J7200XSOMXEVM: Ethernet communication is not working properly

user4852186
Intellectual 340 points
Part Number: J7200XSOMXEVM
Other Parts Discussed in Thread: DRA821

Tool/software:

Hi Team,

I am checking the communication in the following environment.

EVM：J7200XSOMXEVM + J721EXCP01EVM
SDK：PROCESSOR-SDK-LINUX-RT-J7200
VER：09.01.00.07
BOOT Image：prebuilt-images内のtiboot3.bin，tispl.bin，u-boot.img
DeviceTree：k3-j7200-common-proc-board.dtb
FileSystem：tisdk-default-image-j7200-evm

I am experiencing the following issue with the Ethernet port (MCU_RGMII1) on connector J35 of the EVM. Could you please give me some advice on how to resolve this issue?

  • When the communication speed is set to 1000Mbps, communication is not possible.

In both u-boot and Linux, the IP address was not automatically obtained via DHCP at 1000Mbps, but it was obtained automatically when set to 100Mbps.

Also, when I set a static IP address, there was no response to PING.

  • When the communication speed is set to 100Mbps, communication is possible but not stable (frequent CRC errors occur).

When TFTP communication was performed at 100Mbps in u-boot, a timeout occurred.

I want to achieve a stable communication speed of 1000mbps (without CRC errors). Can you tell me what I should do to achieve this?

Also, please tell me about coprocessors settings.

In the case of prebuilt-images, I think that the CPSW2g driver will be enabled for MCU_RGMII1.
In that case, would it be okay to disable the coprocessors (main-R5F, mcu-R5F) as follows?

&main_r5fss0_core0{
	status = "disabled";
};
&main_r5fss0_core1{
	status = "disabled";
};
&mcu_r5fss0_core0{
	status = "disabled";
};
&mcu_r5fss0_core1{
	status = "disabled";
};

    Hi,

    All of these are CRC errors could point to some issues with the link.

    So one end of the link is the MCU_RGMII port of the EVM. What is the other end connected to?

    Are you seeing the same results even if you change the EVM?

    Hi,

    The network configuration is shown below.

    We only have one J7200XSOMXEVM , so we can't check it on another J7200XSOMXEVM .

    However, when I checked communication with AM68-SK on the same network, it worked normally.

    Hi,

    I wrote a similar code based on the AM68-SK device tree, and was able to communicate normally on Linux.

    &davinci_mdio {
    phy0: ethernet-phy@0 {
        reg = <0>;
        ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_00_NS>;
        ti,fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>;
+       ti,min-output-impedance;
    };
};

    Are there any problems with the modifications?

    I also made similar modifications to the "u-boot" device tree, but this did not improve the situation.

    What do I need to fix to communicate properly in '"u-boot"?

    Regards,

    Mizutani

    Hi Mizutani-san,

    Sorry for the delay.

    Can you check the value of rx-checksum-offload by defalult. Can you see if toggling that changes anything?

    To see the current value : ethtool -k eth0

    To change it : ethtool -K eth0 on/off

    If the current value is on, can you please try with on and vice-versa.

    This issue was resolved by making the following change: Is this the correct change?

    1. device tree file (k3-j7200-common-proc-board.dts)

    &davinci_mdio {
    phy0: ethernet-phy@0 {
        reg = <0>;
        ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_00_NS>;
        ti,fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>;
+       ti,min-output-impedance;
    };
};

    2. u-boot config file (j7200_evm_a72_defconfig)

    Add "CONFIG_PHY_TI_DP83867"
    By making the above modifications, I was able to communicate at 1000Mbps in both u-boot and linux.
    Also, when I was investigating the cause, I checked the Ethernet interrupts, but I didn't understand the contents of the following interrupts. Could you please tell me the contents of each interrupt and where to set it?

    Hi Mizutani-san,

    user4852186 said:

    I don't see issue with the change. It changes some configuration in the phy which is ususally not required for the DP83867 phy (the RGMII phy used on EVM), but is used with other TI phy's in some cases. I do not know how this exactly affects the phy. I'll find that out and let you know by next week.

    So there are in total 8 tx dma channels and 1 rx dma channel for data transfer with ethernet. There is one interrupt for each DMA channel. Thats the interrupt you see in the output of "cat /proc/interrupts".

    user4852186 said:

    Can you please elaborate on the modifications needed for interrupts. Do you want to change irq number or something different?

    Hi,

    In the Jacinto7 DRA821 Evaluation Module (EVM) User's Guide, the PHY used in the J7200 is DP83867. Is this correct?

    Regarding interrupts, I would like to mask unnecessary interrupts.
    Therefore, I would like to know the details of each interrupt. Also, could you tell me how to set the interrupt mask?

    Mizutani

    Yes, This is correct.

    You will only have the interrupts for those channels (queues) which you have enabled. It seems you have enabled all 8 queues. You can change the number of interrupts by opening lesser number of queues.

    You can change number of queues by running "ethtool -L <dev name> tx <no of queues>"

    This changes the "IO_IMPEDANCE_CTRL" property in "I/O Configuration (IO_MUX_CFG), Address 0x0170" register of the phy (phy datasheet).

    This means that there might some issue with a resistor on the EVM. This has to be investigated separately. Please create a ticket if you want to investigate the hardware issue.

    Hi,

    Please explain again about "changing some configurations of PHY that are not usually necessary for DP83867 PHY (RGMII PHY used in EVM)".
    The PHY used in J7200 is DP83867, so why not use CONFIG_PHY_TI_DP83867 (dp83867.o)?

    Also, please tell me about interrupts.
    If the number of channels is set to 2, will each channel be assigned to a CPU as follows?
    ethernet-tx0:CPU0
    ethernet-tx1:CPU1

    This is configurable. you can attach the interrupts to one core or both cores as well. See this for more details on configuration.

    The phy driver (dp83867.o) is being used to configure the phy. On EVM, it seems that you have to add "ti,min-output-impedance;" property to make the phy work. This is not the case on other EVMs. Hence there might be some issue with the board you have. Hence my suggestion to investigate that separately if required. If you are just going to use EVM for testing and going to design your own board, then you can continue like this with "ti,min-output-impedance;" property.
