nrf connect sdk optimization lowest levels

[Simon Feutrier]

Hello,

When I change the optimization for a project to NO_OPTIMIZATIONS or DEBUG_OPTIMIZATIONS in the configuration (prj.conf), I always go in the hard fault handler (with NO_OPTIMIZATIONS, it fails direclty).

I can reproduce this with the sample "ncs\v1.8.0\zephyr\samples\bluetooth\peripheral", without any modification except the optimization.

I use nrf connect SDK 1.8.0 and SES V5.68 with nrf5340.

Can you help me on that ?

Regards.

Hello SwRa ,

Which logs do you mean ? Are you talking about the Call stack ?

The peripheral sample only crashes when use no optimization ; it works with debug optimization

In my code, with debug optimization it initializes correctly. But on a button trigger I try to fetch value from a sensor and it  crashes. Of course it works when optimization is the default one.

Hi Simon,

Providing any log that shows the error or the logs from the crash would be helpful for us to check. Also, are you building with "_ns" extension ?

Best Regards,

Well, I have changed my workflow and I have no more crash in debug optimization.

I will open a new ticket next time I have a new issue of this type.

Thank you for your time.

Best regards,

Simon
