Debug Port連接 (Ddbug Port Connection)

1. Connect debug cable to EPC-R3430 debug port

2. Connect the other side of debug cable to USB-to-RS232 cable then connect to your PC

Debug Port設定 (Debug Port Settings)

EPC-R3430 can communicate with a host server by 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 EPC-R3430 with your PC by using a serial cable

2. Open HyperTerminal on your Windows PC and select the settings as shown below

3. After the boot loader is programmed on Micro SD card, insert power adapter connector to DC jack on EPC-R3430 to power up the board. The boot loader prompt is displayed on the terminal screen. HyperTerminal Settings for Terminal Setup

Linux 燒錄方法 (Linux Flash eMMC Method)

1. 確認SD 在Ubuntu 電腦中的代號(Check SD symbol in Ubuntu system)

2. 先將鏡像燒錄到SD Card 中( Create a bootable SD card )

3. 設定終端機(Set Debug Terminal)

通用方法(General Method)

查看CPU温度(Check CPU Temperature)

root@imx8qxprom5620a1:/# cat /sys/devices/virtual/thermal/thermal_zone0/temp 44600

# 或者直接以度爲單位顯示 echo $[$(cat /sys/class/thermal/thermal_zone0/temp)/1000]° >>> 45°

查看CPU频率(Check CPU Frequency)

cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq 
>> 900000
cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq    
>> 1200000
