Hello,

We're looking for a solution for using the DFlash section of memory that will perform eeprom emulation for us, rather than writing a specific driver for it. So far we've not found much other than an old reference to an XC2000 processor from infineon.

Is there a driver written for doing eeprom emulation on the Aurix, or is it expected that the customer implement their own eeprom emulation?

Cheers,

Are you planning on using AUTOSAR? There is a specific AUTOSAR driver called FEE (Flash EEPROM Emulation) that would serve your purpose. It is part of the basic MCAL driver package. You can find the specification at http://www.autosar.org.

At the moment we were not planning on using Autosar, we're writing our own system from scratch. I looked at the FEE driver specification and I think it would help us write our own eeprom emulator if that's what we have to do.

It is possible to use the MCAL FEE driver in a non-AUTOSAR environment. You can buy a license for FEE by itself.

Writing your own FEE driver is a significant investment. It's hard to tiptoe around the Erase Disturb limitation.
