Read MC9s12xdg128 2M42E tonight. Very smooth easy read and verify flash and eeprom. Security bit is at 1ff0f and is 0xfe unsecured.
I erased the eeprom then erased the flash thinking of course the software would not be written so as to secure the chip and will write security byte 0xfe....
No chip is now locked!!! Why do this?
How do I recover the chip now please?
Thank you

Use the option 2-MCU,MOTOROLA-MC9S12,MC9S12XDG128_SUCURED to write directly(and connect the chip by this options's wire connection)

This is how I read it and erased it and how it will not read anymore.

Edit:
Do you mean, although I can no longer read it I may be able to write the saved dumps back using this method, the method I read it with initially?
Thank you for your replies.

I have just tried. No read, no write. The chip will return correct ID c102 but no read or write.
Maybe this could be looked at for future versions? I cant see anybody wanting to erase and lock the chip like this, at least not without warning maybe?
