| DOC = """ |
| This test replaces chip (i.e. TCPC) firmware on the DUT's bios.bin |
| and reboots into it. The expectation is that the TCPC firmware |
| is updated correctly when the system boots with the updated bios.bin |
| |
| Software sync applies the TCPC firmware update and verifies that |
| it has been applied. If the DUT rebooted successfully, we know |
| that the test has passed. |
| |
| For independent verification, the firmware_CompareChipFwToShellBall |
| FAFT test can be used to verify the running TCPC firmware versions. |
| |
| For complete testing, this test needs to be invoked to downgrade, then |
| upgrade the TCPCs so that we have confidence that the update process |
| really happened. |
