## Updating Firmware

First put enable `fwupd`

```nix
services.fwupd.enable = true;
```

Then run

```sh
 $ fwupdmgr update
```

## Suspend/wake workaround

As of firmware v03.03, a bug in the EC causes the system to wake if AC is connected _despite_ the lid being closed. A workaround has been [upstreamed](https://github.com/torvalds/linux/commit/a55bdad5dfd1efd4ed9ffe518897a21ca8e4e193) in Linux v6.7. For older kernels, the following works around this, with the trade-off that keyboard presses also no longer wake the system.

```nix
{
  hardware.framework.amd-7040.preventWakeOnAC = true;
}
```

See [Framework AMD Ryzen 7040 Series lid wakeup behavior feedback](https://community.frame.work/t/tracking-framework-amd-ryzen-7040-series-lid-wakeup-behavior-feedback/39128/45).

## Getting the fingerprint sensor to work

The firmware on the fingerprint sensor needs a downgrade to make it work on Linux.
The process is documented [here](https://knowledgebase.frame.work/en_us/updating-fingerprint-reader-firmware-on-linux-for-13th-gen-and-amd-ryzen-7040-series-laptops-HJrvxv_za).

However on recent NixOS versions also fwupd can no longer update the firmware.
Using the following snippet allows to temporarly downgrade fwupd to an old-enough version:

```nix
{
  services.fwupd.enable = true;
  # we need fwupd 1.9.7 to downgrade the fingerprint sensor firmware
  services.fwupd.package = (import (builtins.fetchTarball {
    url = "https://github.com/NixOS/nixpkgs/archive/bb2009ca185d97813e75736c2b8d1d8bb81bde05.tar.gz";
    sha256 = "sha256:003qcrsq5g5lggfrpq31gcvj82lb065xvr7bpfa8ddsw8x4dnysk";
  }) {
    inherit (pkgs) system;
  }).fwupd;
}
```

Afterwards the downgraded driver can be downloaded and installed like this:

```
wget https://github.com/FrameworkComputer/linux-docs/raw/main/goodix-moc-609c-v01000330.cab
sudo fwupdtool install --allow-reinstall --allow-older goodix-moc-609c-v01000330.cab

The error message above is harmless. After a reboot, I was able to enroll my fingerprint like this:

```
sudo fprintd-enroll $USER
```
