At one time I had a COM4 port that would allow communication with the Thing Plus Matter board. This worked with Simplicity Studio and Arduino IDE.
Now that COM port is not present and I cannot get either development environment to communicate with this board.
What driver do I need to communicate with the board. Following the Getting Started guide at: https://github.com/SiliconLabs/arduino? … me-ov-file, I have installed Segger J-link V7.96n but that hasn’t had any effect.
I found that by removing Segger J-Link “n” and using “g” I was able to at least discover the board on a COM port and can see serial communication. But am unable to reprogram or burn the boot loader to it.
Using Arduino 2.3.2, Sketch reflash attempts:
Sketch uses 869956 bytes (55%) of program storage space. Maximum is 1572864 bytes.
Global variables use 178676 bytes (68%) of dynamic memory, leaving 83468 bytes for local variables. Maximum is 262144 bytes.
