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. 2017-03-22 14:05 GMT+01:00 Simon Glass <s...@chromium.org>: > Hi, > > On 18 March 2017 at 02:25, Sébastien Basset <sbas...@aviwest.com> wrote: > > 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? > > - Simon > > > > > Le 17 mars 2017 19:14, "Simon Glass" <s...@chromium.org> a écrit : > >> > >> +Bin > >> > >> Hi Sebastian, > >> > >> On 17 March 2017 at 11:23, Sébastien Basset <sbas...@aviwest.com> > wrote: > >> > > >> > Hello, > >> > > >> > 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.
