Micropython Firmware / Bootloader

For STM32F405RGT

• Upload firmware hex by ST-link, no need reset pin

• Flash Firmware - TPYBoardV102.hex

• Reboot board and connect by USB, it will format itself, two LEDs ON, this takes 3-5 seconds

• after this, U-disk will show up and sequential LED blink.

• Now can upload new sketch into it.

hardware flash size

Since the memory of STM32F401 is small, you need to install flash to simulate a USB flash drive. Recommended flash: W25Q32JVSSIQ 32MBit

The memory of STM32F411 is twice as large, so you don’t need an external flash to simulate a USB flash drive

Open the USB flash drive, edit the main.py file, click Save, reset the MCU and you can execute the program.
