Hi @Maksh.1 ,

did you generate your DT using CubeMx ?

Could you elaborate on the 'unable to assign' ? It there any error messages ?

Please have a look to this post which highlight the need to use pinctrl_z:

Please also look at https://wiki.st.com/stm32mpu/wiki/How_to_assign_an_internal_peripheral_to_a_runtime_context

and ensure you have only and &spi1_m4 "okay" (i.e. keep &spi1 "disabled")
