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.
