In the process I've had more than one board ending up booting (at 78k) with a parameter area issue.

In an ESP12 that is typically right at the top of the 4 Meg. Using various tools I've tried to wipe 4 * 1 meg and always hit a problem wiping the top 1 meg - or part of it.

It just occurred to me that presumably there is a write protect at that top system parameter area stopping me doing a clean wipe.

I tried using the ERASE function on the ESPTOOL and while that say ok I still have the problem.

Is there a special flag I need to use with ESPTOOL to include wiping that (possibly) write protected system parameter area to get an absolutely clean 4MB FLASH??

I have one board I simply cannot now get to work properly and I suspect this has something to do with it?

Pete.
