Vijay, 

- How are you able to determine flash ranges used by UEFI in case we may not want to update ME but only UEFI regions?  
- How is this interfaced from redfish/IPMI ? 

Is there any design document for this feature that we can review? 

Neeraj

Hi Medad,

To set up ME in Recovery mode use IPMI command “Force ME Recovery” – DFh (byte4=01h)
To set up ME in Operational again use IPMI “Cold Reset” command” – 02h

Hi Vijay,

I try to upgrade BIOS from BMC, but I do not know how to set the mode of  ME/NM.
Can you share the process how you set ME/NM to recovery mode and operation mode?

Thanks.

Hi,
I am writing an application for Bios upgrade. Currently I have created a hook to our bmc updater which expects a systemd unit file to be run at the time of activating update. But I am thinking of adding some of this unit file functionality in updater itself and wanted to run by you all if it is common procedure used by every platform. Below are the process we use in our platform as a part of bios upgrade.

1. Power off host server.
2. Set ME/NM (Management engine or Node manager in x86) to recovery mode
3. Flip GPIO to access SPI flash used by host.
4. Bind spi driver to access flash
5. Flashcp image to device.
6. Unbind spi driver
7. Flip GPIO back for host to access SPI flash
8. Set ME/NM to operational mode
9. Power on server.

I can have some flexibility in this sequence based on each platform configuration. Looking forward to your suggestions.

Regards
-Vijay
