AM6422: linux ICSSG0 MII

Hello,

Which processor core is controlling the PRU Ethernet? What OS is running on that processor core?

Regards,

Nick

Wait, I see that you specified Linux controlling the interface. It would still be helpful to hear what version of the SDK you are running.

You can get started by referring to the Linux SDK docs here: https://software-dl.ti.com/processor-sdk-linux/esd/AM64X/09_02_01_09/exports/docs/linux/Foundational_Components/PRU-ICSS/Linux_Drivers/PRU_ICSSG_Ethernet.html

Specifically, you can find information about selecting the MII version of the devicetree file here:
https://software-dl.ti.com/processor-sdk-linux/esd/AM64X/09_02_01_09/exports/docs/linux/Foundational_Components/PRU-ICSS/Linux_Drivers/PRU_ICSSG_Ethernet.html#mii-support

I would refer to the dualemac-mii version of the devicetree file for guidance on setting up an MII interface in the Linux devicetree file.

Regards,

Nick

Hi，

The version I use is 8.06.Currently, there are three network ports on our hardware, two CPSWs and one MII interface emac0 of ICSSG0. How should the device tree be modified in this case? The original device tree file only defines two Ethernets. If I use three Ethernets, what should I add directly to the device tree? Can you provide an example? Thank you very much！

Hello,

Is the existing AM64x Linux devicetree files not enough of an example for you? The AM64x EVM has 3 ports, and you can set them to either be 2 CPSW & 1 ICSSG, or 1 CPSW and 2 ICSSG.

Those files are at arch/arm64/boot/dts/ti/k3-am64*

Regards,

Nick

Hi，

I added the Ethernet of ICSSG0 to the device tree according to some suggestions from the forum. Now the Ethernet can be recognized, but ping is not possible. I have uploaded the device tree file. Please help me analyze it. 

I currently have 3 network ports, 2 CPSW, and one is the EMAC0 of ICSSG0. The interface with PHY is the MII interface. The Ethernet can be recognized by plugging and unplugging the network cable. Through the ifconfig command，At this time, the IP address has not been set yet, just connect the network cable to the computer, and then there will be data received。

eth2: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 metric 1

When I set the IP address and use the ping command, the following information appears

Hello,

What kind of terminal output do you see earlier in the initialization process? I would like to see the output from when the Linux driver initializes the PRU cores, the PHY, etc to see if there are any errors, warnings, or other helpful information.

Regards,

Nick

Hi,

Let me introduce my hardware first. The Ethernet part requires 1 and 2 ports of CPSW , icssg0 emac1, and does not use emac2. The PHY model is DP83620, and the interface mode is MII. I encountered a situation before where CPSW eth0 could recognize the connection, but ping was unsuccessful. By adding the two CPSW ports in the device tree file under the uboot path, both ports can work normally.But at this time, the network port of icssg0 is no longer recognized。I do not know why? I can make it work by modifying the device tree in the kernel, why do I need to change the device tree file in uboot?

When I add the same icssg0 related devices in the kernel to the device tree file in uboot, an error is reported，like icssg0_eth can not found ，icssg0_emac0 can not found ，icssg0_mdio can not found。

Hi,

I found a problem. In the last reply, the device tree file in uboot was modified, which caused ICSSG to be unrecognizable. I directly updated the default image and overwrite the dtb file compiled after the kernel configured ICSSG device tree to the SD card. Now ETH2 Ethernet can be recognized, but ping is unavailable. The following is my startup information, and the corresponding operation information is also below. Please help analyze it. Thank you！

Hi，

I saw this part in the document. This part needs to be entered under the uboot command line. Is there any information that can be printed out after entering it? Regarding the k3-am642-evm-icssg1-dualemac-mii.dtbo file, if we are using ICSSG0, where should this file be?Could you explain it in more detail?

Hi,

Is there any progress?Our project is waiting for the problem to be solved.

Hello,

I apologize for the delayed responses here. I was going to try to dig into your thread today, but it is already bedtime and I have to sign off. I will try to have a response for you in the next day or so.

Regards,

Nick

Hello,

Is there any progress?

Hi，

Still no news?We are eager to locate the problem quickly！

Hello Wanglili,

I apologize for the continued delays. This is another bedtime response, so no updates yet :(

Are there any new ideas?

Hi，

Is there any update? There is no solution to this problem in the forum. Can you give a complete operation guide for using the ICSSG0 Ethernet MII interface? We are very urgent.

Hello Wanglili,

Apologies for the delays to responses here. Understood that you are looking for a near-term solution.

There were some issues with MII operation on the Linux kernel 6.1 releases (as discussed in this other thread: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1314903/am6442-icssg0-mii-doesn-t-work-in-sdk9-1-0-8 ).

Just to confirm, are you still using SDK 8.6? (i.e., Linux kernel 5.10)

Regards,

Nick

Hi,

Yes, we are still planning to use version 8.6.

Hello Wanglili,

AM64x PRU Ethernet in uboot?

we do not support PRU Ethernet in u-boot on AM64x SDK 8.6. We added support for AM64x PRU Ethernet in u-boot starting in SDK 9.2.1, as mentioned in this FAQ: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1325243/faq-am6548-how-to-get-pru-ethernet-working-in-u-boot-on-am65x-linux-sdk-9-1

So I would expect that adding the PRU Ethernet nodes to the uboot devicetree file would not do anything.

Other notes from looking at your boot log - optimizing your DDR usage

[    7.155776] platform 78000000.r5f: configured R5F for remoteproc mode
[    7.155899] k3_r5_rproc bus@f4000:r5fss@78000000: split-mode not permitted, force configuring for single-cpu mode

AM6422 has two R5F subsystems, where each subsystem has only a single R5F core (as compared to AM644x, where each subsystem has 2 R5F cores). This terminal output confirms that there is only a single R5F core per subsystem, since the subsystem is getting set to single-cpu mode by the R5F driver.

That means that you can free up the DDR memory regions in your devicetree file that are allocated for the R5F cores that do not exist on AM6422. Please refer to the AM64x academy, multicore module, page "How to disable remote cores": https://dev.ti.com/tirex/explore/node?a=7qm9DIS__LATEST&node=A__Af8fKrelrD3vCdWjTx7.ww__AM64-ACADEMY__WI1KRXP__LATEST

if you have followup questions on disabling unused remote cores, feel free to create a new thread to discuss.

I'll provide another response soon.

Regards,

Nick

Hello Wanglili,

Ok so what about the MII interface? 

You are able to get a link up, so the PHY is able to autonegotiate with another PHY.

And your receive path looks good, since you are able to receive packets and you don't have any receive errors:

ethtool -S eth2
NIC statistics:
rx_good_frames: 208
rx_broadcast_frames: 38
rx_multicast_frames: 208
rx_crc_error_frames: 0
rx_mii_error_frames: 0

We need to figure out what is going on with the transmit path.

One potential cause of the issue is if the TX clock signal is not coming from the PHY to the MAC, then the transmit packets will just pile up and eventually the driver will timeout. Please take an oscilloscope and see if you are seeing a clock signal on the TX clock line.

Pinmux notes 

I don't see this getting pinmuxed: PRG0_PRU0_GPO8.PR0_MII0_RXLINK.It looks like this signal just goes to an LED on the PHY for the EVM, so I expect this would not be causing you problems.

It also looks like you are pinmuxing for both slice 0 (PRU0, RTU0, & TX_PRU0 drive one Ethernet interface) and slice 1 (PRU1, RTU1, & TX_PRU1 can drive another Ethernet interface), though you only have one Ethernet interface enabled in your devicetree file. Is that intentional?

Everything else looks good to me.

Regards,

Nick

Hi，

When I use the R5F core, the corresponding Ethernet can work normally and the TX clock signal is also available.Does this mean that there is no problem with this clock signal in the Linux environment? I will use an oscilloscope to look at the signal later.

PRG0_PRU0_GPO8.PR0_MII0_RXLINK I did not add his definition, I can add it later, I think you are right, this part is not the reason that affects Ethernet.

 slice 0 and slice 1 I have defined them in the device tree, but only 0 is actually used, I will modify it later.

I saw this part in the document. This part needs to be entered under the uboot command line. Is there any information that can be printed out after entering it? Regarding the k3-am642-evm-icssg1-dualemac-mii.dtbo file, if we are using ICSSG0, where should this file be?Could you explain it in more detail?

We use SDK8.06,Is there any related operation required?

Hello Wanglili,

That is interesting that you are able to control the PRU Ethernet interface from the R5F and it works just fine. I look forward to hearing about whether you see a clock signal in the Linux context (and if that is any different from what you observe from the R5F context).

I do not expect that you would need to apply a devicetree overlay file in uboot. That devicetree overlay file is only needed to modify the base evm.dts file so that the Ethernet interfaces are configured to be MII (since they are configured to be RGMII in the base evm.dts file - the AM64x EVM is shipped with PHYs that can be configured to run as either RGMII or MII).

However, for your usecase you have already written your MII settings directly into your board-level .dts file. I would not expect you to need to run additional uboot commands.

Regards,

Nick

Hi，

Due to other reasons, I have not used an oscilloscope to test the tx clock signal. I found an error in the startup print information. I am not sure whether this error is related to icssg.

also I change the R5F subsystems ，I am not sure if this is correct, can you help confirm it? The AM6422 chip used has a configuration of 2 R5F single cores。

Hello Wanglili,

"Unsupported resource 5" is expected, and should not have an impact on the internet.

The R5F changes look good to me.

I am not very familiar with the internal delay settings - let me check with some team members. Feel free to ping the thread if I have not replied by Thursday.

Regards,

Nick

Hi，

I used an oscilloscope to check the TX clock signal and found that it was also present. I also compared it with the RX signal. I also used the real-time core  icssg Ethernet to ping, and the clock signal captured by the oscilloscope was consistent with that under Linux. I do not know what the problem is at the moment. yellow is TX CLK，blue is RX CLK.

Hi

I found a strange question.I used phytool command,print this，What could be the problem?

Hello Wanglili,

Oscilliscope

Can you please confirm the Oscilloscope sampling rate? Is it currently 62.5 kSamples / sec?

If the link is 100Mbit, I would expect a clock speed of 12.5MHz. So the sample rate needs to be greater than 25 million samples per second to capture the signal accurately.

phytool command 

I am not sure I understand, what part of that output is concerning?

Regards,

Nick

Hi，

I  confirm the Oscilloscope sampling rate,and modify the rate, in mii mode,clock speed should be 25MHZ.Actually I see the clock speed is 25MHZ.It is correct.

I do not know the phytool command , if the PHY of DP83620 is normal, should not the read BMCR register be 0XFFFF?  I just found this command on the Internet and operated it. Is it possible that the PHY settings are wrong?

Hi,

I corrected myself. The address I gave when using the phytool command was wrong. My phy address was 3, so it should be phytool print eth2/3, and the result is as follows.

root@am64xx-evm:~# phytool print eth2/3
ieee-phy: id:0x20005ce1

ieee-phy: reg:BMCR(0x00) val:0x3100
flags: -reset -loopback +aneg-enable -power-down -isolate -aneg-restart -collision-test
speed: 100-full

ieee-phy: reg:BMSR(0x01) val:0x78c9

flags: -ext-status -aneg-complete -remote-fault +aneg-capable -link -jabber +ext-register

It seems normal.

Hi,

How about the internal delay settings?I want to know the meanings of these settings.

Hi,

Is there any update? 

Hello Wanglili,

Apologies for the delayed responses here. I have been trying to catch another team member to discuss the details of your thread, and we have just missed each other on both Friday and Monday. Will provide another update tomorrow.

Regards,

Nick

HI,

Thank you for telling me. I found an interesting problem. When I changed the “mii-g-rt = <&icssg0_mii_g_rt>;”to “ti,mii-g-rt = <&icssg0_mii_g_rt>;”in dts file,it would appear "icssg-prueth icssg0-eth: couldn't get mii-g-rt syscon regmap";When I changed the “mii-rt = <&icssg0_mii_rt>;;”to “ti,mii-rt = <&icssg0_mii_rt>;”in dts file,it would appear "icssg-prueth icssg0-eth: couldn't get mii-rt syscon regmap".What is the reasion?I am confused.

Hello Wanglili,

clock frequency 

I was wrong above - 25MHz TX and RX clocks are what we would expect for 100MBit.

Devicetree file documentation - use the docs from your kernel version 

When I check Documentation/devicetree/bindings/net/ti,icssg-prueth.yaml for Linux kernel 5.10, I see that the entry mii-g-rt is used. However, when I check for Linux kernel 6.1, I see that the entry is changed to be named ti,mii-g-rt. Make sure to reference the version of the kernel docs that is associated with the kernel version you are using.

PRU firmware

Can you please confirm where you got the PRU Ethernet firmware? Are you using the exact binary files that came in SDK 8.6, or different binary files?

The Linux drivers are only tested with the exact version of the PRU binaries that are packaged in that SDK. If you use binaries and Linux drivers from different SDK releases, things might not work.

Regards,

Nick

Hi,

I confirm the kernel version,it is 5.10, so I use mii-g-rt.

"Can you please confirm where you got the PRU Ethernet firmware? Are you using the exact binary files that came in SDK 8.6, or different binary files?" Do you mean the file "am64x-pru0_0-fw、am65x-sr2-pru0-prueth-fw.elf"and other related file?I used the original image updated with the SD card, and did not change this file separately.

Hi,

Are there any other possibilities at this time?Our project has been delayed for a long time.

Hello Wanglili,

As far as I can tell, pretty much everything looks the way I would expect it to look. There are not any other debug things I am aware of - it seems like your hardware design is probably fine, and your receive signal path is good. It does not seem like there is anything external that would be blocking the TX path, since the clock signal looks fine.

The next step would be for me to see if I can replicate your observations on an AM64x EVM, to see if there is a Linux software issue. I have been told that AM64x PRU Ethernet MII should work on 8.6, but I have not actually tested myself.

This could take me a couple of days, I apologize. Monday is a holiday, so feel free to ping the thread if I have not replied by Tuesday.

Regards,

Nick

Hi,

Thanks for your follow-up, any results so far?

Hi,

Any progress?

I have been waiting for a week, is there any new news?

Do you have any results?

Hello Wanglili,

I apologize for the continued delays. I set up a board for testing, and then got sick. I am returning back to work now, but something happened to my remote board setup so I'll need to go reset the system tomorrow. I am discussing your thread with the developers.

Regards,

Nick

Hi，

I am very happy to receive your reply and hope to get your answer as soon as possible.

I have a little doubt, maybe it is related to the MAC address, a random MAC is configured during initialization, and the MAC address displayed when using the ifconfig command is inconsistent with the random configuration. I just thought of this, I don&#39;t know if there is any connection.

Hello Wanglili,

Verification: MII on SDK 8.6 does work on AM64x EVM

I have confirmed on AM64x EVM, SDK 8.6, I am able to set the port to MII mode, get a link up, and successfully ping my host computer.

One interesting note is that I do NOT see the TX packets showing up on ethtool -S, though I can see the TX packets with ifconfig -a. So it seems like at least with MII mode, on SDK 8.6, ethtool -S cannot be used as a tool to see if the TX path is working or not.

I did double-check with the board set to RGMII mode, and ethtool -S did seem to count packets properly. So it could just be an issue with MII.

MAC address? 

I am not sure whether this would have any impact. I will ask around.

Regards,

Nick

Hi,

I saw your results. You used icssg1, and I used icssg0,you are using a DUAL MAC,and I using single MAC. I think the difference is here.If I can not confirm sending via the ethtool -S command, is there any other way to determine my current status?Regarding the MAC address, I think it has nothing to do with this, because I have the same problem after giving it a fixed address.When I turned Ethernet off and on again like you did, the following message appeared：

I also observe the same behavior occasionally on MII link down:

I am asking the developer if this is expected on this SDK release.

Any suggestions on verifying the TX path? 

If you are able to ping something else, or be pinged by something else, that should be a good indication. ifconfig -a is also giving a count of TX packets that seems reasonable for me.

For example, I showed in my previous response what I am doing to test on my local network where I've assigned static IP addresses of 192.168.1.XXX to the EVMs and my PC.

Regards,

Nick

Hi,

I currently use the ifconfig -a command, and the TX and RX packets are all there, but I can not ping the computer. I also use a static IP, my PC is 192.168.5.253, and the EVM is set to 192.168.5.32.

I want to know about  Why does it appear “icssg-prueth icssg0-eth eth2: xmit timeout”？

And I use icssg0,you use icssg1,Is there some difference？

How can I know which PHY driver I am using?The current chip I am using is DP83620, and its ID should be 0x20005ce1. This is also the value I read out through the phytool command, however, the PHY related information printed when printing is“ davinci_mdio 30032400.mdio: phy[3]: device 30032400.mdio:03, driver TI DP83620 10/100 Mbps PHY”，I saw this name in DP83848.c file, but the ID defined in this file is 0x20005ce0.I think it should not match this driver, it should be the general PHY driver on MII mode, but I can not find the relevant files of the general PHY driver.I have doubts about this part. Can you explain in detail the process of finding the corresponding driver?

DP83848.C

#define TI_DP83848C_PHY_ID		0x20005ca0
#define TI_DP83620_PHY_ID		0x20005ce0
#define NS_DP83848C_PHY_ID		0x20005c90
#define TLK10X_PHY_ID			0x2000a210

static struct phy_driver dp83848_driver[] = {
	DP83848_PHY_DRIVER(TI_DP83848C_PHY_ID, "TI DP83848C 10/100 Mbps PHY",
			   NULL),
	DP83848_PHY_DRIVER(NS_DP83848C_PHY_ID, "NS DP83848C 10/100 Mbps PHY",
			   NULL),
	DP83848_PHY_DRIVER(TI_DP83620_PHY_ID, "TI DP83620 10/100 Mbps PHY",
			   dp83848_config_init),
	DP83848_PHY_DRIVER(TLK10X_PHY_ID, "TI TLK10X 10/100 Mbps PHY",
			   NULL),
};

Use phytool command to check phy ID
root@am64xx-evm:~# phytool print eth2/3/2
ieee-phy: reg:0x02 val:0x2000
root@am64xx-evm:~# phytool print eth2/3/3
ieee-phy: reg:0x03 val:0x5ce1

I have two questions,hope you can answer all.

Regards!
