No - the "fis load" command will set 'entry_address' to 'NO_MEMORY' if
there is a CRC error.  This code should catch that and cause the 'exec'
command to fail.  Of course, it can only do this if you do not specify
an entry point address.

Exactly what does it do?  Perhaps you could print the value of 'entry'
when it gets to this point.
