At first thank you Tschako!!
Oh bad News but that's what i tought.
If I manage to change the flash memory, how can I flash the Chip?
Can I make a complete Backup from flash memory, from a working Unit?
Than only flash the new chip with the Backup?
I don't know how I can flash the IPL Image.
Because without the IPL, I think I have no communication between the Unit and the Terminal!
Need I a special cable or software to connect with the Unit?
And that the right flash memory ( Spansion S29GL512N )?
sorry for the many questions, but i'm new in this area.
It's a new Hobby
