TMS320F28388D: Issue with connectivity manager ethernet example 10

Part Number: TMS320F28388D

Hi,

I was trying to run the ethernet example 10 which uses DMA to manage reception/transmission with the evaluation board.

However it doesn't seem to work properly.

The generic ISR gets triggered all the time, incrementing the genericISRCount variable.

In the generic ISR, the fragment number retrieved in that function never gets incremented nor does the transmit ISR count and receiver ISR count variables.

Did I miss something ?

The ethernet_cm_config is running on CPU1.

Best regards,

Clément

Hello Siddharth,

I did not hear back from you since 10 days.

Clement,

Sorry for the late response.

I tried to run the example on the Control card. I observed that the transmit and receive ISR are triggered only once . Thereafter the generic ISR keep increasing and the fragNumber keeps changing.

I am debugginhg why the early interrupt gets triggered continously even when the packet is sent only once.

Haven't been able to figure out the cause for this behavior. Will continue debugging and keep you posted.

Best Regards

Siddharth
