Debug port 連接與設定(Debug Port Connection and Setting)

1. RSB-3810 debug port is shared with COM1. Please connect the debug console cable 1700034345-01 & 1700019474. Then connect the USB-to-RS232 Cable to your PC terminal. Connect the cable to COM1 pin header to the nearby the HDMI connector.

2. RSB-3810 can communicate with a host server using serial cables. Common serial communication programs such as HyperTerminal, Tera Term or PuTTY can be used in such applications. The example demonstrated below describes the serial terminal setup using Tera Term on a Windows host: Open Tera Term on your Windows PC, set the Baud rate to 921600.

GPIO Loopback Test (Using GPIO2 and GPIO4 as examples):

Step 1: Connect GPIO2 and GPIO4
Step 2: Export GPIO interface

echo 315 > /sys/class/gpio/export
# echo 316 > /sys/class/gpio/export

Step 3: Set GPIO direction

echo out > /sys/class/gpio/gpio1/direction
# echo in > /sys/class/gpio/gpio2/direction

Step 4: Read value and set output value than check

cat /sys/class/gpio/gpio2/value 0
# echo 1 > /sys/class/gpio/gpio1/value
# cat /sys/class/gpio/gpio2/value
1

Watchdog使用方法(Watchdog Testing Method):

Internal Watchdog:

System will reboot after 30 sec

# echo 1 | sudo tee /dev/watchdog # or /dev/watchdog0

External Watchdog:

System will reboot after 60 sec

# echo 1 | sudo tee /dev/watchdog1
