Can you add a printk or similar to the if statement, and see if it gets printed every time?

If the assert isn't being printed, there might be some kind of race condition that triggers it occasionally.

You can zip your whole working directory and attach it, and I can try to reproduce what you are seeing and debug it for you.

Hello Heidi,

When I use stepwise debugging and step over an __assert() expression, I get the message on my serial monitor.

But if I let the application run and I still have the debug context open in SEGGER Embedded Studio, I don't get the assert message.

If I run the application without any debugging, I get the assert message, but still not every single time.

It would be nice, if the assert mechanism would provide the message consistently every time an assertion triggers.

Are there any known issues with the Zephyr assert mechanism?

Hi!

Are you doing stepwise debugging? That can change the timing of the things happening in the application.

Best regards,

Heidi
