Hi and thanks for the patience, is has been vacation time here in Norway

Could you trying using NCS 2.9? We don't recommend using upstream Zephyr

It would also be good if you can provide the overlay for the board and any error you are seeing.

Can you provide the SDK version you are using? It will also be helpful in you include the errors you are seeing and your prj.conf. Without any information it is not possible to recommend what you should try.

&i2c1 is the i2C number for nRF53DK
