摘要
为了跟上旋转导向工具产业化的进度,设计了一种基于系统芯片的引导程序(Bootloader)。通过指定的烧录软件进行Bootloader编程,用户程序可在Uload模式下通过Bootloader实现自动更新下载,配合便携式程序下载移动终端,使用户程序的更新脱离了上层系统软件的束缚。重点介绍Bootloader设计和在移动终端设备上实现程序更新的实验。结果表明,设计的Bootloader配合移动终端设备,实现了旋转导向工具系统程序的自动更新下载,大大提高了这一过程的可操作性和灵活性,满足旋转导向工具高效可靠的产业化要求。
In order to keep pace with the industrialization of rotary steerable tool,a Bootloader based on system-on-chip is designed.Through specific burn software,Bootloader code was programmed.The user code can automatically update using Uload mode.Working with portable mobile terminal,the update of the user code is out of bounds to the upper system software.This paper focuses on the design of Bootloader and the experiment of updating program on mobile terminal.The results show that the designed Bootloader,cooperating with the portable mobile terminal,realizes the updating and downloading program of rotary steerable tool.This design greatly improves operability and flexibility in program updates,and meets the requirements of efficient and reliable industrialization of rotary steerable tool.
