Upgrade Steps

Step 1: Connect the Device and Check the Port

Connect your development board to the PC and confirm the serial port number of the current development board, as shown in the figure below:

The port number of my device is COM3 currently.

Step 2: Check the Device Version

1. Open the CMD and find the path of mcumgr.exe, such as C:\Users\glinet\Desktop\upgrade tool\windows.

2. Enter the command "cd your path of mcumgr.exe" to enter the mcumgr path

3. Enter the command to view the current firmware of the device.

   mcumgr.exe --conntype serial --connstring=your_board_port,baud=460800 image list

   

Step 3: Upload the Firmware

mcumgr.exe --conntype serial --connstring=your_board_port,baud=460800 image upload new_firmware_path

Step 4: Check the Uploaded Firmware Information

mcumgr.exe --conntype serial --connstring=your_board_port,baud=460800 image list

Step 5: Set the Firmware for next boot

mcumgr.exe --conntype serial --connstring=your_board_port,baud=460800 image test new_firmware_hash

Make sure the flags of the new firmware is pending.
