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.

Hi,

 

There seems to be two issues that might be related in this thread:

1. TrustZone defines not working with GCC 6 or GCC 8. We are aware of this, and it is reported internally, but for now; please use GCC 7 (2018-Q2). GCC 8 has had other issues, like linking errors on the windows platform, so it has been ruled out for now.

2. nrfjprog v10.1.1 has an issue where it does not properly do a sectorerase on nRF9160 in certain corners (which ninja/west calls in the background). This should be fixed with the latest version v10.2.1, available for download here: https://www.nordicsemi.com/?sc_itemid=%7B56868165-9553-444D-AA57-15BDE1BF6B49%7D

 

Could you see if these two items resolve the issues seen in this thread?

 

Kind regards,

Håkon

[MJD093]

Hi again Håkon,

Thanks for the information.

1. This seems to have solved the issue. Funnily enough, I actually had that version of the GCC compiler on my mac in case it was ever needed for this occurance.

2. I was running the 10.2.1 version of nrfjprog as I updated everything yesterday to get the modem firmware onto the DK.

I can now report that the FW build and flashes onto the device correctly for me now with the GCC compiler change.

One question I have Håkon that isn't related to this but has us a little stumped.

We have built up our first prototype for the nRF9160 but are not able to communicate to it. Both JLink and the nRF Programmer can't seem to detect the core.

We have run a multi-meter around the board and everything seems to be getting supplied the power it needs as per the OPS guidleines. We have noticed that the NRESET line is 0V. From the OPS we know that there is an internal pull up resistor to VDD on the NRESET pin and from metering the DK we know that there is 2V on the reset button for the pca10090. Is the NRESET pin supplied with voltage from the moment the VDD line is supplied or does the NRESET line only get supplied Voltage after the core have been initialised with FW. Just trying to figure out if we have an issue with VDD being supplied with power as we can't see under the SiP.

[Håkon Alseth]

Hi,

 

Sorry to hear that your prototype is refusing to communicate!

The nRESET signal will be kept low until the Power-on-reset (POR) logic internally releases it. This is normally some milliseconds after it has reached a valid voltage threshold, depending on the rise-time of your supply.

Does the PCB draw any current from the battery?

Have you checked the voltage level on the ENABLE pin?

 

Kind regards,

Håkon

[MJD093]

Thanks for that information, so there isn't anything weird going on with NRESET, it must be something else on the board.

We are supplying VDD with a regulated 3V3 battery supply that is within the tolerances of the VDD line.  ( we would like to keep 3V3 if possible as this would allow any device to remain active for longer before the battery supply voltage dips below 3.3V)

Our prototype PCB draws a small current i.e. a few milliamps (10mA), and both the NRESET and ENABLE lines were my first thought as possible areas of concern. From our examination, the LDO is outputting 3.31V (so pretty good LDO) which the ENABLE Pin is receiving. The NRESET was 0V so I thought something was wrong there but if the internal logic isn't getting initialised this would be 0V.

May I ask you to post at client compiled binary please as well for a test. I am trying to determine if compilation is an error on my end or something else.

[MJD093]

Sure thing slomusti

7888.merged.hex

EDIT: not sure why the uploaded file is getting a pre-fixed number, be sure to remove the "7888." from the filename. Apart from that, I downloaded it and flashed it from this post and it works on my DK. Hope it helps :)

[Håkon Alseth]

If the enable pin is getting 3.3V, that is good. nRESET being at 0V is not so good. Have you checked if it is shorted to GND? Disconnect the battery, and check with a multimeter.

nRESET should go up towards VDD_IO a few ms after the chip is enabled.

[MJD093]

Yes, my colleague has removed the reset button (in case it was a faulty button or there was an layout errors with the button SMT pads) and multi-metered around the nRESET line and there doesn't seem to be any shorts to GND on that line. No short to ground and no short to any pins around the nRESET pin.

[Håkon Alseth]

I think we'll need to check your design/schematic. Could you create a new private case? (I guess you do not want to share your design with the rest of the world)

Link to this case, so that the history is kept

It might be handled by one of my colleagues, as hardware isn't my strongest feature.

 

Kind regards,

Håkon

[slomusti]

Thank you. Unfortunately this does not resolve the issue, I get the error below:

Note that this is being tested on our custom board, however should be no different to DK. I have the latest NRF connect 3.0.0, manually updated nrfjprog to the latest version and installed the latest modem FW 1.0.0.

Håkon Alseth any thoughts what else to try?

Thank you, HW has been already reviewed by your colleagues via email and passed without comments.  We have multiple boards running well with with old modem firmware and a few with an unknown problem of not being able to connect, but at client is running well on all.

The new modem FW is running well on the DK as well as the at client example. Thus the above error is somewhat HW related, not sure how.
