基于CK-Core的安全芯片Bootloader开发与应用

随着嵌入式技术的快速发展，多接口和多功能的Bootloader得到越来越多的应用，但其设计开发过程却非常复杂。为了实现定制安全芯片的软硬件初始化，并成功下载其片内操作系统（COS），设计并实现了一种支持多接口和多功能的Bootloader。该Bootloader根据安全芯片及其CK-Core CPU的结构特点开发，程序结构简洁高效，对Bootloader的设计和开发提供了有力参考。

Development and application of security chip bootloader based on CK-Core

With the rapid development of the embedded system technique,Bootloader with multi-interface and multi-func-tion is widely used. However,the design and realization of the Bootloader is considerable complex. In order to realize the soft-ware and hardware initialization of the customized security chip,and to download Chip Operation System（COS）for the security chip successfully,a Bootloader with multiple interfaces and functions was designed and realized. The Bootloader was developed according to the architecture of the security chip and its CK-Core CPU. It has an efficient code structure,which contributes valu-able references to the design and development of other Bootloader.
