RE: nRF9160 stops on vector catch

Working with Nordic Connect SDK 0.4.0

It is possible to continue using Segger Studio with Nordic Connect SDK 0.4.0.

the first thing to do is erase your current board just so we are starting with a clean slate.

Open the SPM project

Then from the tool bar select Target>Connect J-Link

Then in the target menu select Erase All to erase everything on the nRF9160.

Now we will need to program the modem firmware.

The current version on the web site is mfwnrf91600729.alpha. unpack and program using the command prompt ( this is a one time operation).

nrf9160_mdm_dfu –update

once the modem firmware has been programed we are ready to program SPM (Secure Partition Manager). In Segger Studio navigate to main.c in the spm project now press the green arrow in the upper right corner of the editor paint to build and debug the program.

Once you run the program you will get an error

Preparing target for user application

Executing Reset script TargetInterface.resetAndStop()

Reset: Halt core after reset via DEMCR.VC_CORERESET.

Reset: Reset device via AIRCR.SYSRESETREQ.

Stopped by vector catch

in the output window this is fine since there is no program in the non secure partition yet.

Now in the file at_client/prj.conf add the line CONFIG_SPM=n.

your project config fill should now look like this

# General config

CONFIG_ASSERT=y

CONFIG_TEST_RANDOM_GENERATOR=y

CONFIG_SPM=n

# Network

CONFIG_NETWORKING=y

CONFIG_NET_SOCKETS=y

CONFIG_NET_SOCKETS_OFFLOAD=y

Thanks for the pointer.. it worked for me.

I was having the same problem with the asset tracker in v0.4.0 on the nrf9160 and used these instructions to get past the vector catch issue.

My question is this - How do I modify the the asset tracker project to program the correct region? (I was running into this on the asset tracker)

Second question is how do I get the debugger started if I can't get the project started correctly with the Build-> Debug and Run menu?
