Yes and no.
MCUXpresso can handle the Cortex-M4 processors which are in some of our i.MX devices, for these we offer platform support. At the moment this is the case for the Cortex-M4 inside the i.MX 8M. But others will follow.
This includes compiler and debugger support.
MCUXpresso is not able to deal with the Cortex-A processors inside the i.MX devices.
