[U-Boot] uboot information

[Sébastien Basset]

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. 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, 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 ?

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

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?

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 at 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.

I thought you said it was MMC...do you mean it is a USB controller
with an USB->MMC device?

1/ No, As i am stuck on the mmc (pci controller internal soc),
2/ Now i try to boot on usb key, but i don't see controller usb
Sorry, these are two different problems.

It is better to post at the bottom that the top, for mailing lists.

I think PCI XHCI has some problems. I'm not sure of its status.

MMC seems to work well on Minnowboard Max (baytrail) but I am not sure
about braswell. Is it perhaps a slightly different chip?

For PCI XHCI, i see controller usb and root hub, but cannot reset port:

portstatus 711, change 0, 5 Gb/s
STAT_C_CONNECTION = 0 STAT_CONNECTION = 1  USB_PORT_STAT_ENABLE 0
portstatus 711, change 10, 5 Gb/s
STAT_C_CONNECTION = 0 STAT_CONNECTION = 1  USB_PORT_STAT_ENABLE 0
portstatus 711, change 10, 5 Gb/s
STAT_C_CONNECTION = 0 STAT_CONNECTION = 1  USB_PORT_STAT_ENABLE 0
portstatus 711, change 10, 5 Gb/s
STAT_C_CONNECTION = 0 STAT_CONNECTION = 1  USB_PORT_STAT_ENABLE 0
portstatus 711, change 10, 5 Gb/s
STAT_C_CONNECTION = 0 STAT_CONNECTION = 1  USB_PORT_STAT_ENABLE 0
Cannot enable port 10 after 5 retries, disabling port.
Maybe the USB cable is bad?
cannot reset port 10!?

do you have an idea,why reset port is break down ?

For MMC, braswell n3160 is dedicated for embedded iot, maybe for security.
