Max10 Flash Page Erase Failure

Per the user guide, section 4.2.5, the only way a page erase can fail is for a wrong address

 

"The flash IP core sets the erase successful field in the status register to 1b'0
(failed) if you send an illegal address. "

 

I have seen it fail, within 1us, and then successful with the exact same address.  What would cause occasional page erase fails.    A simple retry corrects the problem, so the exact same series of commands (and timings) cause it to sometimes fail.  We have already checked the power supplies.

You can try to add some delay before executing a command.
