Currently, the Linux SDK maintained by Xunwei continues to follow the default partition structure of RK, while Xunwei has also maintained a set of custom partition structure SDK. Both partition structures have their own characteristics. The comparison between the RK default partition image and the custom partition image is as follows:
The traditional RK partition is suitable for systems with high boot speed requirements and fixed hardware configurations, such as industrial equipment and consumer electronics. In contrast, the custom partition is more suitable for multi-device environments and systems that require frequent updates, such as IoT and smart devices, reducing the complexity of image management and maintenance.
To enhance the diversity of the iTOP-RK3568/3588 system and provide customers with more system options, Xunwei has maintained a set of custom partition structure SDK and written a corresponding user manual 《【Beijing Xunwei】 iTOP-3568/3588 Custom Partition Image Compilation and Usage Manual》. The specific content of the manual is as follows:
