Otherwise, it may cause XIAO to short circuit or not work properly, and the consequences caused by this will be borne by the user.

+## BootLoader Mode
+
+Sometimes, using the wrong program can cause the XIAO to lose its port or not function correctly. Common issues include:
+
+- The XIAO is connected to the computer, but no port number is found.
+- The XIAO is connected, and a port number appears, but the program upload fails.
+
+When you encounter the above two situations, you can try to put XIAO into BootLoader mode, which can solve most of the problems of unrecognized devices and failed  uploads. The specific method is:
+
+- **Step 1.** Press and hold the `BOOT` button on the XIAO RA4M1 without releasing it.
+- **Step 2.** Keep the `BOOT` button pressed and then connect to the computer via the data cable. Release the BOOT button after connecting to the computer.
+- **Step 3.** Upload the **Blink** program to check the operation of the XIAO RA4M1.
+
+## Reset
+
+When the program runs abnormally, you can press `Reset` once during power-up to let XIAO re-execute the uploaded program.
+When you press and hold the `BOOT` key while powering up and then press the `Reset` key once, you can also enter BootLoader mode.
+
+## Run your first Blink program
+
+By now, I believe you have a good understanding of the features and hardware of the XIAO RA4M1. Next, let's take the simplest Blink program as an example and perform the first blink for your XIAO RA4M1!
+
+- **Step 1.** Launch the Arduino application.
+- **Step 2.** Navigate to **File > Examples > 01.Basics > Blink**, open the program.
+<div style={{textAlign:'center'}}><img src="https://files.seeedstudio.com/wiki/XIAO-R4AM1/img/blink_code.png" style={{width:700, height:'auto'}}/></div>
+
+- **Step 3.** Select the board model to **XIAO RA4M1**, and select the correct port number to upload the program.
+<div style={{textAlign:'center'}}><img src="https://files.seeedstudio.com/wiki/XIAO-R4AM1/img/choose_board.png" style={{width:700, height:'auto'}}/></div>
+
+Once the program is successfully uploaded, you will see the following output message and you can observe that the orange LED on the right side of the XIAO RA4M1 is blinking.

+
+Congratulations, you've learned how to write and upload programs for the XIAO RA4M1!
+:::note
+The LED will only turn off when the user LED pin on the XIAO RA4M1 is set to a high level, and it will only turn on when the pin is set to a low level.
