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?
I found my issue.
I had to set the Master Secure Enable which I thought is not necessary as DMA is a Slave access.
But ok, maybe I have to read these description again to understand it.
