CCS/TMS320F28069: USB Bulk Transfer Controller Using Dedicated DMA.

Part Number: TMS320F28069


Tool/software: Code Composer Studio

Hello,

I try to send data with usb bulk transfer. I want to use with DMA.

Are there any resources/examples available for using the DMA controller in device mode of TMS320F28069? I have checked out the usbdaudio.c and usbdmsc.c file because it does provide an example of using DMA with endpoints similar to what I will need to do DMA.

I tried to modify the usbdbulk.c and usbdbulk.h based on the usbdaudio.c and usbdmsc.c but it didn't work. I found a issue about same problem but no source file.

If you know about this issue. Can you post any example usb bulk transfer with DMA??

Issue link about same problem : e2e.ti.com/.../318471

Thanks for your replies.
