Concerto F28M36 Ethernet example does not work

Hi,

The example does work! Are you using the exact sample code or its your custom (modified) implementation?

Regards,

Gautam

Hello Gautam,

Thanks for reply.

I was using the exact sample code version v201 on F28M36 ControlCARD. Through a Crossover RJ45 cable,with fixed IP address "169.254.42.86"  and Subnet mask "255.255.0.0"  set up on the PC, I can neither browse nor ping "169.254.254.169" which has been setup on the controlCard.

Then I modified the PC address to "192.168.1.2", ControlCard address "192.168.1.1", with subnet mast"255.255.255.0", still could not communicate. BTW, I tried both RAM and FLASH of enet_uip example.

Do I need to modify some I/O setting to make the sample code work?

Thanks.

Hi Hao,

That's really weird.  You went through all the details in "F28M36x-FRM-EX-UG.pdf" right? BTW which example code are you using? I'll try to look into it.

Regards,

Gautam

Yes Gautam,

I went through "F28M36x-FRM-EX-UG.pdf", and successfully tried blinky_m3 and blinky_c28, both on FLASH and RAM.

For the enet_uip, I tried v110,v200,v201 of ControlSUITE, none of which works. Yellow light of my RJ45 is ON, the green light blinks for like 20s, then stay OFF.

Let me know what you think, Gautam. Thanks a lot.

Hao

Modified the MAC address as is on the label, still no communication.

Hi!

If I understand you went through this already (5228.F28M35x_Workshop_2-0.pdf & 5125.TI_F28M35xx_InfoSheet_06_13_12.pdf)?:

MAC Address
F28M35xx device Ethernet examples use a fixed TI’s MAC address: A8-63-F2-00-00-80. Refer to the board label for a unique TI’s MAC ID assigned for each F28M35xx controlCARD. User applications can program a fixed MAC address in the non-volatile memory reserved for MAC address.

Regards,

Igor

Hello Igor,

I went through the files, but did not run the Lab examples, since I don't have a F28M35 controCARD. Is there another workshop for F23M36?

I have successfully tested several c28 and m3 examples.

For the Ethernet example, I believe the code in ControlSUITE must work, I am definitely missing something here. Does the MAC address really matter? So far, it does not work for me, before or after changing it.

Please advise.

Thanks.

Hao

Hi Hao!

Sorry. Yes, I am a little confused. But both uC have the similar architecture. It seems workshop for M36 is absent  as yet. Do you have control card only or kit TMDXDOCK28M36? Do you have any manual for control card? I think that situations with MAC address for M36 control card & M35 control card are similar. But this is my surmise mere.

Regards,

Igor

Yes, Igor,

I am using TMDXDOCK28M36. All the examples and manuals are in controlSUITE. Nothing came with the box.

I follow the firmware instruction pdf of M36, it just did not work for this example yet. Maybe I'll try to realtime debug the code, to see if there's anything interrupt from the Ethernet at all.

Thanks.

Hi!

Did you try to use this driver UG 8712.F28M36x-DRL-UG.pdf (p.49-63, on p.62 is the simple ethernet example)?

Regards,

Igor

Hello Igor,

I will try that. What PC terminal software you recommend for testing Ethernet?

Thanks.

Hello Hao!

I would recommend you WireShark http://www.wireshark.org/download.html.

Regards,

Igor

Hello Igor,

I have WireShark for capture the packets.

I was wondering if there's any software simply operate the Ethernet port(not IP), to send/rcv single packet, as an easy way to verify if the port is functional at all.

Thanks.

Hi!

I don't understand why you don't like WS. This sniffer provides wiretapping any data which enter in Eth-port. Its disadvantage is that it does not generate packets itself. But at first in my opinion you need to make sure that your MCU generates packets. About generation of packets from PC I can't suggest ready application. Perhaps it exists and one might find if to search carefully...But on other side, writing the socket is not a very difficult task in the presence of a heap of source code in the network.

Regards,

Igor

Thanks for the advice, Igor,

Are you saying that I can programmed the MCU to just broadcast an Ethernet packet, without a destination address? and Wireshark is able to sniff it(together with my MAC addr)?

Hopefully I can get something encouraging by doing that.

Hello Hao!

As far as I aware WS allows to do this unlike other sniffers. Anyway you need to try.

Regards,

Igor

Hello Igor,

I tried "EthernetPacketPut(ETH_BASE, pucMyTxPacket, ulMyTxPacketLength);" as is driver example code. The program is trapped at:

   while(HWREG(ulBase + MAC_O_TR) & MAC_TR_NEWTX)
    {
    }

This is happening each time I try to run EthernetPacketPut twice. Nothing has been showed on WireShark yet.

Did you ever experience this kind of problem?

Thanks

Hi!

If you try an example from F28M36x-DRL-UG.pdf  at first you can attempt in debug mode thus:

while(1)

{

EthernetPacketPut(ETH_BASE, pucMyTxPacket, ulMyTxPacketLength);

}

Regards,

Igor

Hello Igor,

I did try that. And "EthernetPacketPut(ETH_BASE, pucMyTxPacket, ulMyTxPacketLength);" only ran once, and it's trapped waiting at the second cycle, at "while(HWREG(ulBase + MAC_O_TR) & MAC_TR_NEWTX)" in ethernet.c.

Seems that the packet has never been sent out. Could that be hardware problem?

I have 2 control cards of M36, neither of them works for Ethernet.

Thanks.

Hi!

I see. I think this is the last thing to sin on hardware and this is counterproductive. You need to understand this while(HWREG(ulBase + MAC_O_TR) & MAC_TR_NEWTX) if you is trapped into. At first try to define why both members of the concatenation are TRUE. Try to analyze code of ethernet.c file. And does WireShark see one packet once at least?

Regards,

Igor

Hello Igor,

Not a single packet on Wireshark. I have tried turning the board ON and OFF many times, with each time reloading the above program. My next step could be monitoring the I/O activities between the on chip MAC and external PHY, I guess.

Please let me know if you have any concern based on your experience. Thanks.

Hi Hao!

Yes, of course...Perhaps it makes sense to go back to the ethernet example projects of controlSUITE. BTW do others example projects work still?

Regards,

Igor

Yes Igor,

I tried some examples, mostly c28 though. For m36, I only tried blinky_dc_m3. I will try some other examples, since I could not figure out a way why Ethernet not working.

BTW, the crossover cable I am using only have 2 pairs crossed(1-2 and 3-6). I did not cross 4-5 and 7-8. Do I need to do that for controlCARD? The cable works for two PCs.

Thanks.

Hi!

If your crossover cable connects two PC successfully then this cable is right. But I would try to use also the direct cable (not crossover) between your device and PC (just in case). BTW what about  above "WHILE" (do you sit in it still?). 

Regards,

Igor

Hello Igor,

What do you mean by "while"? Are you talking about "EthernetPacketPut" in the cycle I was trying to run? If so, I can say yes it's still sit in still.

I'm trying straight through cable now.

Thanks.

Yes, Hao. You understand me rightly.

Igor

Hello Igor,

I tried straight through cable, which did not make any difference.So I change it back to crossover cable.

Also I redefined all the I/Os. Now the program no longer sit still in "while", but "EthernetPacketPut" keeps running over and over(I added LED toggle before and after EthernetPacketPut).

But still, nothing showed up on wireshark. One of the RJ45 light barely turn on, while the other is constantly on.

Any more suggestions?

Thanks.

Hi Hao,

What is length of your packet (haw many byte do you try to send)?

Sorry. I didn't understand something. Did you try direct cable (not crossover)?

Hao Wang3 said:

If you stop program in debugger what do you see on RJ45? Does any change?

Regards,

Igor 

Hello Igor,

My packet is "abcd", length is 4(also tried 5, no difference).

RJ45 light does not response to my "EthernetPacketPut", no matter crossover or direct through cable. Actually, most of time RJ45 lights do not response to my program. The only time I can see they response is during the time M36 resetting TLK110, when both lights turned off for 2 seconds and back on. After then, orange light keeps ON, and green light will blink for 20+ times and then keep OFF. And it will keep doing that with/without my program running.

I am reading TLK110 datasheet, looking for a way to trouble shoot. Could that be the problem?

Thanks.

Hi!

1 Well packet length one might increase (up to 100-500 bytes).

2 Now it is very difficult to say where is issue (or issues), but anyway one should check all ideas.

3 About WireShark (just in case). When installing it is necessary to fill check box PCAP. Try reinstall WS and check this also.

4 What MAC addresses did you try?

Regards,

Igor

Hello Igor,

Good news. I increased the packet length to 50+, finally got Ethernet packet on wireshark. Although could not see the right MAC address. But when I pause and resume the program, I can see the packet clearly stop and start showing up on wireshark.

Now I guess I can continue to work on the IP. Thank you so much Igor.

This is the best day of my week.

Hao.

Hi Hao!

I am pleased that our virtual collaboration has led to positive results. I wish you continued success. Keep me posted.

Regards,

Igor

Hello,

I am having a very similar problem.  I also have an F28M36 with the DOCK kit and cannot see any packets on Wireshark on the PC.  I followed everything in this thread and am still getting stuck the second time through EthernetPacketPut at the line that says:

while(HWREG(ulBase + MAC_O_TR) & MAC_TR_NEWTX)

.Even when I crank up the packet length to over 50 as suggested by Hao, it still stays stuck there.  Here's my code:

Hello Phil,

Attached is my code of Ethernet broadcasting. Please disregard the IPC and I/O operations.

Similarly, I will always be stuck at:" while((temp1&0x0004)==0)",  because the PHY link was not active when m3 first started. But if I restart the program, it will pass through, all the way to the packet broadcasting main loop. I can see the packet I sent on Wireshark. I tried in FLASH, which also works.

I did not have a chance to work on software lately. But let's keep in touch, it'll be helpful if you got some progress in this uip thing. Thanks.
