TMS320C6678: NDK EMAC problem

dariush karami

Part Number: TMS320C6678

Board: customized

CCS: V7

Some times when I run my program the ethernet printed an error message as below:

To solve the problem, I reset the boards and reload the program again (sometimes several times) and finally, the problem solved.

What should I check? Is the problem from NDK driver or hardware? Please, guide me.

Hi,

Do you use processor SDK RTOS? Which version?

Is it possible to use jtag and see where your app code fails exactly? The log is not very clear at pointing in the root cause of the problem.

Best Regards,
Yordan

sorry for my delay.

I use MCSDK V2.1.2.6.

I must mentioned that I change the reference clock of SRIO and SGMII SERDES from 312Mhz to 250MHz, when I change the reference clock I see

this problem a lot and randomly. I did not see this problem before I change the clock or it was little.

The NDK is library and it is difficult to add all sources of library to my project(if it is necessary I will do it).

Please, guide me.

Regards
