 write command
 =============
 
-See :doc:`read`.
+Synopsis
+--------
+
+::
+
+    write <interface> <dev[:part|#partname]> <addr> <blk#> <cnt>
+
+Description
+-----------
+
+The write command can be used for raw writing data to a block device
+(or partition therein), i.e. without going through a file system.
+
+The block device is specified using the <interface> (e.g. "mmc") and
+<dev> parameters. If the block device has a partition table, one can
+optionally specify a partition number (using the :part syntax) or
+partition name (using the #partname syntax). The command then reads
+the <cnt> blocks of data starting at block number <blk#> of the given
+device/partition to the memory address <addr>.
+
+Examples
+--------
+
+.. code-block:: bash
+
+    # Write to the third sector of the partition named 'bootdata' of mmc device 0
+    write mmc 0#bootdata $loadaddr 2 1
+
+Configuration
+-------------
+
+The write command is only available if CONFIG_CMD_WRITE=y.
+
+Return value
+------------
+
+The command sets the return value $? to 0 (true) on success and to 1 (false) in
+case of an error.
