Serial Terminal
4.2 Display
Display Ports
Idea3588S supports Triple-display: MIPI LCD, HDMI and Type-C(DP Alt Mode).
Warning
MIPI LCD hot swapping is not allowed.
Debian Triple-display
4.3 USB Type-C
Docking station
Features Supported by the Type-C Interface:
Reversible Design: Allows insertion in either orientation for user convenience.
Data Transmission Roles: Supports flexible designation of host and device roles.
Multiple Protocol Support: Compatible with USB 3.0 and DisplayPort, enabling high-speed data transmission.
4.3.1 ADB
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 Type-C cable.
❷ Install ADB driver on Windows system.
❸ Press Windows + R to open the Run program. Type cmd and press Enter
❹ Execute command to enable ADB.
1adb shell
enable ADB
4.3.2 Type-C to USB3.0
Idea3588S supports Type-C to USB3.0. The device can use directly without install any driver.
After inserting the USB3.0 flash drive, an icon will appear on the desktop. Click the icon to automatically mount the device.
Type-C to USB3.0
4.3.3 DP Alt Mode
DisplayPort Alternate Mode (DP Alt Mode) is a technology that facilitates the transmission of DisplayPort video signals through a USB Type-C interface. It enables devices to output video and audio via a USB-C connection without requiring a dedicated DisplayPort connector. This allows users to connect a display using a single USB-C port while transmitting video, audio, and additional data.
Boardcon has conducted the testing at Type-C to HDMI/DP (3840x2160 @ 60Hz).
Type-C to HDMI
4.4 Ethernet
Connect the Board and router with an Ethernet cable.
