nRF Command Line Tools Desktop tool

Cross-platform desktop software

The nRF Command Line Tools is used for development, programming and debugging of Nordic Semiconductor's nRF51, nRF52, nRF53 and nRF91 Series devices.

Important: The nRF Command Line Tools is in the process of being archived. nRF Command Line Tools will remain available for download, but will gradually be replaced by nRF Util. You can download and start using nRF Util here. Consider downloading both in the transition period.

Components:
  • SEGGER J-Link software and documentation pack
  • mergehex executable - enables you to combine up to three .HEX files into one single file
  • nrfjprog DLL - a DLL that exports functions for programming and controlling nRF51, nRF52, nRF53 and nRF91 Series devices and lets developers create their own development tools using the DLLs API
  • nrfjprog executable - tool for programming through SEGGER J-LINK programmers and debuggers - nrfjprog is officially deprecated and is being replaced by nRF Util. This affects the nRF Connect SDK v2.8.0, where nrfjprog will be removed in an upcoming release. Use nRF Util for all related tasks going forward.

HIGHLIGHTS:

  • nrfjprogdll: Support new Modem FW bootloader filenames introduced in MFW v2.
  • nrfjprogdll: Fix memory control parameter for NRFJPROG_write_u32 on nRF54.

    - (Release) Update bundled Segger installers and tar balls to v7.50a

    - (nrfjprog.exe) Made --coprocessor flag with CP_APPLICATION as the argument available for all devices.
    - (nrfjprog.exe) When an error condition occurs, nrfjprog.exe now prints the last error messages from nrfjprog.dll as part of the error output if logging is enabled.
    - (nrfjprog.exe) Fixed issue where not all memory layouts were correctly discovered.
    - (nrfjprog.exe) --program no longer checks if flash is erased before writing in order to improve performance. The user can append option "--verify" to check memory after write operation.
    - (nrfjprog.exe) --program can now be used perform modem firmware upgrade using debugger on nRF91 devices by passing the modem firmware .zip file as argument.
    - (nrfjprog.exe) Added field "RetainRAM" to QSPI ini file.

    - (nrfjprog.dll) Quality of life improvements to coprocessor management functions.
    - (nrfjprog.dll) Add QSPI management functions.
    - (nrfjprog.dll) Add highlevel program, read_to_file, erase, and verify functions.
    - (nrfjprog.dll) Add support for managing multiple J-Link connections. See NRFJPROG_*_inst functions.
    - (nrfjprog.dll) Removed implementation of deprecated function NRFJPROG_is_ram_powered, deprecated since 9.2.0. The function now returns NOT_IMPLEMENTED_ERROR.
    - (nrfjprog.dll) New error return codes.

    - (highleveldll) Add NRFJPROG_*probe_init_ex functions that use msg_callback_ex with an optional argument param instead of log_callback. This allows easier logging of multiple probe instances.
    - (highleveldll) Added support for pipelined updates of nrf9160 modem in supported bootloaders.
    - (highleveldll) When using NRFJPROG_*probe_init_ex constructors, SWD-based probe connections can now set clock speeds manually.
    - (highleveldll) NRFJPROG_program() no longer checks if flash is erased before writing in order to improve performance. Enable verification to check result after writing.

    - (pynrfjprog) APIError now contains the last error messages reported from the dll if logging is enabled.
    - (pynrfjprog) Removed deprecated function NRFJPROG_is_ram_powered, deprecated since 9.2.0
    - (pynrfjprog) Drop support for deprecated Python versions 2.7, 3.4, and 3.5
    - (pynrfjprog) MultiAPI.MultiAPI is now deprecated and will be removed in a future major version of pynrfjprog. It redirects to LowLevel.API that fulfills the same purpose.
    - (pynrfjprog) HighLevel: DebugProbe and IPCDFUProbe constructors can set SWD clock speed through keyword argument clock_speed.
    - (pynrfjprog) LowLevel.py: Updated with new functions from nrfjprog.dll, adding program_file(), read_to_file(), verify_file(), erase_file(),
                        qspi_init_ini(), qspi_start(), qspi_configure() and qspi_configure_ini.
    - (pynrfjprog) Update JLink.py find_latest_jlink script to support windows installs with J-Link sw pack installs in both program files and program files(x86)

    - (warning) Please note, it is now more important than before to always explicitly close a connection using the appropriate function call. 
                Failure to properly clean up a session will lead to leftover jlinkarm_nrf_worker processes remaining in the system. 
                This may prevent your program from exiting. This may also prevent future nrfjprog or J-Link sessions from working correctly.

      • Fixed issue there if SECURE readbackprotection was enabled, NRFJPROG_read(), NRFJPROG_read_u32(), NRFJPROG_write(), and NRFJPROG_write_u32() would fail with NOT_AVAILABLE_BECAUSE_PROTECTION even though the operation was possible.
