Nucleo f401re in dfu mode5/25/2023 ![]() So my real question would be how to get MicroPython onto the STM32F4, the important question would probably be how to get the board recognized as DFU device. Sadly that doesn't really help me in respect to MicroPython. Once the chip is started in DFU mode, BOOT0 no longer needs to be held. The only success at all that I had so far was getting STLink Utility to recognize the board and being able to upload. Note that for most ST development boards such as the Nucleo and Discovery series. installing the Virtual COM Port driver from the ST webpage.downloading and installing USB drivers from the official STMicroelectronics webpage.installing the DfuSe drivers that come shipped with it manually.Windows 10 Pro (and Manjaro on a Virtualbox VM).If you don’t use external clock, then this. This will divide input clock with 8 to get 1MHz on the input for PLL. In file systemstm32f4xx.c set PLLM value to match your crystal frequency (In MHz) In case of any STM32F4xx Discovery board, select PLLM 8. connect the STLink part of the board (CN1) to the PC via mini-USB-to-USB cable If you don’t use external crystal or clock, then you don’t need to change anything.The serial port associated with the ST-LINK on the board enumerated as COM28 on my PC and I was able to open it in TeraTerm and see serial output from my board. the boot0 pin is pulled up by bridging it with VDD I can get the port to work using code from mbed.I tried looking for a driver called "STM Device in DFU mode", but came across nothing official or hope-inspiring. And it doesn't show any "Available DFU Devices" in the respective drop down in DfuSe. However at around 3:45 when the device gets recognized as "STM Device in DFU mode", it doesn't for me. I tried following an official tutorial using DfuSe here: After installing both jumpers, the board shows 512KB free of. ![]() If the jumpers are removed, the USB interface is in 'ST-LINK' mode, and the NUCLEO virtual drive will show as about 20KB, and FULL. Verify the two jumpers are in place on CN2 (ST-LINK/NUCLEO). ![]() Then again, the F103 Nucleo does also not get recognized as DFU device (although I may not have had the proper boot pin up/down pulling with that one). I found the same problem with my NUCLEO-F401RE, even after following the directions above. It also is not recognized by the file system as mass storage, as opposed to a STM32F103 Nucleo-64 board that I've also tried, which was (on both Windows and Linux). Windows does show the board in the hardware manager, but it always shows it as "STM32 STLink". Now I've tried simply getting the board recognized as DFU device on both Linux and the Windows host machine, to no avail. (This happens on Manjaro inside Virtualbox on a Windows host) ST NUCLEO-F401RE User Manual (68 pages) Nucleo-64 boards. The MicroPython Github ReadMe has a walk through for the STMs but I keep failing at the deployment step where it keeps raising the value error 'No DFU device found'. We have 2 ST NUCLEO-F401RE manuals available for free PDF download: User Manual. I am trying to use Python on the STM32 micro controller family and am using the STM32F4 Discovery board with the STM32F429 MCU for experimentation.
