| This test verified the EC software sync. The EC binary is embedded in |
| the BIOS image. On AP startup, AP verifies the EC by comparing the |
| hash of the current EC with the hash of the embedded EC image. So |
| updating EC is simple and we just need to change the EC binary on |
| the BIOS image. |
| |
| The test steps are: |
| 1. check EC is RO boot and AP is RO boot, |
| extract the original EC binary on current AP RW A and save it locally, |
| copy the new_ec binary to the EC area on the current AP RW A, |
| disable RO_BOOT preamble flag, |
| reboot; |
| 2. check EC is RW boot and AP is RW A boot, |
| compare the current EC with the new_ec binary, |
| copy the original EC binary to the EC area on the current AP RW A, |
| reboot; |
| 3. check EC is RW boot and AP is RW A boot, |
| compare the current EC with the original EC binary, |
| enable RO_BOOT preamble flag, |
| reboot; |
| 4. check EC is RO boot and AP is RW A boot. |
| |
| So RONORMAL->TWOSTOP, TWOSTOP->TWOSTOP, and TWOSTOP->RONORMAL are covered. |
