Nope, i cannot tell you why this is happening, you will have to debug
it yourself.
Do you have CYGPKG_INFRA_DEBUG enable?
Put some breakpoints in flashiodev_getconfig at the two locations it
returns EINVAL while erasing. See if they get hit. I would also add
some code to flash_erase() to detect erases to areas you think it
should not be erasing.
