nRF9160 ERASEPROTECT INFORMATIONS

[Gioele]

Hi!
I have some troubles understanding the register Erase Protect and before using that I need to understand it more clearly.

I understood that if I activate that register I can't perform any more actions like erasing, flashing or writing code and if I'm not sure how to disable that, I couldn't have any more the possibility to work with the board.

How can I set the key on EraseProtect.disable and where should I insert that to disable the protection?

What is the "debugger" often mentioned in relation to the register Erase Protect?

What do you mean with debugger and firmware relating to nrf9160DK?

Hi,

There is a build-in debugger on the nRF9160DK that is used for debugging and programming. You can use nrfjprog for writing to a desired register.
Regarding firmware, you can read more about programming modem firmware and firmware development mode in the documentation.

Best regards,
Dejan

How can i use the debugger?

Hi,

The primary debug interface on the nRF9160 is the Segger OB Debugger which is available through USB connection. You can read more in the documentation.
You can connect to the board using regular USB connection and nrfjrpg tool from the command line.

Best regards,
