IMX6Q -PCIE+i210 ethernet controller in u-boot

[agnel_terry]

HI ,

I have accustom hardware uses IMX6q which has a intel i210 ethernet controller connected to PCIE of IMX6Q , I had configured the PCIE in Kernel and enabled the e1000 driver , I am able to enumerate the controller ping works fine, etc.

whereas when I try to configure the controller and PCIE in UBoot, I see PCI driver listing the devices but the ethernet controller is not seen in the "NET:" looks like the e1000 driver is not getting linked to built-in.o

Can someone help me with the correct configuration of the uboot for PCIE and e1000. (I am not using driver model, I am configuring my 2017 in the legacy way.

Below is my Uboot log

HI Terry

for the i210 in defconfig

CONFIG_NET_VENDOR_INTEL=y

CONFIG_IGB=y
CONFIG_IGB_HWMON=y

lspci

   04:00.0 Ethernet controller: Intel Corporation I210 Gigabit Network Connection (rev 03)

I am also fighting the iMX6q with i210 and XR17V358 - The PCIe works on some PCBs work and not on other PCBs

Regards

Mike

Hi Terry

one can check ifdef CONFIG_PCI in uboot/include/configs/mx6sabresd.h

and test several cards

mx6sabresd.h\configs\include - uboot-imx - i.MX U-Boot 

Best regards
igor

Hi Igor,

Thank you for the response, the problem is not on the PCI/PCIE layer, as mentioned I am able to see the device getting listed in the PCI:

PCI:
  00:01.0     - 16c3:abcd - Bridge device
   01:00.0    - 8086:1533 - Network controller

whereas its not seen in the NET :, The net shows only the IMX6 FEC, I had added "CONFIG_E1000=y" for the ethernet controller driver, still I don't see the device getting listed under,NET.

Thanks

Terry

Hi Terry

as this is not specific imx issue this may be posted on uboot mail list

Thank you Igor, will post it in the u-boot info page
