Asset Tracker Program hangs before main on Thingy91

Question

Hi, 
 
 We are having trouble getting the Thingy91 firmware running as is. We have achieved this in the past but I had made too many modifications and I decided to scrap it and start over. But I didn't realise that I could've just reused the cmake file so I uninstalled and reinstalled the SDK. 
 We are trying to run the Asset Tracker project from the 1.3.0 toolchain. 
 So what happens is that when I build and debug instead of going to main() it stops here:

Then when it runs it hangs here: 
 
 I have tried to modify it to change the floating point configuration but I changed it back. I didn't try running it before the modifications

So, I figured out the problem. when I added an extra source file to the cmake file (that's how I add extra files, correct?) it was deleting the main.c file and this was because I neglected to add a proper CMakeLists.txt file to the directory. So now it works but I have 2 questions. 
 
 First we think that perhaps running from the code has a different sampling frequency from the other version he ran (out of the box). IS this possible? 
 When he was collecting data he was able to obtain the air_quality value but for me that code is absent. Is it possible to obtain this segment or get help on how to fix it? env_sensors.c int env_sensors_get_air_quality(env_sensor_data_t *sensor_data) { return -1; } this code is called from env_data_send(void) in main.c

Please go through the following steps:

Download https://www.bosch-sensortec.com/media/boschsensortec/downloads/bsec/bsec_1-4-7-4_generic_release.zip
Click on this:

Extract it the BSEC library and put it into C:\Users\<username>\ncs\v1.3.1\nrf\ext
- Make sure to not double the folders like this: C:\Users\<username>\ncs\v1.3.1\nrf\ext\bsec_1-4-7-4_generic_release\BSEC_1.4.7.4_Generic_Release, which may happen after you extract it
Then modified C:\Users\<username>\ncs\v1.3.1\nrf\applications\asset_tracker\prj_thingy91_nrf9160ns.conf accordingly:

-CONFIG_BME680=y
-CONFIG_USE_BME680_BSEC=n
+CONFIG_BME680=n
+CONFIG_USE_BME680_BSEC=y

Remove the folder in C:\Users\<username>\ncs\v1.3.1\nrf\applications\asset_tracker\build_thingy91_nrf9160ns if present
Open SES from the Toolchain Manager and choose the followin settings:

First time I run this I got a "Did not finish cmake", however I did it again with the same settings as above and it worked. I'll look into why this is.

Open C:\Users\<username>\ncs\v1.3.1\nrf\applications\asset_tracker\build_thingy91_nrf9160ns\zephyr\.config and make sure CONFIG_BME680 and CONFIG_USE_BME680_BSEC are set correctly. And that CONFIG_BOSCH_BSEC_LIBRARY_PATH points to the correct path
Next build the project:

That worked for me.

Best regards,

Simon

Thanks. It seems that for some reason it must've not registered the folder. But I just redid the last steps that I did and now it compiles the config file without any issues. So now it's working and I get the air_quality 
 It seems that the deciding factor was probably changing 1.4.8.0 to 1.4.7.4 and perhaps performing a restart of my system.
