- No flow control
- Download the program to the target board.
- Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
Note: To debug in qspiflash, following steps are needed:
- Select the flash target and compile.
- Set the SW8: 1 off 2 off 3 on 4 off, then power on the board and connect USB cable to J23.
- Start debugging in IDE.
