Actually，I have met the same problem, and the error log is same as above.
When debugging, i found a strange problem:
According to the error log, the "default:" statement of a "switch()" is
executed, and output the error log.
So i added two "printf()" before "switch()" to have a look why the two value
does not match, but strange things happen, auto boot successful this time,
and the two values are the same.
I don't know why...
