I am working on integrating lwIP into my design, and I have been using the files that are provided by LPC. However as soon as I fire it all up and start the DMA & EMAC, I get a Fatal Buss Error & and over flow. The current receive descriptor doesn't seem to change from the initial descriptor.

Does anyone know what would cause the FBE? Obvious answers would be a problem transferring the data, but it is coming out of SRAM, so I don't see why it would fail.

Also, is anyone aware of any errors in the LPC lwIP code?
