hi,
i see controller:
src/soc/intel/braswell/chip.c/enable_dev ( Intel Braswell SoC ), type: 2 vendor: 0x8086. device: 0x2296 class: 0x08 Generic system peripheral subclass: 0x05 SD Host controller prog: 0x01 revision: 0x35 src/soc/intel/braswell/southcluster.c/southcluster_enable_dev ( Intel Braswell SoC ) PCI: 00:12.0 [8086/2296] ops PCI: 00:12.0 [8086/2296] enabled
but i can't test sdcard in coreboot ...
i had intel back on this issue, on braswell 3160 version, it's not possible of boot on sdcard : It can be found on page 31 of the Braswell** Design In for The Internet of Things (IoT) document 555139.
it's very strange !!??
else i try to boot on usb:
I added node in dts file :
usb@14,0 { reg = <0x000a0000 0 0 0 0>; compatible = "xhci-pci"; };
is there another step for see controller with usb start command ?
Thank you for your information.

Hi,
Coreboot load uboot as payload.
Does the MMC work OK in coreboot?
It is possible to load U-Boot from UEFI if that helps?

Sorry for the inconvenience, i have problem for read mmc on my board with braswell cpu, i would like test on other board, i have nuc intel
with
braswell,is there possible when there is already bios to load uboot ?
else has any chance, I use coreboot + uboot, i would like run kernel
on
sdmmc, but i have an problem for communicate with sdcard. I read cid & reference of card but when try read SCR(version & bus width) of card, doesn't work . For read scr, it's first Transfer mode in SDMA .i had
no
error for read data but buffer is empty, why ?I use coreboot + uboot,

Just to be clear, are you running U-Boot on top of Coreboot?
