STM32MP257-EV1 in DFU mode

[faye_Lee]

Hello,

   How could STM32MP257-EV1 in DFU mode,

    I have followed the steps of STM32MP25 Evaluation boards - Starter Package for Android - stm32mpu,

1. install SetupSTM32CubeProgrammer_win64.exe

2. Run the “STM32 Bootloader.bat”

3. Set the boot switches to the off position (boot from UART/USB).

4. Connect the USB type-C (OTG) port (4) to the host PC that contains the downloaded image.
5. Insert the delivered microSD card into the dedicated slot (5).
6. Connect the USB type-C (power supply) port (1) to the power connector or a host PC, and check the power jumper position.
7. Press the reset button (7) to reset the board.

but when I check device manager, nothing new shows up at all.

hi @faye_Lee 

LD6 should be green (or orange).

Seems to be OFF on your picture.

This mean the supply/PC connected on CN21 has not been recognized as a valid USB Type-C supply (required to have the 5V supply being applied to the rest of the board).

Hi PatrickF,

   So could I connect  5V adapter to CN21? Do I need to remove step6( Connect the USB type-C (power supply) port (1) to the power connector or a host PC, and check the power jumper position.)?

What document is it of this picture, could you share with me?Thank you

Yes, a 5V-12V 15W adapter is accepted on CN20, need JP4 to be moved to the other position.
