Back to Capsule Based System Firmware Update

The following steps can be used to verify that the capsule-based system firmware update feature has been integrated into a platform correctly. This example uses the Intel® Galileo Gen 2 platform. These steps use the test signing keys, and it is a good idea to verify this update feature using the test signing keys before using product specific signing keys.

NOTE: Each step in this sequence depends on all the previous steps. If any step in this sequence does not match expectations, then debug and resolve the integration issue before proceeding to the next step.

OpenSSL Patch for CryptoPkg

This build process uses EDK II CryptoPkg, which requires a patch to be applied from OpenSSL. Please verify this process has been completed before proceeding to the next step, otherwise the build will fail.

Build and Boot Firmware Image

  • Build firmware image setting the -D CAPSULE_ENABLE flag

build -a IA32 -t VS2015x86 -p QuarkPlatformPkg/Quark.dsc -D CAPSULE_ENABLE

  • Update target with new firmware image
  • Boot target to Boot Manager. The front page should show a WARNING: Test key detected. message informing the user that a test signing key is in use and that this firmware image is only for development/debug purposes. If logging is enabled, then this same message is displayed in that log.

   Reset
  • Boot target to UEFI Shell

Verify Capsule Structures

  • Copy CapsuleApp.efi to a USB drive
  • Attach USB drive withCapsuleApp.efi
  • Run CapsuleApp.efi with no parameters to see the help information
CapsuleApp:  usage
  CapsuleApp <Capsule...>
  CapsuleApp -S
  CapsuleApp -C
  CapsuleApp -P
  CapsuleApp -E
  CapsuleApp -G <BMP> -O <Capsule>
  CapsuleApp -N <Capsule> -O <NestedCapsule>
  CapsuleApp -D <Capsule>
Parameter:
  -S:  Dump capsule report variable (EFI_CAPSULE_REPORT_GUID),
       which is defined in UEFI specification.
  -C:  Clear capsule report variable (EFI_CAPSULE_RPORT_GUID),
       which is defined in UEFI specification.
  -P:  Dump UEFI FMP protocol info.
  -E:  Dump UEFI ESRT table info.
  -G:  Convert a BMP file to be a UX capsule,
       according to Windows Firmware Update document
  -N:  Append a Capsule Header to an existing capsule image,
       according to Windows Firmware Update document
  -O:  Output new Capsule file name
  -D:  Dump Capsule image header information and FMP header information,
       if it is an FMP capsule.
  • Run CapsuleApp.efi -P to view the Firmware Management Protocol details. The details should match the System Firmware Descriptor PEIM .aslc file described here. In this example, the ImageTypeId GUID value is 553B20F9-9154-46CE-8142-80E2AD96CD92, the Version value is 0x3 and the VersionName string is "0x00000003".

Build System Firmware Update Capsule

  • Update System Firmware Descriptor PEIM .aslc file to a higher version by updating the CURRENT_FIRMWARE_VERSION and CURRENT_FIRMWARE_VERSION_STRING defines. This file is described here
  • Build firmware image again setting the -D CAPSULE_ENABLE flag

build -a IA32 -t VS2015x86 -p QuarkPlatformPkg/Quark.dsc -D CAPSULE_ENABLE

Verify System Firmware Update Capsule

  • Copy System Firmware Update Capsule Image with higher version to a USB drive
  • Run CapsuleApp.efi -D <CapsuleImage> to dump capsule image header information. The UpdateImageTypeId value is the same as the ESRT FwClass value is also the same as the Firmware Management Protocol ImageTypeId GUID value of 553B20F9-9154-46CE-8142-80E2AD96CD92.
