1. Overview

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.

2. Supported Features

The following list summarizes the features and capabilities of this release of the NXP i.MX RT1050/RT1060 EVK BSP:

• Linux:

  • Kernel v.6.12.20;

4. Known Problems & Limitations

This section lists known problems and limitations of this release:

1. If the program being debugged is compiled with the -g flag, then the "gdbserver :1234 app" command produces the kernel warning.
   ID: RM 7561.
   Workaround: Do not pay attention on this kernel warning, continue debugging the application.
