We are developing coreboot for Apollo lake custom board. MRC training data is enabled in FSP using Binary configuration tool.
We are facing the following observations:
1. After flashing the first boot takes 10 sec to boot.
2. For next cold boot the boot time takes 6 sec and remains same.
So we dumped the flashed coreboot image and re-flashed the dumped coreboot image to the chip.
1. After flash the first boot takes 6 sec to boot.
2. For next cold boot also the same 6 sec is observed.
Could you please explain on the above observations ?
Can we extract the MRC training data and add it to the coreboot image ? If yes, could you please share the steps to be done ?
Thanks & Regards,
