nRF52810 project on PCA20032 only starts with debugger.

We have migrated a project from nRF52832 to nRF52810.

We are using IAR EWARM.

The target hardware is the PCA20032 with the nRF52810.

The code runs fine on the PCA10040 DK target processor  (the nRF52832).

It also runs fine on the PCA20032 when started from the debugger, but when we start without debugger the red LED is flashing and the application is not started.

We have tried out suggestions from IAR: https://www.iar.com/support/tech-notes/debugger/application-does-not-run-stand-alone/ - including stuff found in similar threads here.

The softdevice used is S132_nrf52_3.0.0.

We have done a complete erase of the nRF52810.

There are no DCDC components on the PCA20032 as far as I know. Can you check if you enable DCDC in your code? If you do, it will only work in debug mode, since debug mode forces the LDO regulator on.

Spot on! Thank you :-)
