3. Compare the retrieved version information with the minimum versions (if provided).

Dependency

• ectool

Examples

To check if the PDC firmware version is “0.0.0.0.0.0.27.1”:

{
  "pytest_name": "check_pdc_firmware",
  "args": {
    "expected_fw_version_dec": "0.0.0.0.0.0.27.1",
    "expected_fw_name_str": "GOOG0000",
    "expected_driver_name": "realtek_rts54_pdc",
    "usb_pd_id": 0
  }
}

To check if the PDC firmware version is at least “0.0.0.0.0.0.27.0”:

{
  "pytest_name": "check_pdc_firmware",
  "args": {
    "min_fw_version_dec": "0.0.0.0.0.0.27.0",
    "usb_pd_id": 0
  }
}
