devzone.nordicsemi.com/.../ble_5F00_dfu_5F00_unbonded.c devzone.nordicsemi.com/.../ble_5F00_dfu.cYes I am using custom board. I am attaching ble_dfu.c and ble_dfu_unbounded.c files of my application code. i have not make any changed in both files. One more thing , What is the need of making reset pin low during jumping from application to bootloader?

Are you using a custom board or the Development kit? It might be that P0.21 is held high for some reason when you try going from application to bootloader. Could you show me the snippet of your code that makes the application go to the bootloader?

Best regards,

Simon

Can you confirm that the macro is "CONFIG_GPIO_AS_PINRESET"?
Yes, the macro is "CONFIG_GPIO_AS_PINRESET".

What GPIO(s) have you configured as reset pins?
I have configured pin P0.21 as reset pin.

Are GPIO(s) configured to the same pins in the bootloader and application?
Yes, i have configured P0.21 as reset pin in both bootloader and application code.
