As a mainstream embedded storage solution, the combination of eMMC 5.1 and Rockchip RK3568 chip is a classic combination for embedded development in industrial, consumer, IoT and other fields. RK3568, as a quad core A55 processor designed for mid to high end embedded scenarios, natively supports the eMMC 5.1 protocol. The adaptation of the two can fully leverage hardware performance and meet the storage needs of various embedded scenarios.
Core Application Scenarios of eMMC 5.1 in RK3568 Development Board
The positioning of RK3568 covers industrial control, intelligent terminal, Internet of Things gateway, edge computing and other fields. eMMC 5.1, as the on-board primary storage, is the key to the landing of these scenarios:
System Startup and Root File System Storage
Startup Medium: RK3568 supports priority startup from eMMC 5.1 (default startup order: eMMC > SD card > SPI NAND). The high stability and read-write speed of eMMC 5.1 ensure fast system startup (Linux/Android system startup time can be controlled within 3-8 seconds, far superior to SD card).
Root File System Hosting: The root file system (rootfs), kernel image (zImage/Image), and device tree (dtb) of embedded Linux (such as Buildroot, Yocto) or Android systems are all stored in eMMC. High speed read and write in HS400 mode can reduce system lag and improve application response speed.
Example: RK3568 gateway device, which stores Ubuntu Core system through eMMC 5.1, can quickly load drivers and network protocol stacks to meet the real-time data forwarding requirements of the gateway.
