Running Out-of-Box (OOB) Demo Code

- Attestation (SPDM) demo
MEC1723 send a sequence of I2C commands to CEC1736 to fetch the entire
certification chain from internal flash, then do the verification, then send “Chal-
lenge authentication” to CEC1736 to get the NONCE data and its signature back,
and then verify the signature of the NONCE data. All the steps & status, data will
output to UART logs.
3. Revocation demo
- Key Revocation
This demo will show how MEC1723 will fail to load an image after the key is
revoked; all steps & status will output to UART logs.
- Roll back protection
This demo will show how MEC1723 will fail to load an older image after the FW
revision has been updated; all steps & status will output to UART logs.
The following step-by-step example shows CEC1736 Serial UART logs after the initial
power-up of the development board:
1. Plug-in a Micro-USB Cable from a PC USB Port to CEC1736 Development
Board P2 Micro-USB Port for CEC1736, as shown in Chapter 4
2. Plug-in another Micro-USB Cable from a PC USB Port to CEC1736 Develop-
ment Board P3 Micro-USB Port for MEC1723, as shown in Chapter 4
3. The connected PC Windows Device Manager should have the two USB Serial
Ports (ex: COM7, COM8 as shown below) detected.
Note:
Demos #1 demo is planned to be included and programed to the develop-
ment board. Demos #2, #3, #4 and other future development demos will be
included in a separated OOB Host sample code package releases from
SDE when they’re available.
