Gpio-manager missing

Help
1

Hello,
I’m running NixOS on SBC with some GPIO pins exposed to tinkering (Radxa Rock 5B) and I would like to utilize them for my project.

I have libgpiod installed along with gpio-utils through configuration.nix file. On official documentation here I found out that there should be gpioctl command available but I can see only these:

gpiodetect      gpio-hammer     gpionotify
gpio-event-mon  gpioinfo        gpioset
gpioget         gpiomon         gpio-watch

searching for additional packages did not give me any straight forward answer as well as nix issues.

Am I missing something or are those tools not available at the moment?

Some information about my system:

  • Radxa Rock 5B 16GB
  • Bootloader: EDK2 in DeviceTree mode
  • NixOS 25.05
  • kernel 6.15: Linux Rock5B 6.15.0 #1-NixOS SMP Sun May 25 23:09:23 UTC 2025 aarch64 GNU/Linux

hardware-configuration.nix:

# Do not modify this file!  It was generated by ‘nixos-generate-config’
# and may be overwritten by future invocations.  Please make changes
# to /etc/nixos/configuration.nix instead.
{ config, lib, pkgs, modulesPath, ... }:

{
  imports =
    [ (modulesPath + "/installer/scan/not-detected.nix")
    ];

  boot.initrd.availableKernelModules = [ "nvme" "usb_storage" "usbhid" ];
  boot.initrd.kernelModules = [ ];
  boot.kernelModules = [ ];
  boot.extraModulePackages = [ ];

  fileSystems."/" =
    { device = "/dev/disk/by-label/NIXROOT";
      fsType = "ext4";
    };

  fileSystems."/boot" =
    { device = "/dev/disk/by-label/NIXBOOT";
      fsType = "vfat";
      options = [ "fmask=0022" "dmask=0022" ];
    };

  swapDevices = [ ];

  # Enables DHCP on each ethernet and wireless interface. In case of scripted networking
  # (the default) this is the recommended approach. When using systemd-networkd it's
  # still possible to use this option, but it's recommended to use it in conjunction
  # with explicit per-interface declarations with `networking.interfaces.<interface>.useDHCP`.
  networking.useDHCP = lib.mkDefault true;
  # networking.interfaces.enP4p65s0.useDHCP = lib.mkDefault true;

  nixpkgs.hostPlatform = lib.mkDefault "aarch64-linux";
}

And configuration.nix:

  imports =
    [ # Include the results of the hardware scan.
      ./hardware-configuration.nix
    ];

  # Use the systemd-boot EFI boot loader.
  boot.loader.systemd-boot.enable = true;
  boot.loader.efi.canTouchEfiVariables = true;

  # Use latest kernel.
  boot.kernelPackages = pkgs.linuxPackages_latest;

  # GPU enable
  hardware.graphics = {
    enable = true;
  };

If any additional information are needed, please let me know. I am completely new to Nix so I don’t know if I provided enough/correct info.

Thank you in advance :slight_smile:
