+tftpput command
+===============
+
+Synopsis
+--------
+
+::
+
+    tftpput address size [[hostIPaddr:]filename]
+
+Decription
+----------
+
+The tftpput command is used to transfer a file to a TFTP server.
+
+By default the destination port is 69 and the source port is pseudo-random.
+If CONFIG_TFTP_PORT=y, the environment variable *tftpsrcp* can be used to set
+the source port and the environment variable *tftpdstp* can be used to set
+the destination port.
+
+address
+    memory address where the data starts
+
+size
+    number of bytes to be transferred
+
+hostIPaddr
+    IP address of the TFTP server, defaults to the value of environment
+    variable *serverip*
+
+filename
+    path of the file to be written. If not provided, the client's IP address is
+    used to construct a default file name, e.g. C0.A8.00.28.img for IP address
+    192.168.0.40.
+
+Example
+-------
+
+In the example the following steps are executed:
+
+* setup client network address
+* load a file from the SD-card
+* send the file via TFTP to a server
+
+::
+
+    => setenv autoload no
+    => dhcp
+    BOOTP broadcast 1
+    DHCP client bound to address 192.168.1.40 (7 ms)
+    => load mmc 0:1 $loadaddr test.txt
+    260096 bytes read in 13 ms (19.1 MiB/s)
+    => tftpput $loadaddr $filesize 192.168.1.3:upload/test.txt
+    Using ethernet@1c30000 device
+    TFTP to server 192.168.1.3; our IP address is 192.168.1.40
+    Filename 'upload/test.txt'.
+    Save address: 0x42000000
+    Save size:    0x3f800
+    Saving: #################
+         4.4 MiB/s
+    done
+    Bytes transferred = 260096 (3f800 hex)
+    =>
+
+Configuration
+-------------
+
+The command is only available if CONFIG_CMD_TFTPPUT=y.
+
+CONFIG_TFTP_BLOCKSIZE defines the size of the TFTP blocks sent. It defaults
+to 1468 matching an ethernet MTU of 1500.
+
+If CONFIG_TFTP_PORT=y, the environment variables *tftpsrcp* and *tftpdstp* can
+be used to set the source and the destination ports.
+
+CONFIG_TFTP_WINDOWSIZE can be used to set the TFTP window size of transmits
+after which an ACK response is required. The window size defaults to 1.
+
+If CONFIG_TFTP_TSIZE=y, the progress bar is limited to 50 '#' characters.
+Otherwise an '#' is written per UDP package which may decrease performance.
+
+Return value
+------------
+
+The return value $? is 0 (true) on success and 1 (false) otherwise.
