RA:The Trust Zone in RA6M5

Hello,

Thanks for reaching out Renesas Engineering Community!

A common issue would be the lack of stack that makes your code enter the Default Handler. Have you tried to increase the stack under BSP stack and make main stack size bigger as shown bellow?

Also check the document provided bellow with a list of the common exception for RA MCUs.

Hope this helps.

I tried that, but it didn't work out

Hello again,

We will need more details about your project in order to be able to replicate your issue.

Could you please share with me your project if you would like to take a look on it?

Thank you very much. I have found the cause of the problem. It is because there is a problem in the setting of IDAU that causes the above problem in the project.
