pd_fw_min_version

Source code: pd_fw_min_version.py

Check firmware version of PD (TCPC) chip equal to or larger than minimum version noted in corresponding EC driver.

Description

Some PD chip might have issues which need to be solved by the cooperation between firmware of PD chip and corresponding EC driver. In order to make sure PD chips are shipped with correct firmware version, this test asks two info from EC via ectool; one is current firmware version and the other is the minimum required firmware version. Then these two versions would be compared to confirm firmware version in the PD chip is greater then or equal to minimum required version.

Test Procedure

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

Dependency

• DUT link must be ready before running this test.

• ectool utility.

Examples

To verify PD chip in the port 0, add this in test list:

{
  "pytest_name": "pd_fw_min_version"
}

To verify multiple PD chips (ex: port 0 and 1), add this in test list:

{
  "pytest_name": "pd_fw_min_version",
  "args": {
    "ports": [0, 1]
  }
}

Test Arguments

Name	Type	Description
ports	int, list	(optional; default: 0) Specify which PD ports are checked.
