I have an issue with PMIC. It seems that Op-tee won't start och activate the PMIC. Do you know why? Any suggestion? The error is 0xffff0008 = TEE_ERROR_ITEM_NOT_FOUND.

Notice that I have copied the DT from DK board.

Hi @Olivier GALLIEN 

Here is the answer: The problem was that the interrupt was not enabled for PMIC inside the DT!

Once the interrupt GPIO was correct, then the error disapear.

Hi @DMårt ,

If you are working on customer HW closed to DK using DT related to DK I invite you to cross check with your hardware if any little difference may explain issue you are facing
