AM3359 IDK with EtherCAT-example

Thomas,

could you solve the issue? What code are you trying an how?

There are differences between ICE and IDK for boot. Make sure you use the binaries from the SDK 1.0.0.3 prebuild binary package. If you boot from SD this card needs to be bootable. First file needs to MLO and then APP.

Regards.

Hi Frank!

Yes, I've also tried the pre-built-variant for IDK from the SW-package already present on the SD-card, but I haven't been able to solve the problem yet. The very strange behaviour of the IDK is the fact, that only on J9 a physical port (a sort of connection) could be detected and one of the activity-leds of the PHY-conn. is on. But if the cable is connected to J8 as being described not any connection could be detected. Well, however, both connections cannot be recognized by TwinCAT as being a EtherCAT-box.

Note: The application code itself seems to be started, as I can see the welcome-message on my terminal-program, which is connected to the IDK via UART-plug.

Addition Note:

The ID-msg. of the application is: ECAT Limited Demo - 1.0.14

Thomas,

yes, EtherCAT has a clear definition of IN and OUT ports. J8 is IN and J9 OUT in our case. Currently we do not support redundancy mode which allows to connect a slave via OUT in the same way as IN.

Now if the application is working and you can see link and packet activity on J9 but not on J8 then it might be that the port J8 on your board is broken. Do you have an emulator now that would allow more debug using CCS?

Regards.

Hi Frank!

No, we didn't obtain an emulator yet, Sorry! Thus, I'm not able to debug the application on the IDK. I will try to validate, that J8 is broken. BTW. is there any jumper-field which might or might not be configurated wrong? Or is there any other way to get more hard evidence?

I'm having the same/similar symptoms with my IDK.  Application seems to be running, but cannot connect to TwinCAT.

I connect TwinCAT to J8, scan devices and get three "Device 1 (RT-Ethernet): Link lost" messages in TwinCAT.  D1 on the IDK does not turn on when connecting to J8.  If I connect to J9, D2 turns on as well as the green LED on J9.

I can switch back to the ICE and connect, control, etc. from TwinCAT without issue.

I have the XDS510 USB emulator.

It is pretty strange to see the issue reported twice. However I am not able to reproduce this yet.

So I need to defer to the factory for some more tests. I assume you are running the supplied pre-build binaries to avoid any tools issues.

Regards.

I am using the unmodified SD card that came with the IDK.

I just tried again with our board. No issue at all using J8. Do you see the output LEDs (D20-D27) running? If not your SD didn't boot.

I asked around internally about XDS510 USB support for AM335x. I am using XDS560 here. I remember that initial releases of CCS 5.1 did not support AM335x and XDS510 combination.

Regards.

Yes, the LEDs are rotating in a circular pattern.

I just tried the latest version of CCS (build 5.1.1.00031), but no difference except I am now able to test the target configuration for the XDS510 USB from within CCS instead of using SDCONFIG.

Thanks.

 Hello Thomas,

I have the same question as you. Do you konw how to slove this problem now? Would you mind helping me slove it?

Hello Frank，

I have the same problem as Thomas, I don't know how to slove this problem, Would you mind helping me slove it?

Hello guys,

Can anyone try a crossed cable to connect between IDK and PC ?

We have observed similar issue here on IDK we solved it by using a crossed cable. 

Please let us know the results. If using a crossed cable solves your problem, then PHY's auto-mdix is disabled. Enabling auto-mdix should solve the problem.

Thanks and Regards,

Shahid

Hello Shahid,

It's OK now, I have used the crossed cable to connect between IDK and PC. Thank you for helping me.

Regards.
