AR8035 on am335x custom board with sdk8

To supply:

If I set Ip manually ifconfig eth1 192.168.30.1 netmask 255.255.255.0 , then connect to computer directly, It still can't ping each other.

Hi Bernie,

How many Ethernet ports do you have on your board? Please note that if you have 2, then they must be connected to different network segments.

Hi Biser
1 ethernet wan port & 4 switch LAN ports.

Hi Biser

SDK8 kernel config has default configs built in for dual emac

[*] Texas Instruments (TI) devices │ │
│ │ -*- TI DaVinci MDIO Support │ │
│ │ -*- TI DaVinci CPDMA Support │ │
│ │ -*- TI CPSW Switch Phy sel Support │ │
│ │ <*> TI CPSW Switch Support │ │
│ │ [*] TI Common Platform Time Sync (CPTS) Support

and DTS file has default "dual_emac = <1>"

&mac {
651 » pinctrl-names = "default", "sleep";
652 » pinctrl-0 = <&cpsw_default>;
653 » pinctrl-1 = <&cpsw_sleep>;
654 » dual_emac = <1>;
655 };

and there are my boot message below

cpsw 4a100000.ethernet: Detected MACID = d0:39:72:4d:53:4b
[ 3.052133] cpsw 4a100000.ethernet: cpsw: Detected MACID = d0:39:72:4d:53:4d

And I doubt am33xx.dtsi: "active_slave=<0>" should be active_slave=<1>?

mac: ethernet@4a100000 {
683 » » » compatible = "ti,cpsw";
684 » » » ti,hwmods = "cpgmac0";
685 » » » clocks = <&cpsw_125mhz_gclk>, <&cpsw_cpts_rft_clk>;
686 » » » clock-names = "fck", "cpts";
687 » » » cpdma_channels = <8>;
688 » » » ale_entries = <1024>;
689 » » » bd_ram_size = <0x2000>;
690 » » » no_bd_ram = <0>;
691 » » » rx_descs = <64>;
692 » » » mac_control = <0x20>;
693 » » » slaves = <2>;
694 » » » active_slave = <0>;


Thank you.

Hello

I attache my boot log with ubuntu 14.04 , hope somebody give me suggestions.......maybe some wrong message cause ethernet problem.
Thank you very much

Welcome to Ubuntu 14.04 LTS (GNU/Linux 3.14.26-g2d3247c-dirty armv7l)

There is a file in kernel : arch/arm/mach-imx/mach-imx6q.c, I found they have some information about AR8031 TX delay, I don't know why AR8035 don't need it, but my patch of sdk6 have done , then where I can do these fix up in sdk 8? I will appreciate that you give me a hand.

Hi Bernie Chen,

I am in a similar situation although I believe the fixup has been moved to the phy driver in linux. I believe the fixup is in at803x.c in /drivers/net/phy/at803x.c Line: 180

I can get gigabit working at sub-optimal performance by changing the phy-mode in am335x device tree. The phy-mode is rgmii-txid but when changed to rgmii it appears to work (Although I should clarify that this does not seem to be the correct phy mode). Although the performance is horrible.
When using iperf. The transmission is approximate 32Mbit/s and Receiving is approximately 90Mbit/s.

I have tested the same board on Linux 3.2 and able to get transmission of 280Mbit/s and receving of 320Mbit/s.

Could a TI Member please clarify what the issue may be with this?

EDIT:
Although even being in RGMII (no TXID) mode wouldn't explain the poor performance when receiving data. So I am guessing a clock division has gone wrong in am335x-clocks.dtsi. I remember reading a post in regards to this issue that relates with CORE_CLOCKOUTM5. But I could be completely wrong

Hi Tyson Thomas

Sorry. Indeed, my AR8035 has been not worked yet. Just like you see. And could you attach your patch about device tree file for us if you don't mind? Thank you.

Hi Bernie,

Sorry for the late reply.

If you open your kernel's source and go to /arch/arm/boot/dts and open (I'm going to assume your board is based on EVM). Modify the &cpsw_emac0 node in am335x-evm.dts. It will state the phy-id and phy-mode.
Change it to:
phy_id = <&davinci_mdio>, <7>; /*Your phy id that I saw in your boot log*/
phy-mode = "rgmii"; /*phy mode, strangely ours works without txid*/

I don't believe rgmii is the right mode but as of today I have sort of resolved my performance issues and have not changed back to rgmii-txid.

Dear Tyson

Excuse me, which version of TISDK you are using?

Dear Tyson

Do you have checked this thread?
www.deyisupport.com/.../203718.aspx

This is problem about your RX TX speed with internal delay bit of GMII_SEL.

By the way, I still try to find the problem why I can't get IP address with my AR8035

Hi Bernie,

So in regards to my problem, I have managed to solve it by reconfiguring my kernel which was strange solution as I can't for the life of me figure out what I configured that caused this issue. I can confirm that my phy-mode is still on RGMII (Not RGMII-TXID) and I am getting the speeds shown on the TI Ethernet performance wiki (approximately 280Mbit/s up, 360Mbit/s down).

I tested this on both SDK8 and SDK1.003 (Latest) as well as with mainline kernel from github.

Thank you for your help I can only hope my assistance has helped you solve your problem.

I'll take an excerpt from my DTS file in /arch/arm/boot/dts/am335x-evmsk.dts

So if you look at (Which is the default from am335x-evmsk.dts):

&cpsw_emac0 {
    phy_id = <&davinci_mdio>, <0>;
    phy-mode = "rgmii-txid";
    dual_emac_res_vlan = <1>;
};

The changes you will need to do are:

&cpsw_emac0 {
    phy_id = <&davinci_mdio>, <7>; /* This reflects the id that I saw in your bootlog */
    phy-mode = "rgmii"; /* This has enabled gigabit ethernet for me */
    dual_emac_res_vlan = <1>;
};

Although I am using the am335x-evmsk as an example you could be basing your custom board off that device tree. If not I would look into what dtb file that uboot is loading or what dtb file that is being appended to your kernel.

Hi Tyson

Thanks your sharing and I want to know your AR8035 that is on slave1 or slave2 ?

Thank you. 

Dear Tyson

May I check your value of gmii_sel register? plz make "devmem2 0x44e10650", Thank you very much..

 

Dear chen,
Are you success now? I have the same problem, the eth1 can see ,but cannot ping.

Dear chen,

Plese reply me ,or send a email at 465226464@qq.com. Thanks a lot.

Hi
sdk8 u-boot initialize core volutage and MPU frequency to opp50, so you have no function of ethernet
