STM32MP157C - How to Trigger USB Boot mode from OpenSTLinux Firmware

[Dinesh K]

Hi ST Community,

We are using STM32MP157C-DK2 board and OpenSTlinux Firmware (v3.1-Openstlinux-5-4-dunfell-mp1-20-11-12) for our development. Currently for DFU from PC, we are triggering USB Boot mode by configuring Boot mode Switch (SW1) manually. But our product have a requirement to trigger USB boot mode from the running firmware automatically.

Is there any way to trigger USB Boot mode in STM32MP157C-DK2 board without any manual configuration ?
