Can TI provide a RM57 RAM to RAM DMA example?

Yuncheng Song

Hi all,

Can anyone from TI or Hercules user provide a simple RAM to RAM DMA example? No matter how I tied, there is no data transferred. I doubt the RM57 chip does not have DMA ports connected. In addition, the supplied example of MIBSPI DMA does not work either.

It will be great if there is an simple example to demonstrate RAM to RAM DMA functionality.

Best,

Yuncheng,

Please check this forum post

You will need to change the CPU endianness from "big" to "little".

Thanks and regards,

Zhaohong

Yes, your code works really well

And I found the bug in my code, which is the incorrect MPU settings

Is there any code available for above thread ? RAM to RAM data transfer using DMA with PSA Register check for data integrity.
