Chapter 4 About Debug

In the previous chapter, we introduced a variety of burning methods. ISP burning is mainly used to burn empty flash or uboot can’t start. In actual development, we usually update only one partition (uboot, kernel, rootfs…). , and the update frequency is very high. If you burn the whole system every time, it is very time-consuming (for example, only update the 2m kernel, but burn the entire 50m system image…). The following will introduce how to improve the development efficiency through the network.
