1.2 Write image into SD card
1. Format the SD card:
For windows
Before writing the system image, you need to format your SD card. You need to connect the SD card to the computer with a card reader. As shown below.
You need to use a tool to format the SD card: SD Card Formatter 5.0.1 Setup.exe
Note: This software in the【ownload】--【Tools】 folder.
For MAC
You can directly format the SD card using the tool that comes with the computer. After the format is completed, we can see the real memory of the SD card is displayed on the computer.
Finally, We need to Remove the SD card and card reader from the computer.
