Nrf5340 i2c not working in non secure

[SnaiderBG]

I am following this example https://github.com/crfosse/ncs_projects/tree/main/peripheral_zephyr , both secure and non secure and I am not being able of making the non secure version work with the nrf5340, ncs version 2.8.0.

The error that appears is:

[00:00:00.380,798] <err> os: ***** BUS FAULT *****
[00:00:00.380,798] <err> os: Precise data bus error

The secure version is working correctly.

Hi

That example is 4 years old and may not be supported in NCS 2.8. I would rather start by having a look here https://academy.nordicsemi.com/courses/nrf-connect-sdk-fundamentals/lessons/lesson-6-serial-com-i2c/

Hi runsiv , I am facing similar issue, I have gone through the suggested sdk course and using provided example only it works with cpuapp but not with cpuapp_ns, Please help using nrf5340dk with SDKv1.9.0
