Just to keep this up to date:

¹ The SoftDevice S132 v3.0.0 has limitations when running on nRF52840 and should only be used in the context of demonstration and experimenting with the new device.

² The S132 SoftDevice Specification v3.1 describes the S132 SoftDevice v3.0.0 running on the nRF52832 IC and is not fully applicable to the nRF52840 IC.

Finally! The nonexistant did the trick. Before when adding this the execution started at 0x212B0 ( my application init code ), but when adding the nonexistant to the entry pointsymbol it starts at 0x8E4 ( inside softdevice )...

After googling "nonexistant + rowley" I found some information that this is necessary to make sure execution starts in softdevice, and not my application, so fits with what I saw when running with/without nonexistant.

But anyways, thanks alot!

Ok. Seems to be working here. I didn't start totally from scratch though. I installed the nRF5 CPU Support Package Version 3.5. I'm not sure if you did that. I used the same memory settings as you did. In addition I changed the following things:

Add "nonexistant" in Entry PointSymbol.
Add STARTUP_FROM_RESET in Preprocessor Definitions.
Change Can Erase All to "No" in Target Loader Options.

According to this. I guess this also could be of help.

Not using any examples, writing from scratch, but everything else works just fine..But as soon as I make any functioncalls into softdevice it jumps right from SVC interrupt to hardfault. CPU hardfault, the softdevice error handler I defined and passed in the sd_softdevice_enable dies not get called..

Have you gotten any examples without SoftDevice to work?

Both S132 and S140 supports the nRF52840 device ( according to Nordic sites ). The S140 is designed for Bluetooth 5 support, which is not present in the S132 ( Only BLE )

Try the S140 SoftDevice which is designed for nRF52840.
