+
+The RTEMS Tester contains a TFTP server so an external TFTP is not
+needed. It is recommended a TFTP Proxy is set up to handle the TFTP
+sessions for your network. The internal TFTP server ignores the
+requrest file and serves the next executable. If the target requires
+the executable ne in a specific format provide a script via the
+``target_pretest_command`` option in your user configuration file.
+
+The RTEMS Tools provides a TFTP protocol proxy server. It takes a list
+of MAC addresses and proxies TFTP sessions for that MAC address to
+another IP address and port. A proxy provides the following benefits:
+
+1. The TFTP proxy server is the only software required to run as root
+
+2. All hardware targets can be configured to serve from a single
+ machine and the proxy can distribute the sessions out to developer
+ machines
+
+3. There is no need to provide a globally writable file system a
+ central TFTP server acceses
+
+If you have a central TFTP server refer to the ``%wait`` directive.

+Wait
+~~~~
+
+The ``%wait`` directive waits the timeout period for a test to
+complete. The directive monitors the console output and resets the
+timeout timer if console output is seen. If the test runs for too long
+while outputing data an error is reported.
+
+The wait directive can be used in systems where there is an external
+mechanism being used to send the executable to the target hardware.
+
+An example is::
+
+ %wait
+
+Wait has no options. The timeouts are controlled in other ways.
+
+If you have an external system wide TFTP server with global access
+wait can used by providing a `` script that places the file in the
+location the TFTP server can see. This is done as the test start so if
+networking loading there is normally enough time to get the executable
+image in place before the transfer starts. The MVME2700
+(``powerpc/mvme2307``) is a BSP that supports the ``%wait`` directive.
+
+The following is an example user configuration file (see
+``--user-config``)::
+
+ #
+ # MVME2700 (mvme2307)
+ #
+ [mvme2307]
+ bsp_tty_dev = 1.2.3.4:5678
+ target_pretest_command = mk-mvme2307-img @EXE@ /tftp/cjohns/rtems.img
+ target_exe_filter = /\.exe/.exe.img/
+ target_on_command = pw-ctl 1.2.3.4 toggle-on 3 1
+ target_off_command = pw-ctl 1.2.3.4 off 3
+ target_reset_command = pw-ctl 1.2.3.4 toggle-on 3 1
+
+The script ``mk-mvme2307-img`` converts the RTEMS ELF executable into
+the PowerPC prep bootloader format and copies the file to the TFTP
+server's network wide location. The MVME2700 is configured to request
+``rtems.img`` from this location. The command ``pw-ctl`` is a command
+to control the power to the board.
