Bill,

Just been having a look at your routines as I need to do some IAP now 
myself.
I have a few questions to you/the group if you don't mind:

1/ I notice you expect CMD_SUCCESS, never BUSY back from calling iap. 
This implies to me the iap routines always execute to completion before 
returning (this conficts with another posting to this group which showed 
a for(;;) loop waiting for non-BUSY return). Confused !

2/ If the iap routines don't return till all is done, what happens to 
the watchdog ? The watchdog cannot be disabled once started, so do
a) the iap routines feed the watchdog internally (philips question) ?
b) we need to reboot with watchdog disabled in order to do IAP ?

3/ I notice you prepare all sectors for write every interation of your 
writing loop. Is this just for easier coding ?

4/ In what cases would memmap be anything other than user code in 
practice ? (I notice you save and restore).

Bruce
