¶ 2. Driver Installation Steps
¶ 2.1 Driver Installation
Select the "InstallUSBDrv.exe" file and double-click to install; a command window will pop up during the process and then close automatically.
¶ 2.2 Method to Enter Programming Mode
Press and hold the FEL button on the board, then press the RST button for 1 second and release, finally release the FEL button to enter programming mode.
Connection Method 1: Remove the board cover and connect directly on the machine. If the USB port is long, remove interfering cables; if the USB port is thick and interferes with the structure below, do not force it in to avoid damaging the female connector or poor contact. Please choose Method 2.
Connection Method 2: First power off, use the screwdriver from the tool kit to remove the screws fixing the board, then connect the USB port. After programming is complete, reinstall (recommended for beginners);
Alternatively, disconnect the FPC cable and remove the entire board, then reinstall after programming (for experienced users); When reinstalling the FPC cable, make sure to align it properly, otherwise it may result in poor contact and failure to power on normally.
Remember to power off before operation.
¶ 2.3 How to Determine if Driver Installation is Successful
Connect normally, open the computer's Device Manager, after the board enters programming mode, check if there is "USB Device(VID_1f3a_PID_efe8)" under "Universal Serial Bus controllers".
¶ 2.4 Driver Installation Successful
"USB Device(VID_1f3a_PID_efe8)" appears.
¶ 2.5 Driver Installation Unsuccessful
If "Other devices: Unknown device" appears, it means the driver was not successfully installed and the device cannot be recognized; you need to reinstall the driver.
¶ 3. Programming Steps
¶ 3.1 Connection

¶ 3.2 Open Programming Software
This software does not need installation, it can be used after extraction. Find "PhoenixSuit.exe" in the extracted folder and double-click to open.
¶ 3.3 Load Programming File
Click the browse button and select the programming file from your computer directory.
After selection, click open.
¶ 4. Programming File Precautions
Board type: For example: CR0CN240110C10; Select according to the machine model, one-to-one correspondence, otherwise it will not work.
Version: For example: V1.1.0.57; Select the version you need according to the official release notes for programming.
¶ 4.1 Programming Mode Selection
Selecting [YES] will delete all user data, similar to upgrading firmware after factory reset (recommended).
Selecting [NO] will only upgrade the firmware version and retain user data.
¶ 5. Programming Process Precautions
Do not power off, unplug the device, or press the reset button on the board during the programming process; normally, the entire programming process takes less than 30 seconds from start to finish; if it exceeds this time, an abnormality may have occurred, check if the connection is normal and if the board has entered programming mode.
