| 摘 要： | 提出了一种扩展Uboot实现嵌入式设备操作系统维护与升级的方法。该方法将待升级的内核和文件系统映像放入SD卡中,当系统重启时,扩展后的Uboot会自动检测并读取SD卡中的映像文件,再烧写到嵌入式设备实现自动升级。该方法较传统的通过JTAG口、串口或者网口连接到主机,在主机上通过手动输入控制命令完成内核或者文件系统的升级方式更为便捷高效。

| Abstract: | An extension Uboot which achieves the method of maintaining and upgrading embedded device operating system is proposed. The method sends the kernel to be upgraded and file system image into the SD card, the extended Uboot can automatically detect and read the image file of SD card, and then program it to the embedded device for automatic update. Compared to through JTAG port, seri- al port or Ethernet port to connect the host and completes the upgrade of the kernel or file system on the host by manually entering con- trol commands, this method is more convenient and efficient. |
