ROM-2620

快速入门 (Quick Start)

系统下载 (OS Download)

• 'Linux系统 (Linux OS)'   

Yocto 4.0: IoTGateway/BSP/Linux/iMX8/OS Support List 4.0 release ROM-2620 - ESS-WIKI (advantech.com.tw)

Yocto 4.2: IoTGateway/BSP/Linux/iMX8/OS Support List 4.2 release ROM-2620 - ESS-WIKI (advantech.com.tw) 

Linux 燒錄方法 (Linux Flash eMMC Method)

使用Flash tool 燒錄鏡像到eMMC (Flash image into eMMC by Flash Tools) 

Step0: 檢查SD卡在Linux 環境的代號 (check SD card symbol in Linux system) 

Step1: 創造一張可開機的SD 卡 (Create a bootable SD card)

Command :

~$ sudo dd if=2620A1AIM34LIVC0054_iMX8ULP_1G_flash_tool/image/imx-image-full-imx8ulprom2620a1-20230627062759.rootfs.wic of=/dev/sde bs=1M conv=fsync status=progress

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)

Step3: 確認開機選擇指撥開關

Step4:打開電源 和 終端機 (Turn on the Power & Terminal)

Step5: 複製flash tool到U盤中, 解壓縮flash tools檔案,(copy to USB Disk, then unzip the flash tools file)(Test with 32G SD card)

    複製檔案到U盤中 (Copy the flash file to USB Disk), 解壓縮flash tool到home目錄(Unzip the file to home)

1. tar zxvf /run/media/New\ Volume-sda/2620A1AIM34LIVC0054_iMX8ULP_1G_flash_tool.tgz -C ~

5. 進入flsah tool下的mk_inand資歷夾, 執行指令./mksd-linux.sh /dev/mmcblk0燒錄image到eMMC(Connect USB Disk to ROM-2620 system, extract the flash tool and browser to mk_inand folder and execute flash shell script "./mksd-linux.sh /dev/mmcblk0"

解壓縮後如果沒有mksd-linux.sh檔案, 可以到以下連結下載並複製到mk_inand資料夾下(If there is no mksd-linux.sh file in mk_inand directory. Please download from the link below and place it in mk_inand directory:

mksd-linux.sh

6. 切換開機switch來設定成從eMMC開機(Change boot switch to boot from eMMC. Reboot system).

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

   Baud Rate波特率：115200

Tera Term Tool 

Check the Sriel port in Device Manager (查看PC端的串口号)：

if you can not identify the Serial device , please check your serial driver. 

Debug port connection (串口連接) 

Log into Terminal  Tool (进入串口调试终端)：
