Slimbootloader MR8 FspDbg.bin Does NOT Produce Debug Information

[Siddhartha]

Hi.

We use an i7 processor on a custom circuit board based on UP Xtreme i11 Tiger Lake.

We were advised on the (groups.io/g/slimbootloader/) forum to use the latest (MR8) versions of Slimboot code & FSPDbg.bin.

So we obtained the MR8 folders for Slimboot after searching through Intel RDC.

We built MR8 Slimboot & stitched it using the following commands:

Build:

D:\SBL_TGL-UP3_MR8\SblPlatform>python SblBuild.py build tgl -fd -k -p "OsLoader.efi:LLDR:Lz4;UEFIPAYLOAD.fd:UEFI:Lzma"

Stitch:

D:\SBL_TGL-UP3_MR8\SblPlatform>cd SblOpen
D:\SBL_TGL-UP3_MR8\SblPlatform\SblOpen>python Platform\TigerlakeBoardPkg\Script\StitchIfwi.py -b legacy -p tglu_b0 -w D:\StitchingV -d 0xAA000004 -s Outputs\tgl\Stitch_Components.zip -c Platform\TigerlakeBoardPkg\Script\StitchIfwiConfig_tglu.py -o 32MB

Since we used -fd for build, we expected that:

    FspDbg.bin (of size 1696 KB with the following path) would produce debug information. 

    D:\SBL_TGL-UP3_MR8\SblPlatform\SblOpen\Silicon\TigerlakePkg\FspBin\FspDbg.bin

But we do NOT see debug information on the serial port.

1. Are our build & stitch commands right ?

    1.1. If so: Where can we get a working FsbDbg.bin for MR8 ?

    1.2. If NOT: What are the right build & stitch commands ?

Thanks.
