Hi,
We are developing coreboot (with Intel FSP) for apollo lake platform custom board. We are facing a hang issue during the SYS_RESET button press.
Observations:
* With soft reset the board gets hang(occurs within 2 or 3 reboot) with POST code 0x38 and the coreboot log stops during the romstage relocation. (Logs attached for Ref.) * When the SYS_RESET is pressed again the board boots and hangs at same POST code 0x38.
Please provide feedback and help us to resolve this issue.
Currently our coreboot build does not include any microcode (CPU_MICROCODE_CBFS_NONE). We tried to change it as "Generate from tree" in memuconfig. But the build fails with fatal error saying no microcode/microcode.h file.
Whether the CPU by default have microcode ? or we need to build the microcode in coreboot ? Please advise on this.
Thanks & Regards, Antony
