c. After the image writing is completed, click the "Exit" button to exit, and then you can pull out the TF card and insert it into the development board to start<br><br>

=== Supported Linux image types and kernel versions ===

3) There are a total of 17 GPIO ports in the 26pin interface, and the voltage of all GPIO ports is '''<span style="color:#FF0000">3.3v</span>'''<br><br>

=== How to use the use of wireless network card ===

1) At present, the USB wireless network card model that is adapted to the image is shown below：<br>

=== 26pin's PWM test ===

1) Android only opened '''PWM15''' by default. The corresponding pins are at the position of 26Pin.<br><br>

2) First click theWiringOP icon to open the Wiringop App<br><br>

3) Then click the '''PWM_TEST''' button to enter the PWM test interface at the main interface of WiringOP<br><br>

4) The corresponding address corresponding to the PWM15 is '''febf0030'''. The right side of PWMCHIP0 is exactly the '''febf0030.pwm'''. If the displayed base address is wrong, please click the drop -down option to select other PWMCHIP until the '''febf0030''' is displayed on the right.<br><br>

5) Then confirm the PWM cycle. The default configuration is '''50000ns''', and the PWM frequency is '''20KHz'''. You can modify it by yourself.Click on the button to export '''PWM15'''<br><br>

6) Then drag the drag below to change the PWM duty ratio, and then check the enable to output PWM<br><br>

=== 26pin's SPI test ===

1) From the schematic diagram of the 26pin interface, the SPI available for Orange Pi 5 is spi4<br><br>

2) Here is the w25q64 module to test the SPI interface, and first access the w25q64 device at the SPI4 interface.<br><br>

3) Then click the WiringOP icon to open the WiringOP APP<br><br>

4) The main interface of the WiringOP APP shows as shown in the figure below, click the SPI_TEST button to open the SPI test interface<br><br>

5) Then click the '''OPEN''' button to initialize SPI<br><br>

6) Then fill in bytes that need to be sent, such as reading the ID information of W25Q64, fill in the address 0x9F in data [0], and then click the '''TRANSFER''' button<br><br>

7) The last app will display the ID information read<br><br>

8) The MANUFACTURER ID of the w25q64 module is EFh, the Device ID is 4017h, and the value read above is corresponding (H represents hexadecimal)<br><br>
