摘要
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.关键词
