Thinkpad X1 C7 Comet Lake gets stuck right after clover selection

[bomdurup]

Hello!

Thinkpad X1 Carbon 7th (C7) Model 20R1 did not allow me to boot with Clover, neither the OpenCore.

This laptop has i7-10510u 10th Gen Comet Lake , LPDDR3 16GB Ram onboard and intel UHD 620 iGPU.

BIOS is quite limited so I could only disable Thunderbolt3, VT-d, Secureboot, kernal DMA protection. There were no options like XHCI Hand-off, 4G Encoding and so on.

 

 

 

Things I've tried : 

*Olarila's Clover EFI (for laptop skylake+) - Screen goes black right after boot option selection and hangs there

*Olarila's OC EFI (for laptop skylake+) - Can't see options except [Reset NVRAM] on opencore selection, so changed scanpolicy to 0 on config.plist - Screen goes black right after boot option selection and hangs there!

to see what happend, I swapped opencore.efi / bootx64.efi to official release of opencore 0.5.7 (debug version), change display level to 2147483714, target to 67 to get full log.

driver fwruntimeservices.efi was replaced to Openruntime.efi with official opencore 0.5.7 so I did that too.

 

The log (after boot option selection on opencore) is as follows : 

227:424 00:105 OCB: Perform boot Install macOS Catalina to dp PciRoot(0x0)/Pci(0x14,0x0)/USB(0xF,0x0)/HD(2,MBR,0xD5D90FC8,0xA76800,0x122D000)/\System\Library\CoreServices\boot.efi (0/0)

if I change revirtualizemmio to True, there will be two more lines added like this

160:183 00:087 OCABC: MMIO devirt end, saved 0 KB

 

 

 

I've tried other EFIs and configs from comet lake processors like these but non of these worked. The result is always the same. (some clover EFIs will show +++++++++++++++++++)

Tried making SSDT-PLUG and HPET from my dumped DSDT but same result.

Lilu and WEG were replaced to latest version claims to be suppporting new processors.

 

Am I missing something?

Thanks MaLd0n.

I've just tried with EFI you gave me. Same, I got stuck at black screen right after selecting Boot option.

(USB stick was okay since it works on other desktop - boots to installer.)

 

+ I've made a memmap of this laptop from UEFI shell and it was okay, 1.7GB space for 0x100000. 

 

Is there any other option?

 

[bomdurup]

This is dumped DSDT.aml and no fix applied, memmap, and log from debug version of OC 0.5.7 I tried before

I changed your EFI to make logs - changed opencore to debug version, displaylevel 2147483714, target to 83, disablewatchdog to true.

 

this is the log from your EFI

I have a similar problem. My model is a ThinkPad X1 Yoga 4th Gen with i7 10710U. I solved the black screen issue by modifying the install EFI in this repository, but now it's stuck here:
