STM32MP157C-DK2 No STM32 device in DFU mode connected

[RMarg]

Hello,

I try to work with a STM32MP157C-DK2 board but I'm not able to detect the board.

I'm on Ubuntu 18.04, I've follow the STM32MP1 wiki and install everything needed.

I put the board in DFU mode (BOOT 2 & 0 on 0) but when I run STM32_Programmer_CLI -l usb I get No STM32 device in DFU mode connected.

I've aslo tried with an STM32MP157A-DK1 and the same thing happened.

I Currently use a 5.1V 2a power supply because I've nothing else for the moment and the usb OGT isn't plug. Do you thing that could be the cause of my problem ?

I've been stuck for days with this issue, thanks for your help.

So I confirm that 5v 3a power supply and USB OTG must be provide to detect STM32MP157C-DK2 in DFU mode. It was my mistake but I hope my negligence could help someone in the future.
