MCF5485 FEC Documentation

kchaloup — Mon, 10 Apr 2006 23:29:57 GMT

I'm trying to port a 5272 network driver to the 5485 and cannot find detailed information about the 5485 FEC other than the reference manual. Is there any detail documentation that describes the 5485 FEC other the the referance manual? I would like more info on the buffer dscriptor flags, etc.

Unlike the 5272 (and 5282, 523x, 5275, etc.), the FEC on the MCF547x/8x devices does not have a dedicated DMA. Instead, the Multichannel DMA is responsible for servicing the FEC FIFOs along with the FIFOs of the other CommBus peripherals. The Multichannel DMA API does provide tasks that emulate the buffer descriptor behavior of the FEC with a dedicated DMA.

Please refer to the Multichannel DMA API and the sample software on the web for more details.
