You can cycle power or press the reset button again to see that this code also persists in non volatile FLASH
memory.

Now, lets reinvoke the original program that was runnign prior to IAP download. Using PSDload, press
the User defined button
. A dialog will pop as below.
Figure 14 Application Specific Command, PSDload (User Defined)
In the window type RET in upper case and press OK. Observe the display on the eval board now shows
the PSDload Test banner on the upper line. This display indicates that the original CSBOOT resident
code is running again. You can do some other functions from PSDload like Write to Display to further
verify the original program is again active. For an explanation of the details that allow this to occur, see
Using DK900 as a Development Platform later in this manual.
j)
This concludes the IAP demonstration. These activities illustrate how a new code bundle can be
downloaded over the serial channel and invoked remotely from PSDload with a serial command. Also,
how another serial command can be used to return to the original code, pre IAP code. Good job!
