Re: Help. SBL versioning
by Gudla, Raghava
Hi Gustavo,
Command looks correct, please make sure you have sbl.bios.bin generated using stitchloader.py before using the command.
SBL is now using chipset sticky register instead of CMOS to trigger firmware update. We have updated documentation on this today, please look at https://slimbootloader.github.io/supported-hardware/apollo-lake-crb.html#...
Triggering firmware update from Windows is now supported. Please see https://slimbootloader.github.io/security/firmware-update.html#trigger-up... to understand about this feature.
Thank you,
Raghava

Subject: RE: Help. SBL versioning
Hi,
Using the commands you mentioned I could generate the capsule update but I had to modify the comand:
python ./BootloaderCorePkg/Tools/GenCapsuleFirmware.py -v -p BIOS sbl_lfh_ifwi.bin -k ./BootloaderCorePkg/Tools/Keys/TestSigningPrivateKey.pem -o FwuImage.bin
by
python ./BootloaderCorePkg/Tools/GenCapsuleFirmware.py -v -p BIOS sbl.bios.bin -k ./BootloaderCorePkg/Tools/Keys/TestSigningPrivateKey.pem -o FwuImage.bin
Is it correct?
I have another issue, reading section "Triggering Firmware Update" in https://slimbootloader.github.io/supported-hardware/apollo-lake-crb.html#..., I am trying to use CMOS register to trigger firmware update but it doesn't work like it is described. I have seen IsFirmwareUpdate function was modified in this commit https://github.com/slimbootloader/slimbootloader/commit/f6fd3a3f06db8b102...:
Before modification, the function only read the register:
IoWrite8 (0x70, FWU_BOOT_MODE_OFFSET);
FirmwareUpdateStatus = IoRead8 (0x71);
But the present repository code has more logic. How can I trigger firmware update from OS using the master branch code?
Thanks,
Gustavo.

Asunto: RE: Help. SBL versioning
Hello,
Whole IFWI should not be used to create capsule. Only BIOS region is required to create capsule.
Please look at "Slimbootloader binary for capsule image" section in https://slimbootloader.github.io/supported-hardware/apollo-lake-crb.html to understand how to create bios region for the capsule.
In your case, after you stitch IFWI, use the following command
python Platform/ApollolakeBoardPkg/Script/StitchLoader.py -b sbl.bios.bin -i APL_SBL_IFWI.bin -s Outputs/apl/Stitch_Components.zip -o sbl_lfh_ifwi.bin
python ./BootloaderCorePkg/Tools/GenCapsuleFirmware.py -v -p BIOS sbl_lfh_ifwi.bin -k ./BootloaderCorePkg/Tools/Keys/TestSigningPrivateKey.pem -o FwuImage.bin
You can use FwuImage.bin to perform capsule update.
Please let us know if you see any other issues.
Thank you,
Raghava

Asunto: RE: Help. SBL versioning
Hi,
There is one more thing missing in your patch.
Since you are using OsLoader to boot Linux instead of UEFI payload, you will need to keep a SMBIOS entry record at legacy F segment so that non-UEFI boot can find the SMBIOS table accordingly.
You can try to add the following. I can try to submit a PR in the open source SBL to add this part. 0xFFF60 is hardcoded here for SMBIOS. We do the similar for ACPI table at address 0xFFF80.

Subject: RE: Help. SBL versioning
Hi,
The platform I am using is Apollolake. I have added the function InitializeSmbiosInfo from https://github.com/slimbootloader/slimbootloader/blob/master/Platform/Cof...<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_slimbootl...> to https://github.com/slimbootloader/slimbootloader/blob/master/Platform/Apo... and I call this function from BoardInit.
I have modified the file https://github.com/slimbootloader/slimbootloader/blob/master/Platform/Apo... including the following lines:
gPlatformModuleTokenSpaceGuid.PcdSmbiosStringsPtr
gPlatformModuleTokenSpaceGuid.PcdSmbiosStringsCnt
gPlatformModuleTokenSpaceGuid.PcdSmbiosTablesBase
gPlatformModuleTokenSpaceGuid.PcdSmbiosEnabled
I have also added the line "self.ENABLE_SMBIOS = 1" in https://github.com/slimbootloader/slimbootloader/blob/master/Platform/Apo...
After all of this, I boot the system but when I try run "dmidecode -t bios -q" the output is empty. If I run "dmidecode" without parameters I get:
# dmidecode 3.1
Scanning /dev/mem for entry point.
# No SMBIOS nor DMI entry point found, sorry.
I attach part of the modified files (maybe the patch is not correct, I think some include files are not necessary):

Asunto: RE: Help. SBL versioning
Yes, the standard way to retrieve BIOS version in user space is through SMBIOS table.
There are standard tools to do this. You might need admin/root access though.
In Windows, you can use
"wmic bios get smbiosbiosversion"
In Linux, you can use
"dmidecode -t bios -q"
In SBL, you will need to enable the SMBIOS for the project. Currently in the SBL repo, only CFL enabled SMBIOS by default.
For other projects, it needs some porting to enable it as Guo mentioned.
Thanks
Maurice

Hi,
Please try if you could get the version information from SMBIOS table?
SBL should put these information into SMBIOS table.
Please refer InitializeSmbiosInfo () in
https://github.com/slimbootloader/slimbootloader/blob/master/Platform/Cof...
Thanks,
Guo

Subject: [Sbl-devel] Help. SBL versioning
Hello,
First of all sorry if the question makes no sense but I am new using SBL.
At this moment I have a SBL in my board that boot the Os using the payload "Os Loader".
The OS is Linux distro generated using Yocto. I don't know how to get the SBL version from user space in Linux.
I have read the versioning documentation page (https://slimbootloader.github.io/developer-guides/versioning.html) but I don't know how to access to the HOB data list with GUID gBootLoaderVersionGuid.
Could someone tell me how to access the version of SBL from Linux?
Best regards.
1 year, 10 months
Re: Help. SBL versioning
by Ma, Maurice
Thank you for providing updates back. Glad to see it worked for you.
BTW, since you enabled /ported the SMBIOS for APL, are you willing to push this change back into the github ? :)
Thanks
Maurice

Hi,
This worked well for me! Adding the line Maurice mentioned in the previous message I can get BIOS information using the command "dmidecode -t bios -q".
Thank you all for your help.

Asunto: RE: Help. SBL versioning
Hi,
There is one more thing missing in your patch.
Since you are using OsLoader to boot Linux instead of UEFI payload, you will need to keep a SMBIOS entry record at legacy F segment so that non-UEFI boot can find the SMBIOS table accordingly.
You can try to add the following. I can try to submit a PR in the open source SBL to add this part. 0xFFF60 is hardcoded here for SMBIOS. We do the similar for ACPI table at address 0xFFF80.

Hi,
The platform I am using is Apollolake. I have added the function InitializeSmbiosInfo from https://github.com/slimbootloader/slimbootloader/blob/master/Platform/Cof...<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_slimbootl...> to https://github.com/slimbootloader/slimbootloader/blob/master/Platform/Apo... and I call this function from BoardInit.
I have modified the file https://github.com/slimbootloader/slimbootloader/blob/master/Platform/Apo... including the following lines:
gPlatformModuleTokenSpaceGuid.PcdSmbiosStringsPtr
gPlatformModuleTokenSpaceGuid.PcdSmbiosStringsCnt
gPlatformModuleTokenSpaceGuid.PcdSmbiosTablesBase
gPlatformModuleTokenSpaceGuid.PcdSmbiosEnabled
I have also added the line "self.ENABLE_SMBIOS = 1" in https://github.com/slimbootloader/slimbootloader/blob/master/Platform/Apo...
After all of this, I boot the system but when I try run "dmidecode -t bios -q" the output is empty. If I run "dmidecode" without parameters I get:
# dmidecode 3.1
Scanning /dev/mem for entry point.
# No SMBIOS nor DMI entry point found, sorry.
I attach part of the modified files (maybe the patch is not correct, I think some include files are not necessary):

Asunto: RE: Help. SBL versioning
Yes, the standard way to retrieve BIOS version in user space is through SMBIOS table.
There are standard tools to do this. You might need admin/root access though.
In Windows, you can use
"wmic bios get smbiosbiosversion"
In Linux, you can use
"dmidecode -t bios -q"
In SBL, you will need to enable the SMBIOS for the project. Currently in the SBL repo, only CFL enabled SMBIOS by default.
For other projects, it needs some porting to enable it as Guo mentioned.
Thanks
Maurice

Hi,
Please try if you could get the version information from SMBIOS table?
SBL should put these information into SMBIOS table.
Please refer InitializeSmbiosInfo () in
https://github.com/slimbootloader/slimbootloader/blob/master/Platform/Cof...

Subject: [Sbl-devel] Help. SBL versioning
Hello,
First of all sorry if the question makes no sense but I am new using SBL.
At this moment I have a SBL in my board that boot the Os using the payload "Os Loader".
The OS is Linux distro generated using Yocto. I don't know how to get the SBL version from user space in Linux.
I have read the versioning documentation page (https://slimbootloader.github.io/developer-guides/versioning.html) but I don't know how to access to the HOB data list with GUID gBootLoaderVersionGuid.
Could someone tell me how to access the version of SBL from Linux?
Best regards.

Re: Help. SBL versioning

Hi,
There is one more thing missing in your patch.
Since you are using OsLoader to boot Linux instead of UEFI payload, you will need to keep a SMBIOS entry record at legacy F segment so that non-UEFI boot can find the SMBIOS table accordingly.
You can try to add the following. I can try to submit a PR in the open source SBL to add this part. 0xFFF60 is hardcoded here for SMBIOS. We do the similar for ACPI table at address 0xFFF80.

Hi,
The platform I am using is Apollolake. I have added the function InitializeSmbiosInfo from https://github.com/slimbootloader/slimbootloader/blob/master/Platform/Cof...<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_slimbootl...> to https://github.com/slimbootloader/slimbootloader/blob/master/Platform/Apo... and I call this function from BoardInit.
I have modified the file https://github.com/slimbootloader/slimbootloader/blob/master/Platform/Apo... including the following lines:
gPlatformModuleTokenSpaceGuid.PcdSmbiosStringsPtr
gPlatformModuleTokenSpaceGuid.PcdSmbiosStringsCnt
gPlatformModuleTokenSpaceGuid.PcdSmbiosTablesBase
gPlatformModuleTokenSpaceGuid.PcdSmbiosEnabled
I have also added the line "self.ENABLE_SMBIOS = 1" in https://github.com/slimbootloader/slimbootloader/blob/master/Platform/Apo...
After all of this, I boot the system but when I try run "dmidecode -t bios -q" the output is empty. If I run "dmidecode" without parameters I get:
# dmidecode 3.1
Scanning /dev/mem for entry point.
# No SMBIOS nor DMI entry point found, sorry.
I attach part of the modified files (maybe the patch is not correct, I think some include files are not necessary):
