The displayed partition is as shown below (some computers may pop up more than twenty disk partitions, but they can only open the 128 MB one. partition), please note that this is normal, please do not think that the TF card is burned out. The reason for this is that there are more than twenty partitions in the Android system, but most of them cannot be recognized normally in the Windows system.

There is a 16MB SPI Flash on the development board, and its location is shown in the figure below:

A micro Linux system is programmed into SPI Flash by default. This system is mainly used to prove that the development board can start normally. After getting the development board, there is no need to burn the system into the TF card. You only need to connect the Type-C power supply to the development board to start the micro Linux system in the SPI Flash. The main functions of this system are:
