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.
燒錄方法 (Flash eMMC Method)
Step1: 創造一張可開機的SD 卡 (Create a bootable SD card)
Step2: 將可開機的SD 卡插入底板SD卡卡槽(Plug the SD card into Carrier board 's SD card slot)
Step4: 確認開機選擇指撥開關
SD 卡開機模式:
Step3:打開電源 和 終端機 (Turn on the Power & Terminal)
Step4: 壓縮flash tools 檔案,並複製到U盤中(the flash tools file , then copy to USB Disk)
Step 5: Yocto 系統會自動掛載 U盤 在(run/media/sda1下)
並拷貝 5720A1AIM30LIVA0271_iMX8M_2G_flash_tool.tgz 到根目錄 (copy the file into Yocto system)
Commnd : cp -a 5720A1AIM30LIVA0271_iMX8M_2G_flash_tool.tgz /
在Yocto 系統中解壓縮(Unzip the file in Yocto system on ROM-5720)
Step 6. 燒錄eMMC 鏡像 (flash image into eMMC flash by flash tool file)
command : ./mksd-linux.sh /dev/mmcblk0
Step 7 . 結束燒錄後, 請改變撥碼開關至 1 on , 其他 off (eMMC開機模式) (Finish the flash process, please chanage the switch (SW1) to 1 on , others off )
移除SD卡, 拔除電源 ,改變撥碼開關 (unplug the SD card , turn off power , change the SW1 switch to eMMC mode (1 on , others off)
eMMC mode : 1 on , others off
Step 8. 重新上電開機 ( Turn on the power , then check the Debug message)
Debug 串口調試 (Debug port Setting)
以 Tera Term 为例介绍如何使用串口调试功能
