This is the Linux BSP (Board Support Package) for the NXP i.MX RT1170 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 RT1170 microcontroller using the NXP i.MX RT1170 EVK board as a hardware platform.

Supported Features

The following list summarizes the features and capabilities of this release of the NXP i.MX RT1170 EVK BSP:

  • Linux:
    • Kernel v.4.5;
    • Serial Linux console;
    • Ethernet device driver and Linux TCP/IP networking (ping, NFS, Telnet, FTP, NTPD, etc);
    • busybox v1.24.2;
    • POSIX pthreads;
    • Hardened exception handling; an exception triggered by a process affects only the offending process;
