Hello liangbowen, as i see, i also work with TSE and marvell PHY.

Now i have workable transmit part from nios to PC, but i have some problems with receiving of packet.

So i can help you with transmit and you can help me with receive.

My configuration is:

Q 8.1 SP1 nios II 8.1

TSE

Marvell 88e1111

I send packets from nios through the MAC level and i want to receive it the same way from the PC.

At first it would be great to now how you made the receive of packet?

i try to make it by alt_avalon_sgdma_register_callback which will be launched after the packet came to PHY->MAC.

But i can't make it to step into the isr function in debug mode, i don't know what is the problem...

So i'll answer all your questions.
