SD Card Boot / eMMC Flash

Option 1: Booting Directly from SD Card

1. Identify SD Card Device

   • Insert the SD card into your Ubuntu host.
   • Use sudo fdisk -l to find the device path (e.g., /dev/sdf).

2. Flash Image to SD Card

   • Run:

     sudo dd if=your_image.img of=/dev/sdX bs=1M conv=fsync
     Replace your_image.img and /dev/sdX with your actual image file and SD card device. Find in the Dropbox, it can be below:
     • 3720A1AIM34LIVC0047_iMX8MP_2G_2023-06-14.img
     • 3720A1AIM34LIVC0047_iMX8MP_6G_2023-06-14.img

3. Insert SD Card into Target Device

4. Set Boot Switch to SD Card Mode

   • Check the SW1 1 and 2 on

   

5. Connect Serial Terminal

   • Use a terminal tool (e.g., Tera Term).
   • Tera Term Settings:

   Setting	Value
   Baud Rate	115200
   Data	8
   Parity	none
   Stop	1 bit
   Flow Control	none

6. Power On and Boot

   • Observe boot messages from the SD card.

Option 2: Flashing Image to eMMC (via SD Card Boot)

Preparation:
First, complete the SD card boot process as described above.

1. Copy the eMMC Flash Tool to a USB Drive

   • Place the flash tool archive (e.g., xxx_flash_tool.tgz) on a USB stick.
   • Find in the Dropbox, it can be below:
     • 3720A1AIM34LIVC0047_iMX8MP_2G_flash_tool.tgz
     • 3720A1AIM34LIVC0047_iMX8MP_6G_flash_tool.tgz

2. Boot the Device from SD Card

   • Insert the SD card and boot into Linux.

3. Insert USB Drive into Target Device

4. Locate the USB Drive in Linux

   • For example: /run/media
   • Verify with ls command.
   • You should find sda1

5. Copy the Flash Tool to Root Directory

   sudo cp -a /run/media/sda1/xxx_flash_tool.tgz /

6. Extract the Flash Tool

   cd /
   tar -xvf xxx_flash_tool.tgz

7. Run the eMMC Flash Script

   cd /xxx_flash_tool/mk_inand/
   ./mksd-linux.sh /dev/mmcblk2
   • /dev/mmcblk2 is typically the eMMC device.
   • Confirm when prompted to erase eMMC.

8. After Flashing, Remove SD Card and Set Boot Switch to eMMC Mode

   • Check the SW1 2 on

   

9. Reboot and Boot from eMMC

   • Observe boot messages to confirm eMMC boot.
