8> --erasepage
--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.
Limitations:
For nRF51 devices, the page will not be erased if
it belongs to region 0.

D:\Project\SES\nrfutil> nrfjprog
Usage:
-------------------------------------------------------------------------------
-q --quiet Reduces the stdout info. Must be combined with
another command.
-h --help Displays this help.
-v --version Displays the nrfjprog and dll versions.
--log [<path>] Enable logging.
Default output file is "log.log".
Set the <path> option to modify log file
location and/or name.
If the parent folder of <path> does not
yet exist, nrfjprog will attempt to create it.
Logger output is always appended
to the file.
Must be combined with another command.
--jdll <file> Uses the Segger's JLinkARM dll specified in the
given file path instead of searching for the
latest version of Segger's JLinkARM dll. Must be
combined with another command.
Limitations:
Unicode paths are not supported
--ini <file> Uses the nrfjprog settings file specified in the
given file path instead of searching for the
default nrfjprog.ini file in the installation
folder. Must be combined with another command.
--qspiini <file> Uses the QSPI settings file specified in the given
file path instead of searching for the default
QspiDefault.ini file in the installation folder.
Must be combined with either --erasepage, --memrd,
--memwr, --program, --verify, --readqspi or
--qspieraseall commands.
Limitations:
For nRF51 devices, the operation is not available.
For nRF52 devices, the operation is not available
for devices without a QSPI peripheral.
For nRF91 devices, the operation is not available
--qspicustominit Deprecated, this operation does nothing.
-i --ids Displays the serial numbers of all the debuggers
connected to the PC.
--com Displays a list of the serial port associated
with all connected debuggers. If combined with
--snr, it will display all comports associated
with this debugger
--deviceversion Displays the type of device connected.
If combined with --snr, it will display the device
associated with this debugger
-f --family <family> Selects the device family for the operation. Valid
argument options are NRF51, NRF52, NRF53, NRF91,
and UNKNOWN.
If UNKNOWN family is given, an automatic family
detection of the device is performed. Note that
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. Must be combined with another
command.
-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 if
enabled.
--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.
Limitations:
For nRF51 devices, the command is not available.
For nRF53 devices, the command is not available.
For nRF91 devices, the command is 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.
Limitations:
For nRF51 devices, the --debugreset operation is
not available.
For nRF52 devices, the --debugreset operation is
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.
Limitations:
For nRF51 devices, 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.
Limitations:
For nRF51 devices, the operation is not available.
For nRF52 devices, the operation is not available
for devices without a QSPI peripheral.
For 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.
For nRF91 devices, the operation is not available
--eraseuicr Erases the UICR page.
Limitations:
For nRF51 devices, the operation is available only
if the device came from Nordic with a
pre-programmed SoftDevice.
For nRF91 devices, the operation is not available
to erase uicr, please use --eraseall
--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.
Limitations:
For nRF51 devices, the page will not be erased if
it belongs to region 0.
--program <hex_file> [--sectorerase | --chiperase | --sectoranduicrerase |
--recover] [--qspisectorerase | --qspichiperase]
Programs the specified image_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 --recover,
--sectorerase, --sectoranduicrerase and
--chiperase. If --chiperase is given, all the
available user non-volatile memory, including
UICR, will be erased before programming. If
--recover is given, all the available user
non-volatile memory, including UICR, will
be erased before programming, even if the
device is readback protected.
If --sectorerase is given, only the targeted
non-volatile memory pages excluding UICR will
be erased. If --sectoranduicrerase is given,
only the targeted non-volatile memory pages
including UICR will be erased. Note that the
--sectoranduicrerase and --sectorerase
operations normally take significantly longer time
compared to --chiperase operation so use them with
caution. If your device is equipped witha 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.
Limitations:
For nRF51 devices, the --sectoranduicrerase
operation is not available.
For nRF51 devices, if the image_file provided
contains sectors belonging to region 0, the
--program operation will fail.
For nRF51 devices, the --qspisectorerase and
--qspichiperase operations are not available.
For nRF52 devices, the --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.
For nRF91 devices, the --qspisectorerase and
--qspichiperase operations are not available.
--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 [<image_file>] [--fast] The provided image_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 image_file
parameter.
Limitations:
For nRF51 devices, the --fast verifying option
is not available
For nRF91 devices, the --fast verifying option
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. The address and
n must be aligned to the width parameter. The
maximum number of bytes that can be read is 1 MB.
The 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 if present. 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.
Limitations:
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. If combined, only one
instruction can provide a file name.
--readcode <file> Reads the device flash and stores it in the given
file name. Can be combined with --readuicr,
--readram and --readqspi. If combined, only one
instruction can provide a file name.
--readram <file> Reads the device ram and stores it in the given
file name. Can be combined with --readuicr,
--readcode and --readqspi. If combined, only one
instruction can provide a file name.
--readqspi <file> Reads the QSPI-connected external memory and
stores it in the given file name. Can be combined
with --readuicr, --readcode and --readram. If
combined, only one instruction can provide a file
name.
--readregs Reads the cpu registers.
--coprocessor <coprocessor> Connects the device to the
selected coprocessor. Valid arguments are
CP_APPLICATION, CP_MODEM and CP_NETWORK.
If --coprocessor option is not used,
CP_APPLICATION will be the target of the other
operation. Must be combined with another command.
Limitations:
For NRF51 devices, the -- coprocessor operation is
not available.
For NRF52 devices, the -- coprocessor operation is
not available.
