Hi, i am development a project with imx287 and i am using the SCH EVK with as reference, but I need to use the SSP0 connected to a device with 3V3 voltage domain and the interface SSP2 connected to a device with 1V8 voltage domain.
I can do this only by software configuration by editing the "mx28evk_pins.c" or should I really put a shift voltage in SSP2 interface to change voltage of 3V3 to 1V8?
Thanks.

Hi Mario,
The IO on i.MX28 can support dual voltage, and you only need to configure it by software. It will set the IOMUX registers to set the IO to 1.8V.
