Trouble w Processor Expert FLASH_LDD Component

Using KDS v 3.2.0

Processor is KE02Z32VLD2.

Debugging with P&E Multilink

I let PE set the clock frequency to 1MHz.

I've set up four user memory areas in upper memory:

My intent is to store operational data in these areas for safe-keeping upon power-down.

I thought I would start with erasing one block of this memory. Following the example in the "Help on this component" I have the following:

You can see the breakpoints above. I reach the first one just fine. But when I continue from there, I end up here:

. . . as if I stumbled on a Reset or something.

I have tried "Safe launch and wait" - with and without "Interruptable wait loop" checked. And I have tried without "Safe launch and wait".

Flash protection is set to "No protection"

There ARE timer interrupts running while I'm attempting this. Adding __DI(); before calling the FLASH_LDD methods did not seem to help.

Any ideas?

Thanks.

Thanks for the quick reply Alice.

Here is the screen shot:

I will send the zipped project as a private message.

I've been looking around some more and I've found . . .

This discussion:

Why does KM14 reset when erasing flash?

And this seems to work:

I thought I understood that I could still read FLASH while a different block is being erased, but I guess not(?).

Any suggestions for improvement would be appreciated.

Alice,

Thanks for your help.

Just so I'm clear . . you cannot read from FLASH memory while it is being erased or programmed. Correct?

How about the EEPROM? Does that have the same restrictions?

Thanks.
