Original question:
PROCESSOR-SDK-AM62A: Need to set up a OSPI Cyclic DMA Transfer that is GPIO Triggered
Tool/software:
Hello Bin,
I have new H/W so the interrupt pin that is asserted low when data is ready to be read from the slave QSPI is now inverted so that it will generate a rising edge. Can you guide me on setting up the code so that interrupt pin will start the QSPI transfer?
Thanks,
Victor
Hi Victor,
Sorry for my late response. This thread has been routed to a different TI folk, and just got in my hand today.
For GPIO triggered DMA, please refer to the following e2e thread in which I have done the similar work for a different customer.
AM625: Rerouting interrupt to DMA event and DMA_DEV_TO_MEM channel selection
Please start reading from the middle of the second page of the thread around my post screenshoted below (before this point it was about sw triggered DMA).
