Xeon D BIOS hang when BIOS setting rst_cpl3

[vvinc3]

Now we debug Xeon D BIOS, the BIOS will hang when BIOS setting rst_cpl3(Register BIOS_RESET_CPL). If jump the bit set, BIOS will start-up, but my OS can't start-up. Can you give me any suggestion to debug the problem? Thanks.

Hi Vicent_0905,

Could you please provide the following?Processor model:Motherboard model:BIOS version: Regards,Hellen.

[vvinc3]

Processor model: D-1527

Motherboard model: Reference CRB CamebackMnt

BIOS version: BIOS come from my BIOS vendor Insyde. used RC code version is 1.9.5

we try to update RC code to 2.2.0 and Codebase to 05.05.15.0025, but the problem still exist.

The board is designed by ourselves, and D-1527 is used on the board. We manufacture 5pcs boards, two pcs boards can't start-up from BIOS, and two pcs boards can start-up from BIOS, but after few minutes, the console port hang, and can't input or output any information from CPU.

If disable the following feature(EIST, UFS, Turbo mode), the capable boot-up board will hang after starting up for few hours, maybe have some improvement.

I have tested the voltage, ripple and noise of some powers, and don't find any abnormal.

Dear vvinc_3

I am bios engineer.

I 'm having the same problem as you. The problem is exactly the same.

I made the 6 pcs sample board of alderlake. (bios is ami bios, process is i7-12700K)

3 pcs is booting well, but 3 pcs is stopped at BIOS_RESET_CPL.

I change the CPU, PCH and so on,,but the result is same.

Could you give me the hint for solution?
