P4080ds cannot find eth0 interface

peterzheng · ‎01-27-2015

Hello,

I am trying to set up the DHCP ethernet connection of my p4080ds board. I am using the core image. I use a switch to connect host system and my board.

After boot up, the board alerts the following message:

WARNING: adjusting available memory to 30000000
Wrong Image Format for bootm command
ERROR: can't get kernel image!

So I use "pix altbank" to boot up in alternative bank. After I enter the system, I type ifconfig. But it seems there is no eth0 interface.

root@p4080ds:~# ifconfig -a

Hello Peter,

Please refer to "3.2.23.2.3.1.4 SerDes Protocol 0xe, P4080 Rev 2, Total Capacity 23 Gbps" in SDK document, please check whether the physical network connection is correct, then configure IP address for "fm*-gb*".

Thanks,

Yiping

Hello Peter,

On P4080DS Linux System, Ethernet ports on PCIe Network interface (XAUI) card are name as eth* interface.

Thanks,

Hi Yiping,

Do you know how could I set up the internet to make P4080DS connect to internet?

Regards,

Peter

Hello Peter,

On DPAA(including P4080DS) target board, we don't use eth* naming convention, we use fm*-gb* in Linux Kernel instead, which means the ethernet ports connecting to FMAN, please refer to the following port mapping for the RCW which you are use on this bank.

U-boot Port i Linux FMAN Address

FM1@DTSEC2 fm1-gb1 0xffe4e2000

FM1@TGEC1 fm1-10g 0xffe4f0000

FM2@DTSEC3 fm2-gb2 0xffe5e4000

FM2@DTSEC4 fm2-gb3 0xffe5e6000

FM2@TGEC1 fm2-10g 0xffe5f0000

You could get detailed information in p4080ds.dts,

fman0: fman@400000 {

... ...

enet1: ethernet@e2000 {

tbi-handle = <&tbi1>;

phy-handle = <&phy1>;

phy-connection-type = "sgmii";

};

... ...

enet4: ethernet@f0000 {

phy-handle = <&phy10>;

phy-connection-type = "xgmii";

};

}

fman1: fman@500000 {

... ...

enet7: ethernet@e4000 {

tbi-handle = <&tbi7>;

phy-handle = <&phy7>;

phy-connection-type = "sgmii";

};

	enet8:ethernet@e6000 {
	tbi-handle = <&tbi8>;
	phy-handle = <&phy8>;
	phy-connection-type = "sgmii";
	};

	enet9: ethernet@f0000 {
	phy-handle = <&phy11>;
	phy-connection-type = "xgmii";
	}; }

Have a great day,
Yiping
