AM3517 reference code for DMA to drive SDIO bus

Other Parts Discussed in Thread: AM3517

Hello Sitara forum:

We are looking to set up SDIO on an AM3517 that is running a custom application instead of Linux.  Part of the project involves a high data rate output that necessitates the use of DMA to drive the SDIO bus we are going to be using.

We have not been able to find much in the way of example code for this on the TI sites.

The only thing we’ve been able to pull down is the U-boot driver, but that uses polling.

Is there any reference code or example projects we can reference?

Any feedback or input is welcomed and appreciated!

thanks again!

Paul
