MBedderMake sure you have configured all unused pins as outputs. The pins which were left floating do readily grab the EMI which can easily cause resets and other unwanted effects especially on the...

OK. I did all the mentioned advice and added some of my own. I had 6 devices under test. Unfortunately 3 of them had the error again. They were all started at the same time, but the error of all three...

Ok, I just succeed to run the code with no errors for more than 24hours now. I disabled all the interrupts, and handled the interrupt routines in the main loop. Since this device is much more faster...

"Nope, not changing the PSV. But not sure if compiler does it behind the scenes." Only is you are accessing PSV data like a const table.

So, after some more days testing concurrent with an RealICE, we found out that every time the crash happens, the trace call leads us to a random mainloop/background function executing an return in...

Hi,As you have a real-Ice I suggest you set a data breakpoint on a write of a specific value in RAM.Maybe you can try to set a breakpoint when the word 0xFA52 gets written into the memory 28D6.If I...

You probably already know this, but - Be especially aware of non atomic operations in shared registers (such as interrupt flag registers and ports/lats). If the operation isn't atomic, and interrupted...
