How to "burn" MicroPython in STM board NUCLEO-H743ZI2

Post by MickPF » Fri Jan 22, 2021 10:06 am

Hi,

Since some days I try to find a working tool to burn Micropython (a DFU file) in this board via USB, and any tool (DFUse demo, dfu-util and much more) doesn't work, because they recognize/see only the STLink-V3 device (vendorID=0x0483, productID=0x374E), but not the device behind it, and "say" "No applicable device found".

Can anybody help me?

Thanks in advance,
Michael

The USB port that connects to the STLink processor is on one end of the board.

The USB connector on the other end of the board is the one that connects directly to the MCU and this is the one that would be used for DFU mode.

If you use the deploy-stlink target then it will program the firmware via the STLink MCU.

If you use the deploy target then it will use DFU mode and requires that your MCU be in DFU mode and connected to your PC via the USB connector on the other end of the board.
