Trying to get an ethernet connection with a evm6678 evaluation board.

Bert Follon

Hello,

We are trying to make a ethernet connection with a evm6678 evaluation board however it doesn't work out how it should. First things first I try to get the hua_evmc6678l example working however initial i get 9 errors which concerns somthing about this variable sin1.sin_len = sizeof( sin1 ); by looking on the internet I found out https://e2e.ti.com/support/embedded/tirtos/f/355/t/425455

Afterwards i was trying to write to the board and successfully this works (with all the switches in default position = first position from following link http://processors.wiki.ti.com/index.php/TMDXEVM6678L_EVM_Hardware_Setup ) I was even ably to run the program until I get following errors

[C66xx_0] QMSS successfully initialized 
	  CPPI successfully initialized 
 	  PA successfully initialized 
  	  PASS successfully initialized 
 	  Ethernet subsystem successfully initialized 
	  Ethernet eventId : 48 and vectId (Interrupt) : 7 
	  Timeout waiting for reply from PA to Pa_addMac command
	  ti.sysbios.heaps.HeapMem: line 354: assertion failure: A_invalidFree: Invalid free
	  xdc.runtime.Error.raise: terminating execution

then again i was able to find something by using google namely a site stating the switches should be in a no boot position however when i tried this I get following error:

http://processors.wiki.ti.com/images/f/fd/CCSv5_data_verification_error.png An there I'm stuck nothing seems to work anymore so my question what should I do?

Bring the switches back in the first position?

And if so how can I solve the first problem then?Can someone help me out.

Thanks.

Bert Follon,

Welcome to the TI E2E forum. I hope you will find many good answers here and in the TI.com documents and in the TI Wiki Pages (for processor issues). Be sure to search those for helpful information and to browse for the questions others may have asked on similar topics (e2e.ti.com). Please read all the links below my signature.

Please go through below pointers to run the hua demo,

You can also run the NDK examples available in MCSDK 2.x. Please refer below wiki.

Thank you.

Dear Bert,
Sounds like you are running the NDK examples without doing board RESET or without reboot the board (remove the power cable and plug it again)
As of now, the code is require FULLRESET for running the NDK example in case if you loading the code in second time.

I got the same problem when I ran the NDK example two times (one by one) without doing reset the board.

Ex:
Connect target -> Load the NDK example & run -> Disconnect the target -> Load the NDK code again & run -> Issue

As document says, you would get the errors when you do multiple frees.

software-dl.ti.com/.../HeapMem.html

Please make sure that you are not doing.

PS: You have to set boot mode to "DSP-no boot" mode for running the examples on target through CCS.

Hope this helps.

Let me know if any problem.

Hey All,

Thanks a lot for all your feedback finally it works just for further reference what i did:

*I reinstall mcsdk_2_01_00_03 an then compiling and linking works out of the box.

*I put the switches in default mode not in the no boot mode and then it works fine

*I use packet sender to send message and I get them back easily

Just for the second point can this be explained by the fact I'm not using the standard evm6678 but the standard evm6678 with a interface on top of it. like this:
