Hello,
I'm having a problem about the SPORT and Host DMA order initialization.
My project with BF527, works correctly with the initialization order below:
// 5) Configure SPORT
  configureSPORT();

// 6) Configure Host DMA Port
  configureHostDMAPort();

// 7) Init SPORT
initSPORT();

But, i need initialize the Host DMA first, then start the SPORT:

// 6) Configure Host DMA Port
  configureHostDMAPort();

// 5) Configure SPORT
  configureSPORT();

// 7) Init SPORT
initSPORT();

 

When i do that, the HOST DMA doesn't work.

 

The function code is attached.

 

Any ideia?

 

Regards,
