3. Program firmware

Step 1:

At first, you need to configure ISW1 switch on the NuMaker-PFM-M487 board. Set the four switches to ‘ON’ position. After the configuration is done, connect the NuMaker-PFM-M487 board and your computer using the USB Micro cable. After that, window manager will show a ‘NuMicro MCU’ virtual disk. Finally, you will use this virtual disk to burn firmware.

Step 2:

A simple firmware burning method is that you can drag and drop the binary image file to NuMicro MCU virtual disk or copy the binary file to NuMicro MCU disk to burn firmware.

4. Test

You can use Tera Term terminate emulator (or other software) to type commands of RTT. All parameters of serial communication are shown in below image. Here, you can find out the corresponding port number of Nuvoton Virtual Com Port in window device manager.
