Release Notes 3.0.0 Print




This is the Linux BSP (Board Support Package) for the NXP i.MX RT1024 EVK 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 RT1024 microcontroller using the NXP i.MX RT1024 EVK board as a hardware platform.
