verify PFlash_Program()

[tafengchung]

How can i verify flash program?

I use this PFlash_Program() function to program s12xep100

But, I can't see any change in memory windows.

Hi tafeng,

when you launch debugger, click "Hotsync" button in P&E connection manager for each target connection.

The Hotsync button in the Connection Assistant allows the user to connect to an already running target. thus you can check the debugger memory window, if your flash is successful programmed.

Have a great day,
