No EMAC interrupts generated on the 6486 or 6472 reference board.

Hi,

I am trying to modify the Helloworld_evm6472 project that came with MCSDK1.0 to work on the custom reference board with a C6486 on it. I removed the platform specific EVM inits.

Here we do not have a PHY. But the FPGA sends ethernet frames to the DSP at a fixed MAC address. I have configured the PLLs correctly and set the EMAC receive filter, MAC address correctly I think. So, EMAC0 - RXGOODFRAMES register increments. I verified that the interrupt initialization is also okay.

But, I do not see any interrupts generated i.e I am never able to hit the breakpoint in emac_rx_packet() in the EMAC driver.

Can anyone tell me why no interrupts are generated?

 

Thanks.,

Arun
