Tool/software: Linux
Hello.
I have to do DMA transfers triggered by EDMA_EVT1 pin.
I see the DMA1 channel reserved in the linux kernel devices.c file, so in my understanding, I need to use the crossbar.
But the crossbar configuration is also defined in this devices.c file as static and the API functions do not provide a way to change it.
So, the question is:
If I ask edma_alloc_channel () function for a channel, I may be given an arbitrary DMA channel - how can I set the crossbar with the correct value for the received channel?
Thanks a lot ahead.
