Appendix - BMC and ERoT Upgrade Process for BlueField-2

To upgrade BlueField BMC firmware on a BlueField-2 device, follow this procedure:

Download openbmctool v1.22 and resolve dependencies.
- sudo pip3 install paramiko
- sudo pip3 install scp

Trigger BMC update.

python3 openbmctool.py -H <bmc_ip> -U root -P <password> firmware flash bmc -f <path-to-signed-bmc-image>

After initiating the BMC firmware secure update, a new task is created. Example:

Attempting login...
Uploading file to BMC
Upload complete.
Firmware activation is in progress. Please wait for activation task id="0" to get completed before rebooting the bmc.
User root has been logged out

BMC firmware update takes 15-20 mins.

Track the progress of the update by using the task Id received in the response above (i.e., 0) in your query and monitoring the value of the task’s TaskProgress field.
```
python3 openbmctool.py -H <bmc_ip> -U root -P <password> task status -i <task_Id>
```
Before proceeding to other operations. Keep running this command until it outputs:
```
TaskState="Completed"
TaskStatus="OK"
TaskProgress="100"
```
Reset/reboot the BMC.

This step may be skipped if you intend to perform eROT update.
To query the installed version, run:
```
python3 openbmctool.py -H <bmc_ip> -U root -P <password> firmware running_version
```
The BlueField-2 BMC takes about 2.5 minutes to complete boot.

Wait a few seconds before attempting to log back into the BMC as it loses connection during and shortly after reboot.

Trigger eROT update.

python3 openbmctool.py -H <bmc_ip> -U root -P <password> apfirmware flash cec -f <path-to-signed-CEC-OTA-image-file>

After initiating the eROT update, the following indication is provided:

Uploading firmware image: 100.00%
Firmware update for cec triggered successfully.

Perform host power cycle for the eROT update to take effect:
```
sudo ipmitool power cycle
```
