In the STM32MP157C to go to the DFU mode is it necessary that the Vbus pine is connected or can it be done via the firmware??

Hi,

I confirm BootROM does not need neither VBUS nor ID pins to work in DFU mode.

For uBoot and Kernel, please see DT settings in https://wiki.st.com/stm32mpu/wiki/How_to_configure_U-Boot_for_your_board#USB_OTG_node

Regards.
