DMA from parallel FIFO via gpio - Raspberry Pi Forums

i have parallel fifo interface consisting of data lines , strobe attached gpios. i'm reading fine via memory mapped gpio lines, use dma.
reading peripherals manual gives me rough idea how configure reading operation. how can generate strobe signal?
can read more how dreq sources work?

hints appreciated!
thanks,
manuel

i haven't used myself, secondary memory interface has dma capable driver: https://github.com/raspberrypi/linux/co ... e30329c1d0

servoblaster uses dma drive gpios , judging readme uses pwm pace it: https://github.com/richardghirst/pibits ... rvoblaster
