Thanks, Bob -----Original Message----- From: devel@edk2.groups.io <devel@edk2.groups.io> On Behalf Of Bob Feng Sent: Monday, November 9, 2020 9:57 AM To: devel@edk2.groups.io Cc: Yunhua Feng <fengyunhua@byosoft.com.cn>; Liming Gao <gaoliming@byosoft.com.cn> Subject: [edk2-devel] [Patch] [edk2-staging]BaseTools/Bfm: Apply the FMMT algorithm of LibFindFvInFd The LibFindFvInFd algorithm of FMMT and BFM are different. The LibFindFvInFd in FMMT is the correct one. By applying FMMT LibFindFvInFd, BFM can handle the case that there are two same bios images in one Firmware binary.
