ADL-S / PCH dose not working after SLP_A

hello

I am using the ALDER LAKE S platform. (PCH: R680E)

NON-DEEP setting and EC is not used.

The power sequence is all fine, and the SPI also operates for about 500 ms after the voltage is applied.

However, currently my board does not work after SLP_A#.

SLP_S5# is not set to 3.3V.

 

HW STRAP setting of PCH is as follows.

- MAF (GPP_H12 : LOW )

- Disable ESPI ( GPP_C5 : HIGH)

- VCCSPI : 3.3V ( GPP_H18 : LOW )

- BBS ( GPP_I22 : LOW)
