How can I safe a latched condition and have it available on my next boot.

It will be a memory of a failure.

Hi Bgtwuk
You can make a parameter that your program writes into.
And when system boots up, the program reads the parameter.
It is not difficult, I believe there are examples somewhere :)

I have done this to log machine overload and other useful info.
If you want more details you could make a timestamp value and number of failures.

Did you make it work, Bgtwuk?

Might also be a good idea to prevent frequent status logs, the controller memory is just not made for it. According to the documentation, it will wear out the memory after a few million logs or there about. Display memory is different so if you have a display that is where I would store logs.
