Overview 
This is the Linux BSP (Board Support Package) for the NXP i.MX RT1050 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 RT1050 microcontroller using the NXP i.MX RT1050 EVKB board as a hardware platform.
