Flashing
Kflash.py
Programs are loaded onto the MAix Bit using the kflash.py command line utility program. You must install this program before you will be able to flash the MAix Bit board with your TinyGo code.
The latest version of the kflash.py can be installed using pip3 install kflash.
- Plug your MAix Bit into your computer’s USB port.
- Build and flash your TinyGo program using
tinygo flash -target=maixbit [PATH TO YOUR PROGRAM]
Troubleshooting
You may get the following error when flashing the MAix Bit:
error: unable to locate a serial port
To resolve this, just specify the MAix Bit’s serial port when flashing using tinygo flash -target=maixbit -port=[MAIXBIT PORT] [PATH TO YOUR PROGRAM].
