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=2820A1AIM36LIVD0042_iMX93_2G_2024-05-26.img of=/dev/sdh bs=1M conv=fsync
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 |
System ID : root
Password : 12345678
Step4:打開電源 和 終端機 (Turn on the Power & Terminal)
Step 5: 按下Power 開關 (Turn on Power , open terminal , then press the Power Button )
SW1003 : PWR_Button , SW1002: Reset_Button
Step6: 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)
- Format your USB Disk to ext2 format
Command : sudo mkfs.ext2 -F /dev/sdX
2. Unzip the flash file in your linux system
3. Copy the flash file into USB DISK
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:
mksd-linux.sh
| ROM-2820 | Device node |
| SD card | /dev/mmcblk1 |
| eMMC | /dev/mmcblk0 |
Step 7 . 移除SD card , 切換開機switch來設定成從eMMC開機(Romve SD card and Change boot switch to boot from eMMC. Reboot system).
| SD boot: | 1 on , 2on |
| EMMC boot: | 1 off , 2 on |

Camera使用方法(Camera Testing Method)
MIPI-CSI0 (Tested with OV5640 + mini-SAS to MIPI-CSI Cable): OV5640 CSI (CN701): Connect OV5640 camera to EG-55 CAM3
Step 1: Take pictures
Step 2: View on panel
PWM測試方法(PWM Testing Method)
TBD
CAN Bus
Step 1: Connect can1 and can2
Step 2 Test command
# ip link set can0 up type can bitrate 125000
# ip link set can1 up type can bitrate 125000
# candump can1 &
# cansend can0 12345678#123412341234
The following shows the result
can1 12345678 [6] 12 34 12 34 12 34
LPUART
Step 1: Change ROM-ED91 SW1203 to '01'.
Step 2: Connect COM-B and COM-E to PC.
Step 3: Set RTS/CTS flow control for COM-B in Putty.exe
Step 4: After select the test mode ‘U’ to verify LPUART2, you will see below screen.
Step 5: If tester can input any characters/strings and show that at COM-B means test successful.
