update_cbi

Source code: update_cbi.py

A test to update CBI data to EEPROM.

Description

A test to set CBI data from device data to EEPROM by using ectool cbi. Available device data are component.sku, component.dram_part_num and component.pcb_supplier. When updating the SKU ID, if the FW Config can be queried from the cros_config, then the FW Config will be updated as well. If you want to run the pytest model_sku with the SKU ID set by this pytest, you need to reboot the DUT first.

Test Procedure

This is an automatic test that doesn’t need any user interaction.

Dependency

• ectool utility.

• cros_config_mock utility.

• chromeos-base/cros-config-api.

Examples

To set SKU_ID, DRAM_PART_NUM and PCB_SUPPLIER from device data to CBI, add this in test list:

{
  "pytest_name": "update_cbi",
  "args": {
    "cbi_data_names": ['SKU_ID', 'DRAM_PART_NUM', 'PCB_SUPPLIER']
  }
}

To set SKU ID and run the pytest model_sku, add this in test list:

{
  "subtests": [
    {
      "pytest_name": "update_cbi",
      "args": {
        "cbi_data_names": ['SKU_ID']
      }
    },
    "FullRebootStep",
    {
      "pytest_name": "model_sku"
    }
  ]
}

Test Arguments

Name	Type	Description
cbi_data_names	list	List of CBI data names to update
force	bool	(optional; default: False) If true then overwrite settings even if the sku_id is the same.
sku_id_source	[‘device_data’, ‘hardcode’]	(optional; default: <SKUIDSource.device_data: 'device_data'>) The source of sku_id.
hardcode_sku_id	int, None	(optional; default: None) The hard-code sku_id.
config_source	[‘config_jsonproto’, ‘cros_config_mock’, ‘model_sku’]	(optional; default: <ConfigSource.cros_config_mock: 'cros_config_mock'>) The source of updating data.
program	str, None	(optional; default: None) The program of the device.
project	str, None	(optional; default: None) The project of the device.
product_name	str, None	(optional; default: None) The product_name of the device. If not specified, read from /sys/class/dmi/id/product_name on x86 devices and /proc/device-tree/compatible on ARM devices.
