Problem with MQTT_Simple

[craig.goldman]

I am having a problem running MQTT_Simple on my nRF9160 DK.

The COM Port shows the following:

***** BUS FAULT *****
  Precise data bus error
  BFAR Address: 0x4002a514
***** Hardware exception *****
Current thread ID = 0x20000324
Faulting instruction address = 0x6704
Fatal fault in essential thread! Spinning...

I have recently updated SES, but the code still produces the bus fault.

Case ID: 226428 seems to be similar, but the discussion involves several "experiments" only some of which were productive.

So, could someone explicitly lists the steps needed to get this example working.  I wish to use it as the basis for a new product that sends data to the cloud.

Thank you,

I appreciate your help, but I am not making much progress.

I switched the board to nrf9160_pca10090ns.
I cleared out the build directory so I get a clean build.

The "Open nRF Connect SDK Project" fails.

The end of the log shows the following....

Zephyr version: 1.14.99

Any thoughts?

There are three pca100090ns files:

nrf9160_pca10090ns.dts
nrf9160_pca10090ns.yaml
nrf9160_pca10090ns_defconfig

Is something else needed?

Hi Craig, 

In SES, can you please go to:
Tools --> Options --> nRF Connect

Make sure your Zephyr Base is pointing to: 
C:/Users/info/Dropbox/64Seconds/NCS/zephyr/

Let me know how that works for you.

Kind regards,
Øyvind

No listing.

File --> Open nRF Connect SDK Project looks like the following...

This fails.

After that when I do Tools --> Options, I get this....

Does this help?

[craig.goldman]

Forgot to mention, when I do File --> Open nRF Connect SDK Project using

Board Directory: C:/Users/info/Dropbox/64Seconds/NCS/zephyr/boards/arm/nrf9160_pca10090

(i.e without the "ns" on the end), the project will open.  It just will not build (as described earlier in this thread.)

There seems to be an issue with the installation of Segger Embedded Studio. This is what it should look like:
