--jdll <file> instead of searching for the latest version of Segger's JLinkARM dll.
--ini <file> not nrfjprog.ini file in the installation folder.
--qspiini <file> Uses the QSPI settings file not QspiDefault.ini file in the installation folder. Must be combined with --erasepage, --memrd, --memwr, --program, --verify, --readqspi or --qspieraseall operation is not available for devices without a QSPI peripheral.
--qspicustominit Use the QSPI custom instructions defined in the QSPI settings file used in the operation when initializing the QSPI peripheral. see QSPIDefault.ini . Must be combined with either --memrd, --memwr, --program, --verify, --erasepage or --qspieraseall commands. not available for devices without a QSPI peripheral.
-f --family <family> Selects the device family for the operation. Valid argument options are NRF51, NRF52 and UNKNOWN. UNKNOWN automatic family detection is performed. providing the actual family is faster than performing the automatic family detection. If --family option is not given, the default is taken from nrfjprog.ini.
-s --snr <serial_number> Selects the debugger with the given serial number among all those connected to the PC for the operation. Must be combined with another command.
-c --clockspeed <speed> Sets the debugger SWD clock speed in kHz resolution for the operation. The valid clockspeed arguments go from 125 kHz to 50000 kHz. If given clockspeed is above the maxiumum clockspeed supported by the emulator, its maximum will be used instead. If --clockspeed option is not given, the default is taken from nrfjprog.ini. Must be combined with another command.
--recover Erases all user available non-volatile memory and disables the read back protection mechanism
--rbp <level> Enables the ReadBack Protection mechanism. Valid argument options are CR0 and ALL. Limitations: For nRF52 devices, the CR0 argument option is invalid. Side effects: After an --rbp operation is performed, the available operations are reduced. For nRF51 devices, and if argument option ALL is used, --pinreset will not work on certain older devices. For nRF52 devices, only --pinreset, --debugreset or --recover operations are available after --rbp.
--pinresetenable Enables the pin reset by the use of UICR PSELRESET registers. nRF51 , not available.
-p --pinreset Performs a pin reset. Core will run after the operation.
-r --reset Performs a soft reset by setting the SysResetReq bit of the AIRCR register of the core. The core will run after the operation. Can be combined with the --program operation. If combined with the --program operation, the reset will occur after the flashing has occurred to start execution.
-d --debugreset Performs a soft reset by the use of the CTRL-AP. The core will run after the operation. Can be combined with the --program operation. If combined with the --program operation, the debug reset will occur after the flashing has occurred to start execution. nRF51 not available. For nRF52 not available for nRF52832_xxAA_ENGA devices.
-e --eraseall Erases all user available program flash memory and the UICR page. Can be combined with the --qspieraseall operation. nRF51 :, if the device came from Nordic with a pre-programmed SoftDevice, only the user available code flash and UICR will be erased.
--qspieraseall Erases all the flash of the external memory device with the help of the QSPI peripheral. Note that depending on the external memory device's erase speed the operation might take minutes. Can be combined with the --eraseall operation. nRF51 not available. nRF52 not available for devices QSPI . nRF52 devices, the operation is only available for devices connected to an external memory device. To determine if an external memory device is connected, nrfjprog checks MemSize parameter from the QspiDefault.ini file or the QSPI configuration ini file that is given with the --qspiini option.
--eraseuicr Erases the UICR page. nRF51 : the operation is available only if the device came from Nordic with a pre-programmed SoftDevice.
--erasepage <start[-end]> Erases the flash pages starting at the flash page containing the start address and ending at the page containing the end address (not included in the erase). If end address is not given, only one flash page will be erased. If your device is equipped with a QSPI peripheral, the pages to erase belong to the XIP region of the device, and an external memory device is present, this command erases 4 kB pages from the external memory device. The first address of the region is considered as address 0 of the external memory device. To determine if an external memory device is present, nrfjprog checks the MemSize parameter from the QspiDefault.ini file or from the QSPI configuration ini file given with the --qspiini option. nRF51 :, the page will not be erased if it belongs to region 0.
--program <hex_file> [--sectorerase | --chiperase | --sectoranduicrerase] [--qspisectorerase | --qspichiperase] Programs the specified hex_file into the device. If the target area to program is not erased, the --program operation will fail unless an erase option is given. Valid erase operations for the internal flash memory are --sectorerase, --sectoranduicrerase and --chiperase. --chiperase , all the available user non-volatile memory, including UICR, will be erased --sectorerase , only the targeted non-volatile memory pages excluding UICR will be erased. --sectoranduicrerase , only the targeted non-volatile memory pages including UICR will be erased.
--sectoranduicrerase and --sectorerase operations normally take significantly longer time compared to --chiperase operation so use them with caution. If your device is equipped with a QSPI peripheral and an external memory device is present, data targeting the XIP region will be written to the external memory device. The first address of the XIP region is considered as address 0 of the external memory device. To determine if an external memory device is present, nrfjprog checks the MemSize paramter from QspiDefault.ini file or from the QSPI configuration ini file given with the --qspiini option. If the target area to program is not erased, the --program operation will fail unless an erase option is given. Valid erase operations for the external memory device are --qspichiperase and --qspisectorerase. If --qspichiperase is given, the external memory device will be erased. If the --qspisectorerase is given, only 4kB pages pages from the targeted external memory device will be erased. Note that --qspichiperase operation may take several minutes. The --program command can be combined with the --verify operation. It can also be combined with either the --reset or the --debugreset operations. the reset will occur after the flash operation in order to start the execution. : nRF51 --sectoranduicrerase is not available. if the hex_file provided contains sectors belonging to region 0, the --program operation will fail. --qspisectorerase and --qspichiperase operations are not available. nRF52 --qspisectorerase and --qspichiperase operations are not available unless the device is equipped with a QSPI peripheral and an external memory is connected. To determine if an external memory is present, the MemSize parameter from QspiDefault.ini file or from the QSPI configuration ini file given with the --qspiini option is evaluated.
--memwr <addr> --val <val> Writes to the provided address in memory with the help of the NVM Controller or, if your device is equipped with a QSPI peripheral and the address to write belongs to the XIP region, with the help of the QSPI peripheral to an external memory device. To determine if an external memory device is present, nrfjprog checks the MemSize parameter from QspiDefault.ini file or the QSPI configuration ini file that is given with the --qspiini option. The first address of the region is considered as address 0 of the external memory device. If the target address is flash (either internal or in the external memory device) and not erased, the operation will fail. This command can be combined with the --verify operation.
--ramwr <addr> --val <val> Writes to memory without the help of the NVM Controller to the provided address. If the target address is in non-volatile memory, --ramwr will have no effect unless the non-volatile memory controller (NVMC) has been previously configured by the user for a write operation. Can be combined with the --verify operation.
--verify [<hex_file>] [--fast] The provided hex_file contents are compared with the contents in the device code flash, RAM, UICR and XIP regions for devices equipped with a QSPI peripheral connected to an external memory device, and fail if there is a mismatch. To determine if an external memory device is present, nrfjprog checks MemSize parameter from QspiDefault.ini file or from the QSPI configuration ini file given with the --qspiini option. If the optional --fast parameter is given, nrfjprog will calculate a hash of the flash target area using a sha256 algorithm and compare it to the expected hash instead of reading back the actual contents of the device's flash in order to speed the operation. It can be combined with the --program, --memwr and --ramwr operations if provided without the hex_file parameter. nRF51 , --fast verifying is not available.
--memrd <addr> [--w <width>] [--n <n>] Reads n bytes from the provided address. If width is not given, 32-bit words will be read if addr is word aligned, 16-bit words if addr is half word aligned, and 8-bit words otherwise. If n is not given, one word of size width will be read. address and n must be aligned to the width parameter. maximum number of bytes that can be read is 1 MB. width must be 8, 16 or 32. If your device is equipped with a QSPI peripheral, and the addresses to read belong to the XIP region, the QSPI peripheral is used to read from the external memory device . To determine if an external memory device is present, mrfjprog checks the MemSize parameter from QspiDefault.ini file or the QSPI configuration ini file that is given with the --qspiini option. The first address of the region is considered as address 0 of the external memory device. A single --memrd instruction cannot be used to read addresses from both the external memory device and the nRF device.
--halt Halts the CPU core.
--run [--pc <pc_addr> --sp <sp_addr>] Starts the CPU. If --pc and --sp options are given, the pc_addr and sp_addr are used as initial PC and stack pointer. For pc_addr to be valid its last bit must be one. For sp_addr to be valid it must be word aligned.
--readuicr <file> Reads the device UICR and stores it in the given file name. Can be combined with --readram, --readcode and --readqspi. only one instruction can provide a file name.
--readcode <file> Reads the device flash and
--readram <file> Reads the device ram and
--readqspi <file> Reads the QSPI-connected external memory and
--readregs Reads the cpu registers.
--licenses Displays the licenses of the open source modules used in nrfjprog.exe.
-q --quiet Reduces the stdout info. Must be combined with another command.
-h --help
-i --ids Displays the serial numbers of all the debuggers connected to the PC.
-v --version Displays the nrfjprog and dll versions.
