# Firmware Flashing
The Type-C port on the side of the module supports both firmware flashing and power supply.

When the vision module is connected to a computer via a Type-C cable, the computer will recognize two serial ports: 

+ The larger-numbered COM port → corresponds to the onboard ESP32.
+ The smaller-numbered COM port → corresponds to the K210 chip.

**Note: The actual COM port numbers may vary depending on the operating system. It is recommended to check them via the Device Manager or a serial terminal tool.**

**Flash Files:**  
Download the required firmware files from the [official website](https://www.icrobot.com/www/cn/index.html#/file/index?type2=ICreate%20AI%20Vision).

## Flashing the K210
1. Open the flashing tool: Launch kflash_gui and select Erase.

## ESP32-S3 Firmware Flashing
**The onboard chip is ESP32-S3FN8. You can either program and flash it using Arduino IDE, or use the official Espressif Flash Download Tool.**

1. Configure the program:

Open the flash_download_tool_3.9.3.exe application, select ChipType = ESP32-S3, and click OK.

3. Upload the firmware:

Click “...”, and in the dialog box select the file k210_esp32s3_v1.0.0.bin. Set the address to 0x00, and check the box in front of the firmware file.

4. Flash the firmware:

Click “START” and wait until the progress bar is completed. A “FINISH” message will indicate that the flashing process has been successfully completed.

5. Verification:

Open a serial debugging tool and select the larger COM port. If the flashing is successful, the module will return output similar to the example shown in the figure.
