Hello again, Nicolas!

I believe I have tracked down the issue. Some peripherals, like UART0 and SPIM0 cannot be active at the same time. Hence, I recommend that you use SPIM1. However, if you want to use SPIM0 you have to apply an overlay file to the project in order to disable UART0. I've attached the one I used to make it work: devzone.nordicsemi.com/.../0250.nrf5340pdk_5F00_nrf5340_5F00_cpuapp.txt

Place this file in your project directory, and change the type from ".txt" to ".overlay". Note that I've enabled UART1 with the same configuration as UART0 in order to get serial output.

Hope this works for you!

Best regards,
Carl Richard

Hello!

I'm not seeing the same behavior when testing here. Could you share your prj.conf, as well as your nRF5340 PDK version number?

Looking forward to help you with this!

Best regards,
Carl Richard
