SD card is very fragile performance is very unstable, accidentally broken off. SD card can greatly improve the cell phone or camera storage capacity, and greatly enhance the use. But if the SD card strike is broken, you will lose
card, CF card, etc.), to achieve flexible debugging and boot of the system kernel. The advantage of this mode of guidance is that you do not need to connect the host machine to the target board during debugging, which improves debugging.It is more convenient and flexible to use. When updating the kernel, it is more flexible. You only need to store the updated kernel to the specified directory. In addition,
