NXP i.MX8 SOC family support

1. Supported devices

• i.MX8QuadMax Multisensory Enablement Kit (imx8qm-mek) - device-specific U-boot and Linux kernel, nixos configuration example.
• i.MX8QuadXPlus Multisensory Enablement Kit (imx8qxp-mek) - device-specific U-Boot and Linux kernel.

2. How to use

2.1 For imx8qm-mek

Currently this NXP overlay is used for generating EFI-bootable NixOS images. I recommend to use Tow-Boot as a bootloader, but U-Boot from this overlay can also be used. U-Boot was tested separately from NixOS.

Code snippet example that enables imx8qm configuration:

{ nixos-hardware, }: {
  system = "aarch64-linux";
  modules = [
    nixos-hardware.nixosModules.imx8qm-mek
  ];
}

2.2 For imx8mq-evk/imx8mp-evk

This NXP overlay is used for generating sdimage. Current configuration uses uboot as a bootloader. It provides an options to use optee-os which is currently disabled. It can be enabled using enable-tee boolean argument avalable in imx8m<q/p>-boot.nix, which is false by default.

Code snippet example that enables 'imx8mp-evk/emx8mq-evk' configuration:

{ nixos-hardware, }: {
  system = "aarch64-linux";
  modules = [
    nixos-hardware.nixosModules.imx8mp-evk  #For imx8mp-evk
    #nixos-hardware.nixosModules.imx8mq-evk  #For imx8mq-evk
  ];
}
