Ok thanks for the quick answer !

What I'm facing now is that my mcu goes into boot mode even if i press my button less than

CONFIG_BOOT_USB_DFU_DETECT_DELAY.

It seems that it doesn't have any effect on the button detection.

Do you have any idea why ?

Kinds regards.

Martin

Hello Martin,

You can call sys_reboot(0); to reset into the bootloader. To use this function, you simply include <zephyr/sys/reboot.h> in your source file and select CONFIG_REBOOT in your project configuration file. But you also need a way to signal the bootloader to enter serial recovery mode and not boot back into the application after the reset.

Here are the different entry modes which are implemented in the bootloader: https://github.com/nrfconnect/sdk-mcuboot/blob/b3e3ce39f3e1abd95ff4010263b3613edf59dd54/boot/zephyr/Kconfig.serial_recovery#L147

Best regards,
