Problem of ENET_EIR [GRA] interrupt

[t_kaz]

We developed the board using imx6 solo and Linkstreet (Ethernet switch) of Marvell.

However, the board has a problem which an ENET_EIR [GRA] interrupt occurs and transmitting stops, when traffic increases.

.

The occurrence of cause of GRA interrupt is mention to the reference manual(23.4.9.4.1 Graceful transmit stop (GTS)),

but that doesn't apply to any of them.

I think that the Marvell tag added to the header caused problem.

Then, please let me know about following,

- When it stops by GRA interrup, is there any method of resume transmission?

The method of clearing ENET_TCR [GTS] was not effective.

-I think that the Marvell tag is misrecognition to be pause frame.

Is there any method of disable pause frame?

Hi,

Did you try disable flow control? ENET_RCR[FCE].

How you clear the ENET_TCR[GTS]?

What is state of ENET_TCR[RFC_PAUSE] in your unpleasant situation?

Thanks,
