NAME
       nvme-rpmb-write-config - Write the RPMB device configuration block

SYNOPSIS
       nvme [<global-options>] rpmb write-config <device>
                               [--msgfile=<data-file> | -f <data-file>]
                               [--msg=<data> | -d <data>]
                               [--keyfile=<key-file> | -g <key-file>]
                               [--key=<key> | -k <key>]

DESCRIPTION
       Writes 512 bytes of device configuration block data to RPMB target 0 of
       the NVMe device, authenticated with the key previously programmed with
       nvme rpmb program-key.

       The <device> parameter is mandatory and an NVMe character device (ex:
       /dev/nvme0) must be specified.

OPTIONS
       -k <key>, --key=<key>, -g <key-file>, --keyfile=<key-file>
           Authentication key previously programmed with nvme rpmb program-key
           for target 0. The key can be specified on the command line using
           --key or -k, or read from a file using --keyfile or -g.

       -f <data-file>, --msgfile=<data-file>
           Name of the file the configuration block data is read from.

       -d <data>, --msg=<data>
           Provides the configuration block data directly on the command line,
           instead of reading it from a file.

GLOBAL OPTIONS
       The following options are defined at the top-level nvme command and are
       available to this subcommand:

       --dry-run
           Print the command that would be executed, but do not actually
           execute it.

       --no-ioctl-probing
           Disable probing for 64-bit IOCTL support.

       --no-retries
           Disable retry logic on transient errors.

       -o <fmt>, --output-format=<fmt>
           Set the reporting format to normal, tabular, 'json, or binary. Only
           one output format may be used at a time.

       --output-format-version=<version>
           Select the output format version. Version 1 uses the original field
           naming, while version 2 (default) provides more consistent and
           script-friendly field names.

       --timeout=<ms>
           Set the timeout for the command in milliseconds.

       -v, --verbose
           Increase the level of detail in the output. May be specified
           multiple times to further increase verbosity.

       These options can also be set as machine-wide defaults in
       nvme-cli.conf(5). A command-line flag always overrides the file.

EXAMPLES
       o   Write configuration data block from config.bin file

               # nvme rpmb write-config /dev/nvme0 -f config.bin -k 'SecretKey'
