i have problems driving lpc gpio port using dma. When i write with dma to any ram adress everything  works fine, but when i write to any of registers associated with gpio nothing happens.

My question is... Can 824 use dma to write to gpio.

Based on block diagram of 824, GPIO is connected to ARM M0+ but not to this true?
