flash_tool

Overview ¶

flash_tool is a util to flash firmware update packages created by the publisher tool onto devices.

Currently, the only device is a dummy device, which simply sorts the firmware+metadata on local disk.

Usage:

go run ./cmd/flash_tool/ --logtostderr --dummy_storage_dir=/path/to/dir --update_file=/path/to/update.json

The first time you use this tool there will be no prior firmware metadata stored on the device and the tool will fail. In this case, use the --force flag to apply the update anyway thereby creating the metadata. Subsequent invocations should then work without needing the --force flag.
