Release Notes Print



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 EVK board as a hardware platform.

Supported Features

The following list summarizes the features and capabilities of this release of the NXP i.MX RT1050 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;
    • MPU user-level protection support;
    • Secure shell (ssh) and secure copy (scp);
    • SD Card partitioning;
    • Multi-port serial UART driver;
    • I2C bus driver;
    • USB Host and Device (gadget) device drivers for onboard USB Host and OTG interfaces;
    • LCD (frame-buffer) and touch screen support;
    • WiFi connectivity with security;
    • PPP-based TCP/IP connectivity over GSM/3G modems;
    • Bluetooth support using bluez;
    • GPIO device driver.
  • U-Boot firmware:
    • U-Boot v2017.09-rc1;
    • Target initialization from power-on / reset;
    • Runs from the SD Card and internal ITCM (no external memory required for standalone operation);
    • Serial console;
    • LCD splashscreen support;
    • Ethernet driver for loading images to the target;
    • Device driver for SD Card and self-upgrade capability;
    • Autoboot feature, allowing boot of OS images from the SD Card or other storage with no operator intervention;
    • Persistent environment in the SD Card for customization of target operation;
    • Sophisticated command interface for maintenance and development of the target.
  • Development tools:
    • Linux-hosted cross-development environment;
    • 4.7.4 GNU toolchain is used for development of U-Boot, Linux and user-space applications;
    • Cross GDB for debugging user-space applications;
    • mkimage tool used by the Linux kernel build process to create a bootable Linux image.
