03.05 eMMc

3.5eMMC Storage

This procedure applies to devices that boot and store the OS on internal eMMC storage.

The parameter for the eMMC storage partition depends on the Jetpack version used by the Advantech BSP:

Jetpack Version	Storage Partition Parameter
JP 6.0 or higher	internal
JP below 6.0	mmcblk0p1

3.5.1Step 1: Prepare the Master Device

Set up the master device (e.g., MIC-733, MIC-730AI) with all desired OS configurations, applications, and libraries.

3.5.2Step 2: Create the System Image (Clone)

1. Enter Recovery Mode: Shut down the master device, connect it to the host PC via the Micro-USB recovery port, and put it into Recovery Mode.

2. Verify Connection: Run lsusb on the host PC to confirm the device is detected.

3. Navigate to BSP Directory: In the terminal, change your directory to the location where you extracted the Advantech BSP for your device. For example:

   cd /home/user/MIC-733AO_Orin_5.1.2_V1.0.3_SDK/

4. (One-Time Setup for New BSP): If this is the first time you are using this specific extracted BSP, you must run an initialization command once. You may need to put the device back into Recovery Mode afterward.

   Device	One-Time Setup Command
   MIC-733	sudo ./flash.sh --no-flash jetson-agx-orin-devkit [Partition Parameter]
   MIC-730AI	sudo ./flash.sh --no-flash jetson-agx-xavier-devkit [Partition Parameter]

5. Execute Clone Command: Run the command corresponding to your device. This process creates the backup.img file.

   Device	Clone Command (Creates backup.img)
   MIC-733	sudo ./flash.sh -r -k APP-G backup.img jetson-agx-orin-devkit [Partition Parameter]
   MIC-730AI	sudo ./flash.sh -r -k APP-G backup.img jetson-agx-xavier-devkit [Partition Parameter]

3.5.3Step 3: Prepare the Image for Flashing

1. Rename the Image: Rename the newly created backup.img to system.img.

   mv backup.img system.img

2. Move the Image: Move the new system.img file into the bootloader/ subdirectory within your BSP folder.

   mv system.img bootloader/

   ℹ️ Note: If a system.img or system.img.raw file already exists in the bootloader/ directory, you should remove it before moving the new one.

3. Set Permissions: Grant the correct permissions to the new system image.

   sudo chmod 755 bootloader/system.img

3.5.4Step 4: Flash the Cloned Image (Restore)

1. Prepare New Device: Take a new target device, put it into Recovery Mode, and connect it to the host PC.

2. Execute Flash Command: From the BSP root directory, execute the following command to flash the new device using the custom system.img:

   Device	Flash Command (Restores system.img)
   MIC-733	sudo ./flash.sh -r jetson-agx-orin-devkit [Partition Parameter]
   MIC-730AI	sudo ./flash.sh -r jetson-agx-xavier-devkit [Partition Parameter]

   Once the flashing process is complete, the new device will boot up with an exact copy of your master system. You can repeat this step for all other devices you need to deploy.
