Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

  matherp said  The H/W watchdog will work in ALL circumstances. The test CSub did not disable interrupts so the S/W watchdog still worked. To test the H/W watchdog the CSUB needs to disable all interrupts. I can't think of a simple way of doing this from a CSub because you need to link the RP2040 sdk to get the register definition but I can guarantee the H/W watchdog WILL WORK in all circumstances


That was enough of a reply to convince me that if I use the HW watchdog in the 2040 chip, and NOT the software one, this SHOULD get me around the issue.

I still have no idea WHY the PM is crashing this badly, and it is only ONE unit out of fifty or so, all with the same code.  YES - have tried swapping out for a different PM module, but the same thing happens.

It's extremely odd.....    

However, if I just use the 2040's hardware watchdog as a work-around, that will settle things down till I can work out what the hell is going on.

Smoke makes things work. When the smoke gets out, it stops!
