i.MX 8M Mini Migration Guide: Migrating from i.MX 8M to i.MX 8M Mini
●Purpose:
■This application note introduces the i.MX 8M Mini architecture by highlighting the differences from the i.MX 8M series processor upon which it is based. This document is a migration guide for developers that migrate from the i.MX 8M to the i.MX 8M Mini processor.
●Scope:
■The i.MX 8M Mini architecture introduces new features which are different from the i.MX 8M. The i.MX 8M Mini also removes some features from i.MX 8M. The key differences include:
▲Reduced the package size from 17×17 mm, 0.65 mm pitch to 14×14 mm, 0.5 mm pitch.
▲Optimized power consumption.
▲Increased Arm® Cortex®-A53 core platform frequency
▲Increased Arm® Cortex®-M4 target frequency
▲Removed display controller subsystem (DCSS), so HDR and Dolby vision is not supported.
▲GPU 3D changed from GC7000 lite to GCNanoUltra, Single Shader support, OpenCL/Open Vision/Vulkan is not natively supported.
▲Added 2D engine GC320, can use 2D for Color Space Conversion (CSC) and buffer transfers.
▲Added one video encoder, the decoder performance is 1080p60.
▲Added PDM audio input support.
▲Supported 192 kHz audio on SPDIF interface.
▲Increased lanes on SAI-2/3 from 1TX+1RX to 2TX+2RX lanes, with support for 768 kHz audio.
▲Changed 2×USB3.0 to 2 ×USB2.0.
▲Removed second PCIE and second MIPI CSI, do not affect the software.
▲Removed HDMI interface.
▲Added third SD/eMMC interface.
▲Added third SDMA for audio interface.
■Due to a close alignment to the i.MX 8M design, this document is structured as a summary of changes to the i.MX 8M Mini features. It provides references to modules that are reused or modified on the i.MX 8M Mini.
●Audience:
■This document is intended for system integrators and software developers migrating from the platforms based on the i.MX 8M.
