Fmp Payload Header Usage

Fmp Payload Header Usage

[Ashish Singhal]

Hello Michael/Liming,

I am trying to use FmpDevicePkg for FMP based capsule update and am failing in FmpPayloadHeaderLib while verifying FMP payload header. I am building capsule and payload using FDF file itself and not calling Capsule tools explicitly from basetools. Is there a special build flag I need to provide to add FMP payload header to my payload?

Thanks
Ashish

Hi Ashish,

You do need to use the standalone tool called GenerateCapsule to convert
a payload to a UEFI Capsule.

Here is an example:

https://github.com/tianocore/edk2/blob/master/Vlv2TbltDevicePkg/Feature/Capsule/GenerateCapsule/GenCapsuleMinnowMax.bat

You can customize this script for your platform.  This script is for
dev/debug purposes only for use on a local dev system.  It supports
different keys and tools to generate a UEFI Capsule.  You can simplify
it for a specific tool/key option.

You can integrate this into the standard build process by adding a
script to the DSC file as a post build step.

https://github.com/tianocore/edk2/blob/master/Vlv2TbltDevicePkg/PlatformCapsule.dsc

  POSTBUILD = Vlv2TbltDevicePkg/Feature/Capsule/GenerateCapsule/GenCapsuleAll.bat

This specific platform has some extra steps that need to be 
performed after the normal build of the FW image before the capsule
is generated, so a 2nd DSC/FDF file is used.  If you do not have 
any extra steps, then you can add the POSTBUILD statement to the
[Defines] section of your platform DSC file.

Best regards,

Mike
