This directory contains board definition files for a customised PYBD-SF2W board.
2+
It customises it as follows:
3+
- Default SYSCLK at 96MHz
4+
- Bluetooth support not included
5+
- Relocates ISR vector table to RAM
6+
- Prints a message before running boot.py
7+
8+
First, make sure all submodules are initialised in the micropython repository:
9+
10+
$ git -C ../../lib/micropython submodule update --init lib/lwip lib/mbedtls lib/stm32lib
11+
12+
Then build the firmware with:
13+
14+
$ make
15+
16+
To deploy the firmware to the board, make sure the board is in it's bootloader then run:
17+
18+
$ make deploy
