+OpenOCD implements numerous ways to program the target flash, whether internal or external.
+Programming can be acheived by either using GDB @ref{Programming using GDB}, or using the cmds given in @ref{Flash Programming Commands}.
+
+@*To simplify using the flash cmds directly a jimtcl script is available that handles the programming and verify stage.
+OpenOCD will program/verify/reset the target and shutdown.
+
+The script is executed as follows and by default the following actions will be peformed.
+@enumerate
+@item 'init' is executed.
+@item 'reset init' is called to reset and halt the target, any 'reset init' scripts are executed.
+@item @code{flash write_image} is called to erase and write any flash using the filename given.
+@item @code{verify_image} is called if @option{verify} parameter is given.
+@item @code{reset run} is called if @option{reset} parameter is given.
