"Hard Fault" out of the blue

Post by mcc »

Hi,

while programming my DM42 suddenly a
"Hard fault" was print onto the cleared screen, then "QSÜI checking" (something
like this...all this happens too fast)...and VOILA! RAM was cleared and the previous
status of the DM42 was loaded.

There was no USB connection.
There was no mechanical impact (beside me,
pressing the buttons while programming).
The battery was at 2.82V and the ambient temperature
was at normal room level.

I am ... buffled.

Cheers!

HI,

it hit me again...this time only "QSPI checking" was displayed, the RAM was cleared
and I had to recover the programs from flash.
As it happens I was playing with the short routine shown here:

Hello Meino,
I don't see any answers from other users or swissmicros to your problem report.
Did you contact swissmicros additionally direct (via PM or other mail)?
Did you get any answers, or did you find some solutions for your self?
greetings, Thomas
