The command uses the following structure:
nrfutil device otp-write [--force] [--file PATH] [--address ARG] [--value ARG] [--serial-number ARG] [--traits ARG] [--remote-jlink ARG] [--family ARG] [--x-force-device ARG] [--x-sdfw-variant ARG] [--append-batch PATH] [--generate] [--help]
| Long | Short | Values | Description |
|---|---|---|---|
--force |
- | Force writing the OTP memory This flag needs to be set in order for OTP memory to be written. |
|
--file |
PATH |
File containing OTP data (.hex, .ihex, .bin, .elf) Data outside the OTP memory range leads to an error. Values at OTP memory addresses not contained in the input file are not changed. If there is no OPT memory data at all in the file, the operation is aborted. If the input file is a .bin file, its start address is assumed to be the OTP memory address. |
|
--address |
ARG |
Address to write to when using --value to write a word to OTP memory The address needs to be within OTP memory. This flag cannot be combined with --file. |
|
--value |
ARG |
Word to write to OTP memory when using --address to specify an address within OTP memory This flag cannot be combined with --file. |
|
--serial-number |
ARG |
Select one or more devices based on a comma-separated list of serial numbers: --serial-number SN_1,SN_2,..,SN_n. | |
--traits |
ARG |
Select devices based on a comma-separated list of device traits: --traits TRAIT_1,TRAIT_2,... The list of device traits is treated as an OR filter. By default, all devices except for devices that only has the usb trait are enumerated and listed. List of available device traits: boardController Boardcontroller configuration broken Indicates a broken device devkit Device is a Nordic Semiconductor development kit jlink J-Link probes mcuBoot Device supports MCUboot modem Device supports modem nordicDfu Nordic USB devices with DFU trigger interface nordicUsb USB devices (with VendorID 0x1915) seggerUsb Segger USB devices (with VendorID 0x1366) serialPorts Device has serialports usb USB devices nrfutil device uses plugins to enumerate devices and apply device operations. The --traits option activates only the plugins that control the specified traits. Some trait combinations in --traits might therefore make some operations or trait annotations unavailable for devices that should have supported these operations or traits. |
|
--remote-jlink |
ARG |
Select one or more remote J-Link probes: --remote-jlink HOST_1[:PORT_1],HOST_2[:PORT_2],..,HOST_n[:PORT_n] For more information about how to set up a J-Link Remote Server, see https://kb.segger.com/J-Link_Remote_Server. The connection information passed in this flag is used to connect to the J-Link Remote Server instance, and the remote probe is then treated in the same way as a locally connected device. |
|
--family |
ARG |
Set the expected device family for the automatic device detection The operation will fail if the expected device family does not match the device family of the connected device. |
|
--x-force-device |
ARG |
(Experimental) Provide device name to override automatic device identification The command uses the provided device name to look up the corresponding device in the internal database. If found, the latest known hardware revision is selected. The option is case-insensitive. Compared to when it is not used, the option ignores hardware registers used to identify the device. The device name is for example nRF54L15. Use the nrfutil device device-info command to list the device name of your connected device.CAUTION: Make sure that the device identification override matches the connected device. If there is a mismatch (for example forcing nRF5340 identification for the nRF9160 SiP), you are risking bricking the device. |
|
--x-sdfw-variant |
ARG |
Select the Secure Domain Firmware (SDFW) variant that is running on the device If not specified, the tool assumes that the IronSide Secure Enclave firmware is running on the device. |
|
--append-batch |
PATH |
Append the operation to the given batch file instead of running it When this option is set, the command records the operation as JSON in the batch file and exits without performing the operation on a device. The generated batch file can then be executed on devices using nrfutil device batch-execute --batch-file <file_path>.This flag cannot be used in combination with other device selection options, such as --serial-number, --traits, or --remote-jlink. |
|
--generate |
-g |
- | Show the JSON definition of the operation. |
--help |
-h |
- | Print help (see a summary with '-h') |
