived from Etcher / Rock64 Installer. It implements one-stop downloading and flashing of firmware file, which makes life easy.
There are two firmware file formats:
- Raw Firmware
- RK Firmware
Raw Firmware, when flashing, is copied to the storage device bit by bit. It is the raw image of the storage device. Raw Firmware is flashed to the SD card in common cases, but it can also be flashed to the eMMC. There are lots of flashing tools available:
- To flash to the SD card:
- To flash to the eMMC:
RK Firmware, is packed in Rockchip’s proprietary format, which is flashed to the eMMC via Rockchip’s upgrade_tool (Linux) or AndroidTool (Windows). It is Rockchip’s traditional packing format, commonly used in Rockchip Android firmware. RK Firmware of Android can also be flashed into SD card using SD Firmware Tool.
Partition Image, is the raw image of the partition. When you build the Android SDK, you’ll get a list of
system.img, etc, which is called Partition Image and will be flashed to the corresponding partition. For example,
kernel.img is to be flashed to
kernel partition in the eMMC or SD card.
