"Hard Fault" out of the blue

Post by mcc » Sat Nov 10, 2018 9:29 am


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.

DM 42 - SN: 00373, Firmware v.:3.11. / 3.11. as compiled by SwissMicros
