MiniSTM32F103ZE

Introduction

This page is about a development board named "CZ miniSTM32F103ZE-EK" found on Aliexpress.

Flashing the bootloader

To make it easy to upload software over USB, I recommend you install the stm32duino bootloader.

You need the stm32flash utility and a bootloader file for use with PE2.

Steps to flash the bootloader:

• wire a USB-serial converter to the board:

 serial GND -> board GND
 serial +5V -> board 5V
 serial RXD -> board A9
 serial TXD -> board A10

• put jumper BOOT0 in position 1 (to 3.3V)
• put jumper BOOT1 in position 0 (to GND)
• reset or power-cycle the board
• flash the bootloader using stm32flash:

 ./stm32flash -w ../../../../STM32duino-bootloader/binaries/generic_boot20_pe2.bin -v -g 0x0 /dev/ttyUSB0

• power down the board, put BOOT0 jumper back in position 0 (to GND)

If you now reset the board (e.g. press the reset button), you should be able to see the green LED flash.

You can now upload programs using the 'dfu' method.
