Caution: This page may contain information that is specific to the legacy version of the driver framework (DFv1).
Device firmware are binary blobs containing code that are executed by device hardware. The binary blob is available in the driver's namespace for loading.
Device firmware are stored in CIPD (Chrome Infrastructure Package Deployment) and mirrored in Google Storage.
To create a firmware package, create a directory containing the following files:
README.fuchsia must contain at least the following directives:
Name
Version
Upstream Git
License
License File
If this is the first time you uploaded to CIPD from the host system, authenticate with CIPD:
fx cipd auth-login
Upload and tag the package in CIPD using the following command:
fx cipd create -in <package-directory> -install-mode copy \ -name <package-name> \ -tag git_repository:<source-git-repositry> \ -tag git_revision:<source-git-revision>
package-name
has the format fuchsia/firmware/<name>
.
<name>
should be a string that identifies the firmware. It may contain any non-whitespace character. It is helpful to identify the driver that will use the firmware in the name.
After this step, the package is uploaded to CIPD. Check the CIPD browser here for packages under fuchsia/firmware
.
This must be done in the integration.git
repository. See the firmware
file in the open-source repository for examples.
