FRDM board programming/erase limit - KE06Z

I am using a couple of FRDM-KE06Z for my team to use to load new software into some prototype units.

We’ve been doing this for a while, but now the board quit working, and always gives an error (green LED blinks).  I have duplicated the problem here by loading the same file repeatedly.

Eventually the board quits working, and there doesn’t seem to be any way to recover it.

I believe that the flash on the MCU has a 10k minimum erase/program cycle limit. 

Is there a limit that P&E built into the software so this kit cannot be used as a production programmer?  This is not our intention, but we have a large number of prototypes to deploy for a large field trial.  This is only needed during product development and field testing.

I would just like to know for my own information what the limit is when loading the same file over and over.

If we make software revisions, I would assume it would keep working as that’s typically how a dev board is used.

If there is a limit and I know what it is, that would be good to know.

Is there a low cost programming solution for low volume applications like this?

Any feedback or input is welcomed and appreciated!

Thanks again!
