SPORT DMA Memory Access or Fabric Error

Hi,

I've tried to start with the ADSP-21569 evaluation board to transfer an old ADSP-21489 project.

The DSP is booting, TWI setup is working (ADC, Codec, Switches) but SPORTs refuse to work.

I've compared the registers with the Audio_Passthrough_I2S_21569 example in CCES but the differences do not give me a hint for my error.

The only part I'm not using is the SPU secure stuff from the example, this registers I don't touch.

I think my setup has the correct sequence but when I set the DMA_CFG register (DMA10 or DMA11) an error immediately rises.

"Memory Access or Fabric Error" in the DMA_STAT.ERRC field.

What can cause this error?

Regards

Christian
