nrf-recover

Unlocks nRF52 devices using a CMSIS-DAP or JLink probe.

Installation

Using cargo:

$ cargo install nrf-recover

Usage

This utility uses probe-rs to interface with the debug probe, probe-rs requires libusb and udev rules properly configured.

Connect your microcontroller to the debug probe and run:

$ nrf-recover

This process has a timeout of 15 seconds, but it usually completes in less than one second. If you get a timeout, you should reset the microcontroller and try again. Please open an issue if you can not unlock the chip after several tries.

Attention: This process will erase the entire code flash and UICR area of the device, in addition to the entire RAM.
