I'm handling the customer return of our product. Usually it is pertaining single or double bit flipped. The most recent one is quite unusual, from the memory dump, the entire code is gone! I'm seeing the entire memory as "0xFF" only.
Is it likely that the flash decoder or the charge pump is damaged? Is there anyway (not by re-programming) to verify what type of failure on the chip? Do you provide memory forensic service? Thanks.
