快速入門 (Quick Start)

系统下载 (OS Download)

  • 'Linux系统 (Linux OS)'   

Yocto 4.2: IoTGateway/BSP/Linux/iMX8/OS Support List 4.2 release ROM-2820 - 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) 

RTENOTITLE

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

Command :

sudo dd if=2820A1AIM36LIVD0042_iMX93_2G_2024-05-26.img of=/dev/sdh bs=1M conv=fsync
RTENOTITLE

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

SD  boot: 1 on , 2on
EMMC boot: 1 off , 2 on 

AT/ATX mode Jumper 

AT mode 2&3
ATX mode 1&2

RTENOTITLE

System ID : root

Password : 12345678

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

RTENOTITLE

RTENOTITLE

Step 5:  按下Power 開關 (Turn on Power , open terminal , then press the Power Button )

            Command :  sudo mkfs.ext2 -F /dev/sdX 

       2. Unzip the flash file in your linux system 

           RTENOTITLE

     3. Copy the flash file into USB DISK 

          RTENOTITLE

     4. 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-2820 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:

下載 mksd-linux.sh

ROM-2820 Device node
SD card /dev/mmcblk1

i2cset -y -f 4 0x21 0x07 0xfc

Step 3: Run below command: 

# sudo chmod 775 rs485.sh
# ./rs485.sh
# stty -F /dev/ttyLP4 -echo -onlcr 115200
# cat /dev/ttyLP4 &
# echo "Serial Port Test" > /dev/ttyLP4

Step 4: You need to open two terminals: one to connect to the debug port of the ROM2820, and the other to connect to the Adam-4520.

Step 5:You can send data from the ROM2820's debug port to the Adam-4520, and you can also input text from the Adam-4520's terminal using the keyboard so that the ROM2820's debug port can receive it.

USB測試方法(USB Testing Method)

USB disk test (USB 2.0)


Step 1:Issue the following command (lsusb -t) after inserting a USB disk into the USB 2.0 port to check if the USB device is listed.

Step 2: Test (eg. if usb disk is /dev/sda) 

# dd if=/dev/urandom of=data bs=1 count=1024
# dd if=/dev/sda of=backup bs=1 count=1024 skip=4096 # dd if=data of=/dev/sda bs=1 seek=4096
# dd if=/dev/sda of=data1 bs=1 count=1024 skip=4096 # diff data data1
# dd if=backup of=/dev/sda bs=1 seek=4096

 

RTC測試方法(RTC Testing Method)

Step 1: Set system time to current, then write to RTC

root@imx93rom2820a1:~# date 010100002025 && hwclock -w && date

Step 2: Set one incorrect time, then read time from RTC to verify

root@imx93rom2820a1:~# hwclock -r && date

Step 3:  Restore the RTC time to system time 

 root@imx93rom2820a1:~# date

eMMC/SD測使方法(eMMC/SD Testing Method)

Device Routes

# dd if=/dev/mmcblk0 of=backup bs=1 count=1024 skip=4096
# dd if=data of=/dev/mmcblk0 bs=1 seek=4096
# dd if=/dev/mmcblk0 of=data1 bs=1 count=1024 skip=4096
# diff data data1
# dd if=backup of=/dev/mmcblk0 bs=1 seek=4096
