Re: [coreboot] UEFI Payload in coreboot for Intel Minnowboard or Bayley bay

Hi Zoran

Sorry, but I am not able to understand what you have mentioned.

Can you please help me explain little detail?

Sorry, but I am new to this coreboot environment.

Mayuri

Hello Mayuri,

Not sure if I am right, but to bring GRUB 2.0 from CSM OFF and CSM ON modes, you must have two distinct HDDs, one created with CSM ON, other with CSM OFF. If you are using one with CSM ON (seems the case), your UEFI payload will not find EFI32 /boot/EFI directory created, and it does not understand MBR).

Does this (what I wrote) make sense?

Hi Zoran

Currently we are using FSP 3. But it works fine with seabios payload.

Only when I include UEFI, I am getting this issue. So I am not sure if this is related to FSP3 or 4.

My query is there any additional configurations required in UEFI Payload to make it work for Minnowboard max.

I see difference in addresses for UEFI and Seabios payload. Not sure where are they set.

Hello Mayuri,

If I am not mistaken (I often mix BYT Coreboot @ threads in my head), you are using BYT FSP Version 3.
> fsp_header_ptr: fffc0094 <== correct
> FSP Header Version: 1
> FSP Revision: 3.3 <== please, use Version 4

Please, try to use the latest public BYT FSP Version 4 posted at: www.intel.com/fsphttp://www.intel.com/fsp

BAYTRAIL_FSP_GOLD_004_22-MAY-2015.fd
BAYTRAIL_FSP_GOLD_004_22-MAY-2015_DEBUG.fd

Don't remember deltas between V3 and V4, I thing something was wrong in V3 with MTRRs' setup, if I do not mix data in my head.

INTEL also has Version 5 for a quite some time, but this one for some reasons never got publicly released.

Please, report if this solved your problems.

Hi

While booting my Minnomboard with coreboot and UEFI, it hangs at below point while loading the payload.

I followed the procedure to download latest EDK2 tree and built UEFIPAYLOAD.fd and copied it to coreboot/payloads/external/tianocore folder and gave this path in make menuconfig.

Has anybody come across this?

Hi Zoran and Martin

Today I was able to build UEFIPAYLOAD separately. I included .fd file while building coreboot.rom.

But while booting, getting some errors , so debugging those.

Need to check what more customizations to be done in UEFI for Minnowmax.

Has anybody tried it?

Mayuri

OK, Mayuri,

You brought an interesting point. And this point is to be not only investigated by you, rather also by me and, perhaps, Coreboot community.

Since here, in Bayern/Deutschland is Holiday Day, I went to buy a beer in Munchen HBf, and while walking there I was thinking about your use case. Thinking deeper.

I know that you are using some INTEL CPU/SoC (do not remember which one, if you said one). But, while recapping how BIOS looks like, I did notice that SEC and PEI phases have nothing to do with UEFI EDK2. EDK 2 comes to play in DXE phase, where EDK2 actually takes place/overtakes control...

It says to me one major thing I did not notice while ago: that ARM SoCs are also eligible to run on UEFI compliant OSes, namely WIN 8.1+ (including WIN 10 and WIN 10 Athens/RT WIN 10). Which makes very interesting IOT case namely for ARM, allowing it also to compete in WIN space.

Interestingly enough, this idea did not come to my mind till few hours ago... I guess, Vincent (Zimmer) already thought about that. ;-)
_______

Martin (Roth) just replied, to solve this immediate mystery. probably for the beginning only for INTEL SoCs, but, I really hope, ARM will also integrate in this concept seamlessly! :-)

Hi Zoran

I have checked that site and downloaded EDK2 code. I am trying to build it on Linux but facing some issues.
But if I generate payload file separately, I need to integrate it in coreboot separately.

So I am checking if there is way to build the payload in coreboot itself.

Hello Mayuri,

You should check payload called: Tiano Core (true UEFI payload).

Hi

Is there any mechanism to build UEFI payload directly in coreboot similar like seabios?
