Update firmware for Motion core board
This section introduces a simple method for updating firmware on a Motion core board:
Use tyutool to upload the firmware to the Motion core board.
Download tyutool
Please download and install the version of tyutool that corresponds to your current operating system.
Upload the firmware
NOTE:
When connecting the mainboard to the computer via a USB cable, on macOS, two serial device names should appear (one starting with "cu.usbmodem" or "tty.usbmodem", and the other starting with "cu.wchusbserial" or "tty.wchusbserial"); you must use the device with the name starting with "tty.wchusbserial" or "cu.wchusbserial".
If your computer does not detect the corresponding serial port device name after you plug in the USB cable, please refer to the Download and install the USB driver section.
You can connect the Motion core board to your computer using a USB Type-C data cable and upload the Tuya-based upgrade firmware as follows:
Select the serial port device name connected to the AI core board. Select the serial communication baud rate: 921600 Select the chip platform: ESP32-S3
Select the option: Flash
Click the Browse... button to open the file browser and select the .bin file containing "merged", as shown in the image above.
Click the Start flash button.
Complete initialization configuration
After uploading new firmware, as shown in the image below, open the serial monitor:
Press the Reset button on the side of the robot body:
Restart the program. If you drag the scroll bar on the right to the bottom and see the following print information: Reset the joint’s calibration offsets? (Y/n)
Input "n", and click the Send button to skip, then observe the output serial port print information.
If you do not see the prompt "Reset the joint’s calibration offsets? (Y/n)", You can close the Serial Monitor directly.
The Serial Monitor will display: Calibrate the Inertial Measurement Unit (IMU)? (Y/n): Input "n", click the Send button to skip, and then observe the output serial port print information.
The Serial Monitor will display: Run factory quality assurance program? (Y/n): You can input "n" and click the Send button to skip, or wait for the 5-second countdown to skip automatically. Then, you'll see "Ready", indicating the program has automatically entered normal startup mode.
At this point, you can click the Close button in the upper right corner to close the Serial Monitor.
This step is not required for subsequent robot restarts.
