Bring up Ethernet 1 (eqos) in imx8mp evaluation kit

[Adi99]

Hello,

I am working with imx8mp evolution kit with Android 11 OS.

I want to work with Both On board Ethernet (eth0 and eth1)

By default eth0 which is fec controller is working fine, we are able to see the Eth0 node by ifconfig and we are able to ping.

But i am not able to bring up the Eth1 which is eqos node in imx8mp-evk.dts

Please suggest some solution to bring up the Ethernet 1[eqos node] in imx8mp evalution kit.

Below is the device tree node for eqos node:

&eqos {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_eqos>;
phy-mode = "rgmii-id";
phy-handle = <&ethphy0>;
status = "okay";

mdio {
compatible = "snps,dwmac-mdio";
#address-cells = <1>;
#size-cells = <0>;

ethphy0: ethernet-phy@1 {
compatible = "ethernet-phy-ieee802.3-c22";
reg = <1>;
eee-broken-1000t;
rtl821x,aldps-disable;
rtl821x,clkout-disable;
};
};
};

Thanks in Advance.

Thanks for your help!   But I could not find the patch and gz file discribed in  document.  Would you send me the two file?

[Adi99]

hello,

sorry for the late response.

--->You don't need remove ko path with GKI. The GKI will compile all drivers into ko.You need let the compile system move these driver into rootfs

>>>  i am using gki kernel. with that we arenot able to build phylink.ko file

can elaborate more to enable eqos node in imx8mp 

what are the changes in gki fragment - defconfig and kernel device tree file?

[Zhiming_Liu]

Send you the document

[Miles_x]

I am trying to do the same thing with android 12.0.0_1.0.0 on the 8mp evk.  Could you please provide the document you mentioned above to me, Thanks!

[mark_vogt]

I am trying to do the same thing with android 13 on the 8mp evk.  Can you please provide the document you mentioned above?

[Adi99]

@Zhiming_Liu will provide the document.

[Adi99]

Hello ,

Thanks for quick response.

The Document you shared which contain aosp source code version Android-11.0.0_2.0.0 and my version of aosp source is Android-11.0.0_2.6.0.

As per the Document we need to add kernel configuration to android_gki_defconfig (android_build/device/nxp/imx8m/evk_8mp). But in version "Android-11.0.0_2.6.0" "android_addition_defconfig" is there.

So, i put all kenel configuration to "android_gki_defconfig" at "android_build/device/nxp/imx8m/evk_8mp"

Below kernel configuration we added in "android_gki_defconfig":

CONFIG_STMMAC_ETH=m
CONFIG_STMMAC_PLATFORM=m
CONFIG_DWMAC_IMX8=m
CONFIG_PHYLINK=m
CONFIG_REALTEK_PHY=m

and Addded Below info to SharedBoardConfig.mk :

$(KERNEL_OUT)/drivers/net/phy/phylink.ko \
$(KERNEL_OUT)/drivers/net/pcs/pcs-xpcs.ko \
$(KERNEL_OUT)/drivers/net/ethernet/stmicro/stmmac/dwmac-imx.ko \
$(KERNEL_OUT)/drivers/net/ethernet/stmicro/stmmac/stmmac-platform.ko \
$(KERNEL_OUT)/drivers/net/ethernet/stmicro/stmmac/stmmac.ko

Other Changes also i have done as per document.

But i am facing Below error while compiling:

FAILED: ninja: 'out/target/product/evk_8mp/obj/KERNEL_OBJ/drivers/net/phy/phylink.ko', needed by 'out/target/product/evk_8mp/obj/PACKAGING/depmod_vendor_stripped_intermediates/phylink.ko', missing and no known rule to make it
16:20:42 ninja failed with: exit status 1

I am not able to get phylink.ko in out folder

Thanks

[Zhiming_Liu]

The Android we release will output No-GKI boot image as well(name:boot-imx.img), you can add configs to android_addition_defconfig and download boot-imx.img

[kevincheng]

Hi,

We have the same problem in Android 13 on iMX8mp. How to use No-GKI mode and use boot-imx.img to replace boot.img ??

[Adi99]

Hello,

I add the configuration to android_addition_defconfig 

i am facing this error while compiling.

FAILED: ninja: 'out/target/product/evk_8mp/obj/KERNEL_OBJ/drivers/net/phy/phylink.ko', needed by 'out/target/product/evk_8mp/obj/PACKAGING/depmod_vendor_stripped_intermediates/phylink.ko', missing and no known rule to make it
16:20:42 ninja failed with: exit status 1

Thanks

[Zhiming_Liu]

1.No-GKI kernel

Set these CONFIG to y, you don't need add the ko in SharedBoardConfig.mk

2.GKI kernel

add these configs to android_build/vendor/nxp-opensource/kernel_imx/arch/arm64/configs/imx8mp_gki.fragment

[Adi99]

Hello,

Thanks for quick response,

I updated the configs in "android_build/vendor/nxp-opensource/kernel_imx/arch/arm64/configs/imx8mp_gki.fragment" 

and  I removed the KO path from SharedBoardConfig.mk.

but it didn't works,

I am attaching the snapshot of configs which I am adding in imx8mp_gki.fragment 

And, Any changes require in u-boot.

Thanks,

[Zhiming_Liu]

I updated the configs in "android_build/vendor/nxp-opensource/kernel_imx/arch/arm64/configs/imx8mp_gki.fragment" 

and  I removed the KO path from SharedBoardConfig.mk.

--->You don't need remove ko path with GKI. The GKI will compile all drivers into ko.You need let the compile system move these driver into rootfs.

[Adi99]

Once I try I will update you.
