Hi Please see the following issue for reference. https://github.com/slimbootloader/slimbootloader/issues/525 Basically, first step is to review the memory settings and confirm that they match your HW configuration. To make sure your delta file is taking effect, you can add some debug statements where the FSP-M UPD configuration is updated. Next step is if you have directly Intel support, you can also request a DEBUG FSP binary from them to get more useful information to analyze the memory training failure.

The memory settings finalized, according to the board schematics. Unfortunately, the boot is hanging on the FspMemoryInit all the time. How can I understand why FspMemoryInit stuck. Can I make debugging inside ? I've tried to use LEAFHILD.X64.0071.D01.1809040132.bin and LEAFHILD.X64.0071.R01.1809030849.bin to stitch, both have the same output MMC is disconnected physically, an error in the output is ok Output: ============= Intel Slim Bootloader STAGE1A ============= SBID: SB_APLI ISVN: 001 IVER: 000.005.001.000.16526 SVER: 2A76A65FA31E58AC-dirty FDBG: BLD(D) FSP(R) FSPV: ID($APLFSP$) REV(01040301) Loader global data @ 0xFEF01C40 Run STAGE1A @ 0xFEF80000 Load STAGE1B @ 0xFEF88000 No BtGuard verification ! ============= Intel Slim Bootloader STAGE1B ============= CPU : APL-D0 [4C @ 1600MHz: premium SKU], uCode rev.2E Early GpioInit for EMMC MMC global data init Use SDMA instead of ADMA2 MMC Phase 1 init MmcGetOcr Fail Status = 0x80000007 Early MMC Init Fails @ 0xFE700000 - Status(Device Error) SpiInstance = FEF03340 PchSpiBase at 0x00000D02 ScSpiBar0 at 0xD2000000 Append public key hash into store: Unsupported Load EXT CFG Data @ 0xFEF03BE4:0x0DB4 ...
