TZ_NONSECURE_FUNC_PTR_CREATE SPM error with v1.0.0 for nRF9160

[MJD093]

Hello,

I have seen today that the new releases of the v1.0.0 SDK and v1.0.0 modem firmware were release for the nRF9160 DK. I have been able to update the modem firmware but I'm coming across an error with the SDK.

Every time I try to build I get an error from the SPM code about about TZ_NONSECURE_FUNC_PTR_CREATE. This error occurs no matter what the code I try to build, be that my own custom application, SPM itself or any of the example programs.

I had orginally updated my ncs folder with my custom additions but this occurred after I updated. I then renamed that ncs_backup and did a fresh install in a new ncs folder of the repos using the instructions in 'Getting Started' and the same issue occurs.

I have managed to build 1.0.0 by updating the branch and west and pip3 with latest requirements on Ubuntu. While this is not particularly helpful for your issue, it does mean it is buildable.  Attaching a built asset tracker firmware if you wish to test things with it if that helps. I face the following issue with it: https://devzone.nordicsemi.com/f/nordic-q-a/49328/nrf91-sdk-v1-0-0-at-command-baud-problem  build_nrf9160_pca10090ns-v1_0_0-merged.hex

[MJD093]

Yes I did this as well, fresh install of the repos, west update, git checkout and pip3 the 3 required python module scripts as in the 'Getting Started Assistant' but it still didn't work :/

Do you happen to have at_client's merged.hex? The asset_tracker won't work on my DK as I have no NB-IoT network in my current location (and the NB-IoT network I do have can't use the Dynamic Amazon IP address the asset_tracker needs for nRF Cloud ) but the at_client would allow me to test the modem firmware update in the mean time.

EDIT:

Oh dear, I get an immediate hardware fault with that hex file, and that's during the boot up information, not the main application. :/

No idea about hte error, but that may as well be the error I am getting but not seeing due to some baudrate problem. Give this at client fw a go and please let me knowat_client-build_nrf9160_pca10090ns-V1_0_0-merged.hex if it works for you.

EDIT: The above firmware is known not to work, see below for answers!

I had to change toolchain versions when I updated to v1.0.0.  I was getting the same error when using "gcc-arm-none-eabi-8-2018-q4-major" as the toolchain.  The "nRF Connect v3.0.0 -Getting Started Assistant" app was updated at some point, and the toolchain it says to install is now "gcc-arm-none-eabi-7-2018-q2-update".  When I switched to that it started working.  Though all of this is on Linux, the toolchain world may be different for mac.

I think Arm added handling for a new intrinsic related to the TrustZone stuff.

I have the same error... ISR ( slomusti ) this is with your hex file
