Tab5: Flash Firmware & Run Code

1. UiFlow2 Firmware Flashing

1. Refer to the UiFlow2 Web IDE Tutorial to understand the basic UiFlow2 workflow and complete the installation of the M5Burner firmware flashing tool.

2. Download the firmware for Tab5 in M5Burner, as shown below.

3. With the USB cable connected or the device powered by battery, press and hold the reset button (about 2 seconds) until the internal green LED indicator starts flashing quickly. Release the button, and the device will enter download mode and wait for firmware flashing.

4. In M5Burner, click the Burn button for the corresponding firmware, select the device port, and click Start.

5. Fill in the Wi-Fi configuration required by the device, including Wi-Fi SSID and Wi-Fi Password, as well as any other device configurations that need to be added or modified, then click Next to start flashing.

Configuration information description:

• COM: Select the serial port corresponding to the device
• BaudRate: Baud rate for serial communication
• Server: Server address the device connects to
• WIFI SSID/WIFI Password: Wi-Fi name and password for device connection
• SNTP Server:
  • SNTP0: Alibaba Cloud NTP server (China)
  • SNTP1: Japan NTP server pool
  • SNTP2: Global public NTP server pool
• Timezone: Time zone setting
• Boot Option: Sets the device startup mode after firmware flashing is complete
  • run main.py directly: After flashing is complete, directly runs the program in main.py without connecting to the network or displaying the UiFlow2 startup screen
  • show startup menu and network setup: The device connects to the network, and devices with a screen display the UiFlow2 startup screen
  • only net work setup: The device only performs network setup and does not display the UiFlow2 startup screen

6. When Burn successfully, click here to return is displayed, flashing is successful. Reset the device at this time.

7. After firmware flashing is complete, if you need to modify the device configuration, keep the USB connection, restart the device, click the Configure option, and modify the configuration according to the on-screen prompts.

2. Device Connection

The device supports connecting to UiFlow2 by Access Code (wireless network) or USB (wired computer connection), enabling program pushing and debugging. Refer to the following tutorials for details:

Access Code Wireless Connection

1. Before connecting, make sure the device is connected to the network. If the network is not connected, check whether the Wi-Fi name and password entered during firmware flashing are correct, modify them through the Configure option in M5Burner, and flash again.

2. View the currently generated valid Access Code on the device's UiFlow2 startup screen.

3. Visit uiflow2.m5stack.com to open the UiFlow2 Web IDE.

4. Click Select Your Controller (displayed on first entry) or the Controller button on the page to enter the Select Device page.

5. Click Connect Device, enter the access code and a custom device name, then click Confirm to connect Tab5 to UiFlow2.

USB Wired Connection

1. Visit uiflow2.m5stack.com to open the UiFlow2 Web IDE, and connect Tab5 to the computer with a USB Type-C cable.

2. Click Select Your Controller (displayed on first entry) or the Controller button on the page to enter the Select Device page.

3. Select the Tab5 device in the device list and click Confirm.

4. Click the WebTerminal button, select the serial port of Tab5 in the dialog box, and click Connect.

When the WebTerminal screen displays Connected to Serial Port!, the USB connection is successful.

3. Program Run and Download

After the device is connected to UiFlow2, you can drag Blockly blocks to edit programs.
