DownloadThis application facilitates STM32 microcontroller firmware updates via USB cable using the USB DFU protocol. Development leveraged STMicroelectronics documentation: AN2606 (STM32 microcontroller system memory boot mode) and AN3156 (USB DFU protocol in STM32 bootloader).
How to Use:
Prerequisites:
- Your mobile device must support USB On-The-Go (OTG).
Preparation:
- Connect your STM32 board to your mobile device using a USB OTG cable.
- Activate the STM32 bootloader mode (refer to AN2606 for specific instructions based on your CPU model; generally involves configuring BOOT0 and BOOT1 pins).
Programming:
- Select the firmware file (.hex, .srec, .dfu, or raw binary).
- Configure writing options: selective page erasing, readout protection disabling (if needed), and automatic CPU execution post-programming.
- Click "Load file to flash" and await completion.
Additional Features:
The application also provides:
- Flash erasing
- Flash blank check
- Firmware comparison against flash memory
These functions are accessible via the application menu.
Tested Microcontrollers:
STM32F072, STM32F205, STM32F302, STM32F401, STM32F746, STM32G474, STM32L432
Usage Restrictions:
The application allows up to 25 free firmware uploads. Beyond this limit, you can purchase:
- An additional 100 uploads.
- Unlimited application usage.
