1. Loader code in flash is erased.
The regions of flash memory which hold
the loader code are both erased. (There
are two redundant loaders in flash that
can be run).
This may occur in when
there are ESD
disturbances or in
electrically noisy
environments. If this error
persists it may be a
hardware issue.
