To flash the pre-built firmware to your K210 board, run (in this directory):

./ktool.py -p /dev/ttyUSB0 -b 2000000 -t MicroPython.bin

Change /dev/ttyUSB0 to the port used to connect to the board if needed.
You can replace MicroPython.bin with sqlite/MicroPython.bin, twotasks/MicroPython.bin or ota/MicroPython.binto flash another firmware.

MicroPython.kfpkg is also provided which contains prebuilt LittleFS internal file system.
To flash it, just replace MicroPython.bin with MicroPython.kfpkg.

Flashing OTA firmware

OTA firmware is suposed to run with KBoot bootloader.
Kboot bootloader is included in ota/MicroPython.kfpkg, when flashing for the first time, always use MicroPython.kfpkg, not a MicroPython.bin!

After the Kboot bootloader is flashed, you can later flash only the MicroPython binary using the command:

./ktool.py -p /dev/ttyUSB0 -a 65536 -b 2000000 -t MicroPython.bin
