DMA Bus errors when reading from ADC

[marksheahan]

I am trying to read from the ADC at 500KHz, and store it in a buffer. Interrupts weren't fast enough, so I want to use DMA to move data from the ADC result registers into the buffer. There is a bus error on source when reading from the ADC result registers. What might be causing this?

The device is a MCF52235.

Thanks in advance,
Mark

Fixed, by setting master privilege register to include the DMA controller

Thank you so much for this!

Had to set PBRIDGE0.MPL2 = 1;

GREAT!
