嵌入式系统中,Bootloader的意义与作用与PC上的BIOS有点类似,它对开发板上的主要部件如CPU、SDRAM、FLASH、串口等进行了初始化,可以使用Bootloader下载文件到开发板,可以浏览目录,可以烧录flash,可以启动系统等,实际上,一个功能比较强大的Bootloader已经相当于一个微型的操作系统了。
That connection may be a common protocol such as I2C, USB, or UART, or it may be a proprietary protocol. Figure 1 shows that the product's embedded firmware must be able to use the communication port for two purposes: normal operation and updating flash. The portion of the embedded ...
