0.7.0-15.alpha software version

When using the 0.7.0-15.alpha firmware release. What is the best application side code to go with it. Should still tag v0.3 be used of: zephyr, nrfconnect and nrfxlib?

Especially with respect to the GPS this would be crucial - since there has only been the gps-sim.c code to take of the gps until now....what flags should be used for correct gps operation with0.7.0-15.alpha?

At this moment it is really not a big difference between the two, both are prone to bugs at the moment. I would keep master until we have v0.4.0 (non-rc) by the end of May.

Difference from v0.3 I do see though is S vs NS - what is the recommendation here? The new SPM does not seem to work very well with NS... Would be great with a pointer to an actual list of operations to make atleast a certain version of the code operational in SES 4.16....

In v0.3 SPM was previously named Secure Boot, this is now SPM. As the nRF9160 is running Cortex M33, it includes TrustZone which enables secure and non-secure domains. That is the reason for why we have divided the board into PCA10090s and PCA10090ns.

Updating your SDK with West will ensure the latest tag v0.4.0-rc2, and when building both SPM and <sample-project> will be merged into one hex. More information here and here. Be aware that the current version of SES 4.16 does not support the merged hex, but we have a workaround here.

There have also been issues with v0.3 and the newest modem FW, another reason to move away from the old version.

Hope this answers your question regarding the SPM. Let me know if anything is unclear.

Kind regards,
Øyvind
