Baytrail + coreboot + Tianocore information request.

[JTruj2]

This request was intended for the Intel's Firmware support team but

they never replied to my requests from months ago neither this one, not even

an automated confirmation reply.

So, I hope anyone of you can help me or redirect me to someone else (who really can do that).

This is the letter I sent to them:

-----------------------------------------

Dear Firmware support team:

Actually I am interested in creating a full featured firmware based in coreboot + tianocore.

The coreboot initialization stage is almost ready.

My system is based on SOC Baytrail E3845

I am already running tianocore but I would like to configure it properly.

I am would like to learn how to make tianocore to:

1.- Save the boot (and other) settings to NVS or CMOS.

2.- Scan for bootable partitions and USB drives.

3.- To get the ability to do secure boot.

4.- How to handle hardware TPM

5.- To create applications.

6.- If possible to also learn how to add a CSM module to be able to boot Legacy partitions.

This information is scarce and confusing on the internet and this is why I need help.

I use Linux Fedora but also can use Windows.

Please give me guidance on those issues or/and point me to the right literature/information.

I already have privileged account with intel.

Thank you in advance.

Hello RTS_JT

I am assuming that what you mean by Using Coreboot with TianoCore is that you want to Create create an EDKII Tianocore Image and use it as payload for your platform?

I can provide some documentation that might be useful for your case:

Regarding CSM module you might find this useful: Sea BIOS can be configured as a CSM module to be integrated with EDKII: https://www.seabios.org/Build_overview# Build_as_a_UEFI_Compatibility_Support_Module_.28CSM.29 https://www.seabios.org/Build_overview# Build_as_a_UEFI_Compatibility_Support_Module_.28CSM.29

Here you can find additional documentation about Tiano Core:

I specially recommend the Beyond BIOS documents as they explain many topics including TPM

Tiano Core Basic documentation: https://github.com/tianocore/tianocore.github.io/wiki/EDK-II-User-Documentation EDK II User Documentation · tianocore/tianocore.github.io Wiki · GitHub

Tiano Core White Papers: https://github.com/tianocore/tianocore.github.io/wiki/EDK-II-white-papers EDK II white papers · tianocore/tianocore.github.io Wiki · GitHub

Here is more information regarding TPM: https://firmware.intel.com/sites/default/files/resources/A_Tour_Beyond_BIOS_Implementing_TPM2_Support_in_EDKII.pdf https://firmware.intel.com/sites/default/files/resources/A_Tour_Beyond_BIOS_Implementing_TPM2_Support_in_EDKII.pdf

I also suggest to suscribe to the Tiano Core Developers mailing list: http://sourceforge.net/apps/mediawiki/tianocore/index.php?title=Mailing_Lists http://sourceforge.net/apps/mediawiki/tianocore/index.php?title=Mailing_Lists

I hope this information is useful for your case.
