Boot modes

9.1

Bootloader mode

In order to update the firmware of the FiPy device, it

needs to be placed into bootloader mode. In order to

do this, P2 needs to be connected to ground when the

device reboots. Once in bootloader mode you can use

the Pycom firmware update tool to update to the latest

official firmware. If you are developing your own firmware

based on our open–source firmware, a flashing script is

provided with the source code.

9.2

Safe boot

The micropython firmware features a safe boot feature

that skips the boot.py and main.py scripts and goes

straight to the REPL. This is useful if the device is

programmed with code that causes the device to crash or

become inaccessible. To access this mode, you need to

connect P12 to 3.3V and reset the device. Upon entering

safe boot mode, the on–board LED will begin to blink

orange. Depending on the duration the pin is held at 3.3V,

a different firmware will be run.

Current consumption by power modes/features measured at 5V

10.0 Power

The FiPy features an on–board voltage regulator that

takes 3.5V – 5.5V from the VIN pin and regulates it to

3.3V. It is important to only use the 3.3V as an output

and not try to feed 3.3V into this pin as this could

damage the regulator.
