Question ODESC V4.2 DFU not working

I bought an Odesc V4.2 board, and it's not entering DFU mode.
In normal mode, my computer detects two entries with the name ODRIVE 3.6 Native Interface and one serial port.
When I switch to DFU mode, the computer makes the sound as if something is being disconnected from the USB, and it doesn't connect anymore.(softlock, resets when pressing reset again, and goes backto normal mode)
What could be the issue? When I try to connect through onedrivetool, it connects and shows the firmware (v0.0.0), but I can't give the DFU activation command through the program. Does anyone know what can be done?

This boards do not have dedicated switch or jumper but have special button:

• Connect board to PC via USB cable.
• Connect external power. Controller will boot in normal mode.
• Press and hold BOOT button.
• Press RESET button - controller will reboot in DFU mode.
• Flash firmware
• Press RESET button - controller will boot in normal mode.

Plug the power with PRESSED boot button

I also have the same problem, I already followed the instructions but without success.

Do I need to press the buttons for a specific time?

Hi,
sometimes I am testing new actuator- concepts with the Odesc 4.2 board.
You can Flash the firmware Super easy with a cheap st-link v2 and the stm32-stlink- Utility Software. Youtube will show you how to do.
By the way: the Odesc 4.2is a great piece of Hardware!
And in the Odrivetool you have to call it dev0 instead of odrv0

Hi,

Thanks for the tip.

How is the connection made between the st-link and the odesc?
