Flash emulation workaround

Hi

I'm using the 72F264 flash memory as eeprom in my application, problem is the DVP3 tells me it can't emulate the flash control register, in fact i get a stop error every time it's accessed.

This causes a problem trying to run the application in real time!

Does any know a work around for this?, i can put a define in to block accesses to the fcsr when emulating, but will the dvp3 then allow me to write to the flash memory and read back the data?

Thanks

No, it is not possible with DVP3 or emulator as it does not have the true flash.

Moderator is right, Flash is not emulated.

The only work around on DVP3 is to avoid read/write to FCSR and modify the mapping of program area as RAM instead ROM.

That will alows you write to the program memory and read back the data.

But be carefful, this modification will remove the protection of program memory.
