SPI in slave mode with DMA

Shahid Ahsan

AM3359X. SPI in slave mode / DMA does not work. I get no events or interrupts. SPI in master mode with DMA works fine. Are there any known issues with this?

Hi Shahid,

What software are you using?

Hi,

I am using for baseline the DMA example code from StarterWare \AM335X_StarterWare_02_00_00_07 mcspiFlash_edma.c sample code.

Regards,

Shahid

There is a dedicated Starterware forum http://e2e.ti.com/support/embedded/starterware/f/790 I will move this thread there.

In StarterWare 02.00.00.07 User Guide - Texas Instruments Wiki (page 6).
"Slave mode of McSPI controller is not supported in StarterWare."

It is not supported in StarterWare that I know. I need to know if I implement SPI slave mode ( which I have and it works) will it work with DMA (which is not so far). Thanks.

Hi Shahid,

Did you manage to get this working. I'm currently trying to get McSPI and EDMA working in Slave Mode (Receive only) and I cannot get the EDMA RX event to trigger.

John
