UART

User Debian/Linux UART/serial port access is through the tty-devices. The ttydevices have different names depending on UART drivers for different boards.

Device Node COM Port Name
/dev/ttyFIQ0 Debug
/dev/ttyS0 COM1（COM1_2 connnector  RS232 2-wire）
/dev/ttyS6 M.2_E1（UART）

DEBUG Port Connection

1.Connect the debug port cable on AOM-DB3500.

2.Connect it to your PC with a USB to COM Cable.

DEBUG Pin Connector
Pin Signal
1 NC
2 RX_DEBUG
3 TX_DEBUG
4 NC
5 GND
6 NC
7 RTS#
8 CTS#
9 NC

 

Debug Port Settings

AOM-3821 can communicate with a host server using serial cables. Common serial communication programs such as HyperTerminal, Tera Term, or PuTTY can be used in this case. The example below describes the serial terminal setup using HyperTerminal on a Windows host:
1. Connect AOM-3821 with your PC using a serial cable.
2. Open HyperTerminal on your Windows PC, and select the settings demonstrated in the photo below.
3. Insert a power adapter into the DC jack and power up the board. The Debug  console log will be displayed on the terminal screen.
