Overview

This is the Linux BSP (Board Support Package) for the NXP i.MX RT1170 EVK/EVKB board.

The BSP provides a software development environment for evaluation and development of Linux (uClinux) on the Cortex-M7 processor core of the i.MX RT1170 microcontroller using the NXP i.MX RT1170 EVK / NXP i.MX RT1170 EVKB board as a hardware platform.
