Hello, I need more details on DFU mode entering topic. I understand how to configure DFU to enter the bootloading mode on button press event but have dilemma about using the P1 port pins caused by description of NRF_BL_DFU_ENTER_METHOD_BUTTON configuration option: "32 - 32 (P1.0) (Software Component only)" . Could these pins be used to enter the bootloading mode and what are constraints in their usage? What is the meaning of note "Software Component only" in pin option description? For more detailes please refer to DFU mode section of Bootloader and DFU modules on https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.0.0%2Flib_bootloader_dfu_banks.html, NRF_BL_DFU_ENTER_METHOD_BUTTON option.

Hi,

Yes, you can use P1 pins (on SoCs where they are available).

The "Software Component only" comment seems to be erroneously generated, and I have reported the documentation bug in our internal tracker.
