Default bootloader and its capabilities

[RobbLev]

I have a few questions about the bootloader of the nRF52.

I used "nrfjprog --eraseall" to erase the chip, afterwards I turned the power off and on again while holding down the RESET button.

I see it entered a bootloader mode but I have erased the chip so I'm assuming there is a default bootloader it is running?

what is this bootloader and is there any way to enter DFU mode with it?

Thanks,

Robbie

Hello,

nrfjprog --eraseall will erase the entire program memory on the nRF52 so there won't be any bootloader or application code left. Pressing the  reset button on power up will actually make the Interface MCU enter bootloader mode.
