Hi Len, That certainly used to be a problem with older windowed EPROMS. I know that it's possible for FLASH cells to flip from cosmic radiation, and cells can go bad from repeated writing, but the bootroms we employ are loaded into write protected memory and are usually never re-written.
There is typically no way to re-flash the bootrom without a suitable programmer (hardware). In-field write protection of the bootrom is critical for a robustness.
