Hi, Dne 25. 10. 18 v 9:17 Zheng Bao napsal(a): > Any more ideas? Thanks. Maybe the bus topology is different in coreboot. It would explain why SATA works, because it is on bus 0. Thanks, Rudolf -- coreboot mailing list: coreboot@coreboot.org

Re: [coreboot] Hardware diagnostic

I suggest you better check 1. power on sequence, 2. every power/ voltage rail stability during boot process. 3. Over/undershoot. 4. all crystal osc frequency stability during boot process. 5. Try to print the DID early during bootblock and romstage. Provide your observations. Regards, Naresh G
