model_sku

Source code: model_sku.py

A test to confirm and set SKU information.

Description

A test to confirm SKU information, then apply SKU or model specific settings. And there are two modes:

1. manually ask to operator to confirm SKU information.

2. automatically compare SKU information with device data - component.sku.

If device data - component.sku is set then this test will go to automatic mode or manual mode will be executed.

This is a test to verify hardware root of trust, so there’s no options to set auto verification for this test. Instead, either it relies on the operator to check manually or compares with device data from shopfloor which would need to be configured in advance.

After the SKU is confirmed, the test will load a JSON configuration specified by config_name. The config should be a dictionary containing what device data (usually component.*) to set for matched model and SKU. For example, to set if the touchscreen is available for model ‘coral’ with default True, and only False for product_name Coral SKU 3:

{
  "model": {
    "coral": {
      "component.has_touchscreen": true
    }
  },
  "product_sku": {
    "Coral": {
      "3": {
        "component.has_touchscreen": false
      }
    }
  }
}

Test Procedure

The test runs following commands:

• cros_config / name

• cros_config /identity sku-id

• cros_config / brand-code

And then asks OP to press ENTER/ESC to confirm if these values are correct.

Dependency

• mosys utility.

Examples
