Hello Mr.BIn,
I tested using the latest u-boot (u-boot-2016.07-rc1) with CONFIG_GENERATE_ACPI_TABLE=y enabled. I am still facing the same issue, the Linux kernel is not able to initialize the root file system from the sd card. I have attached the logs for your reference.
My Analysis: [ 1.267312] sdhci-pci 0000:00:12.0: failed to setup card detect gpio -- this error message I am seeing with UEFI firmware also. So I am assuming it is not the issue here.
I have done some debugging of MMC initialisation and found that in mmc_rescan function (drivers/mmc/core/core.c)
host->ops->get_cd(host) returns 0
and the condition is failed. So MMC is not getting intialized. i checked the return of
!!(sdhci_readl(host, SDHCI_PRESENT_STATE) & SDHCI_CARD_PRESENT); and here I am seeing that
with U-boot version it is 1FA0000 and bit AND with 0x00010000 is zero (condition fails) with UEFI version it is 1FF0000 and bit AND with 0x00010000 is one (condition succeeded)
Do you have any idea why this is happening, any input from your side will help me
Issue identified. Working on a fix. Stay tuned.
Thanks a lot:)
