3.5eMMC Storage

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

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

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.
Verify Connection: Run lsusb on the host PC to confirm the device is detected.
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/
```
(One-Time Setup for New BSP): If this is the first time you are using this extracted BSP to flash or clone, you must first run the following command to prepare the environment. This step only needs to be done once per BSP extraction.
```
sudo ./flash.sh --no-flash [Device Target] [Storage Partition]
# e.g., sudo ./flash.sh --no-flash jetson-agx-orin-devkit mmcblk0p1
```
After the command completes, you may need to put the device back into recovery mode.
Execute Clone Command: Run the following command to create a backup image of the device's eMMC. This will generate a file named backup.img.
```
sudo ./flash.sh -r -k APP-G backup.img [Device Target] [Storage Partition]
# e.g., sudo ./flash.sh -r -k APP-G backup.img jetson-agx-xavier-devkit mmcblk0p1
```
This process will take several minutes to complete. Once finished, you will have a backup.img file in your BSP directory.

Rename the Image: Rename the newly created backup.img to system.img.
```
mv backup.img system.img
```
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.
Set Permissions: Grant the correct permissions to the new system image.
```
sudo chmod 755 bootloader/system.img
```

Prepare New Device: Take a new target device, put it into Recovery Mode, and connect it to the host PC.
Execute Flash Command: From the BSP root directory, execute the following command to flash the new device using the custom system.img:
```
sudo ./flash.sh -r [Device Target] [Storage Partition]
# e.g., sudo ./flash.sh -r jetson-agx-orin-devkit internal
```
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.
