Example Code for USB Data Transfer with DMA on MIMXRT1040

Hi,

I'm working on USB communication using the MIMXRT1040 and would like to implement data transfer using DMA for better throughput. I've gone through the SDK examples, but I couldn't find a dedicated example showcasing USB with DMA integration.

Could you please let me know if:

There are any existing example codes for USB data transfer using DMA on the MIMXRT1040?

If not, can such an example be made available or shared?

Any guidance or pointers to documentation/resources would also be highly appreciated.

Thanks in advance!

Hi @akash347,

Unfortunately, we do not have any examples that implement the USB stack integrated with DMA. As mentioned in the following community post, we have examples for both DMA and USB separately, and the integration would have to be done by the developer.

Edwin.
