6.3 USB
6.3.1 Micro USB
The micro USB is mainly used for firmware upgrades and ADB function.
ADB is the command-line debugging tool. It can use for system logs, uploading and downloading the files, installing the applications, etc.
❶ connect the board and PC host with Micro USB cable.
❷ install ADB driver on Windows system.
❸ press Windows + R to open the Run program. Type cmd and press Enter
❹ execute commands to enable ADB and test.
Push the file com located in PC E:\EM3566\Tool\Test\ to the board for example:
1adb push E:\EM3566\Tool\Test\com /system
2adb shell
3chmod 777 /system/com //modify com properties
6.3.2 USB Host
The USB Host can be used to connect USB mouse, USB keyboard, U-Disk or other USB devices.
After inserting the USB flash drive, an icon will appear on the desktop. Click the icon to automatically mount the device.
