Hi,
I need your help in running SCT from SD card on Freescale SoC.
I have built SCT and copied following images on SD card (formatted with FAT32),
inserted this SD card in my board:
1.EdkShellBinPkg/FullShell/Arm/Shell_Full.efi
2.Build/UefiSct/DEBUG_ARMGCC/SctPackageAARCH64/AARCH64/*
On running shell I saw following entry:
UEFI Interactive Shell v2.1
EDK II
UEFI v2.40 (LS1043a Simulator EFI Jul 15 2015 16:55:13, 0x00000000)
Mapping table
FS0: Alias(s):HD0mohuqyt:;BLK0:
HD(-1225503552,175,0,0x20021BE11DF9E45,0xAFAFAFAF1BC5D5A5)
I am not getting from where it is populating these values of HD().
Now on selecting FS0, I saw following prints:
Shell> fs0:
FS0:\> ls
Get RTC Year: 15 Mon: 07 Day: 15 Hour: 17 Min: 24 Sec: 59
Get DATE: 2015-07-15 TIME: 17:24:59
FSOpen: Open '.' Success
File Not Found
FS0:\>
My UEFI binary has support of SD card, I can probe a card and its read, write
and erase functionalities are working fine.
I want to execute SCT.efi using shell. Kindly help me with this
Along with the above issue, I am seeing following failures in OpenVolume() call:
FATDirSize: cluster chain corrupt
*OutputFileName 0x61
*OutputFileName 0x62
*OutputFileName 0x63
FatGrowEof: cluster chain corrupt
FatShrinkEof: cluster chain corrupt
What is the reason behind these prints?
Regards
Meenakshi

UEFI specification says 'HD(Partition,Type,Signature,Start, Size)'.
These values are specific to you partition table.
gArmPlatformTokenSpaceGuid.PcdDefaultBootDevicePath is specific to the ARM BDS.
It is to create a default boot entry when you start your system for a first
time.
It is not (necessary) relevant to boot Linux or run SCT on your platform.
I would say you have the appropriate list of EFI modules to get FAT support (if
you already have SD support in your UEFI firmware).

Subject: [edk2] Filesystem support
Hi All,
I want to boot linux and run SCT from SD card.
I have seen BeagleBoard package code which is booting linux from SD.
I got confused with entry:
gArmPlatformTokenSpaceGuid.PcdDefaultBootDevicePath|L"VenHw(B615F1F5-5088-43CD-809C-A16E52487D00)/HD(1,MBR,0x00000000,0x3F,0x19FC0)/zImage"
from where are 0x3F and 0x19FC0 came. Is it some default value for start
address and size?
Do I need to create an FV entry for this?
Also what all I need to include in my dsc and fdf file to enable support of
filesystem. I can see following listed files for filesystem support (reference
: BeagleBoard)
Changes in FDF:
#
# FAT filesystem + GPT/MBR partitioning
#
INF MdeModulePkg/Universal/Disk/DiskIoDxe/DiskIoDxe.inf
INF MdeModulePkg/Universal/Disk/PartitionDxe/PartitionDxe.inf
INF FatBinPkg/EnhancedFatDxe/Fat.inf
INF MdeModulePkg/Universal/Disk/UnicodeCollation/EnglishDxe/EnglishDxe.inf
Changes in DSC
#
# FAT filesystem + GPT/MBR partitioning
#
MdeModulePkg/Universal/Disk/DiskIoDxe/DiskIoDxe.inf
MdeModulePkg/Universal/Disk/PartitionDxe/PartitionDxe.inf
MdeModulePkg/Universal/Disk/UnicodeCollation/EnglishDxe/EnglishDxe.inf
Thanks & regards
