Hello everybody,


I have an application where we need to receive 8 audio channels via TDM format. For this purpose, I am using the SAI module. For improving the performance, I want also to use the eDMA of the device.


The problem is that with the SDK I have not been able to receive anything, it always stops after the first transfer.

What I have tried is to follow the example in the SDK's API, but it is using DMA (not eDMA), and I haven't managed to get it working.


Does somebody have some working example?


I am using a Kinetis K64 device.


Thank you in advance,
