I’m investigating an intermittent behavior I have seen on a board stack in front of me - wherein execution may stop in the BootROM code, with an error message of “Start clear bit timeout”. See the attached image. This appears to occur randomly, and perhaps more likely under some setup conditions I don’t yet understand.  
Question for someone familiar with the BootROM code: What is this error message saying?
