Locking the Device Debug Port and enabling the Access Port Protection
Once the access port protection is enabled, no further access including
debugging can be done anymore!
To ensure that the device debug port is locked during production programming and the access
port protection is enabled correctly, the following steps must be followed.
1. Use the Microcontroller Development Kit (MDK)
application development.
–
If the application is based on
the application with the globally defined ENABLE_APPROTECT-define.
Open the project in Segger Embedded Studio. Set the define in Project
options > Section Code > Preprocessor Options > Preprocessor Definitions.
–
If the application is based on
compile the application with the option set CONFIG_NRF_APPROTECT_LOCK=y, for
example in the project configuration file prj.conf.
2. Use the nRF Command Line Tools (version 10.15.4)
Please make sure to use version 10.15.4 or later.
3. Execute nrfjprog.exe --verify fast --sectorerase --program
application.hex from a command line prompt to program an application HEX file:
Parsing image file.
Verifying programming.
Verified OK.
4. Execute nrfjprog.exe --rbp ALL from a command line prompt to enable the
access port protection:
Protected the device against read and debug. Only a
--recover, --debugreset, or --pinreset operations will work from
now on.
