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=5521A1AIM38LIVG0009_iMX95_8G_2025-03-06.img of=/dev/sdf 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)

Step4: 確認開機選擇指撥開關

SD 卡開機模式: (2, 3:on, others off)

eMMC 開機模式: (1: on, others off)

Step3:打開電源和終端機 (Turn on the Power & Terminal)

Step4: 下載flash tools image檔案,並複製到U盤中(Download and copy the flash tool image file, then copy to USB Disk), USB Disk use the exFAT file system for an example.

Step5: 將U盤連接到AOM-5521系統, 解壓縮image檔(Connect USB Disk to the AOM-5521 system, then unzip the flash tool image file)

解壓縮(Unzip/tar the file), 先設定系統時間(setup system time first), tar解壓縮加入--no-same-owner參數(tar + --no-sam-owner)

# date -s "2025-05-21 16:21:00"

# tar zxf 5521A1AIM38LIVG0009_iMX95_8G_flash_tool.tgz --no-same-owner

5. 將U盤連接到AOM-5521系統, 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 AOM-5521 system, browser to mk_inand folder and execute flash shell script "./mksd-linux.sh /dev/mmcblk0"

如果mk_inand資料夾下沒有mksd-linux.sh檔案, 請到以下連結下載並複製到mk_inand下(Please download the mksd-linux.sh file from the link below if there is no script file in mk_inand deiectory)

Download mksd-linux.sh in https://github.com/ADVANTECH-Corp/RISC_tools_scripts/blob/mickledore/imx8/mksd-linux.sh

AOM-5521
SD card	/dev/mmcblk1
eMMC	/dev/mmcblk0

# ./mksd-linux.sh /dev/mmcblk0

6. 切換開機switch 1:on 2,3,4,5,6:off來設定成從eMMC開機(Change boot switch to "1:on 2,3,4,5,6:off" to boot from eMMC. Reboot system).

遠程訪問及文件傳輸(Remote Access and File Transimmion)

查看主板IP位址 ( Chech IP Address )：

        Command: ifconfig

Windows下SSH访问及文件传输

SSH Remote Log into Device

SSH远程登录,以putty选择putty.exe(或者使用Xshell、SecureCRT等类似软件)
需要设置远程设备的IP、通讯端口(默认22)、通讯方式，登录后验证用户名密码

通用方法(General Method)

查看CPU温度(Check CPU Temperature)

    # cat /sys/devices/virtual/thermal/thermal_zone*/temp

    # 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/cpu*/cpufreq/cpuinfo_cur_freq 
           >> 500000
           # cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_max_freq   
           >> 1800000
