Re: [edk2-devel] Help getting Capsule-On-Disk working (CapsuleOnDiskLoadPei and gEdkiiPeiBootInCapsuleOnDiskModePpiGuid)

["Xu, Wei6 via groups.io" <wei6.xu=intel.com@groups.io>]

Hi Rebecca,

Yes, you are right. CapsuleOnDiskLoadPei should be used, and platform code is supposed to produce the gEdkiiPeiBootInCapsuleOnDiskModePpiGuid.
Please refer this guide: https://github.com/tianocore/edk2-staging/tree/UEFI_CapsuleOnDisk?tab=readme-ov-file#how-to-enable-capsule-on-disk

BR,
Wei
