mpc8306 DMA for UART and CAN BUS

[00lirui]

Hello.

  Can I  take advantage of DMA  for UART receive and transfer data? Is there some code example for it ?

  thanks!

Which UART you are using - DUART or QE UART?

[00lirui]

DUART,  But can it work on QE UART?

[Pavel]

The main advantage of the DMA is that DMA and Core can access the SDRAM simultaneously. The DMA has the advantage that it can execute bursts on the bus.

It reduces utilization of the core.

See attached file. It is simple program example for DUART FIFO using on the MPC8349.

Similar code can be used on the MPC8306.

Thank you,

But the code I can see is something about DUART FIFO,not take adantage of DMA.

Am I right?
