How to use DMA uart in TI RTOS?

Other Parts Discussed in Thread: CC3200

Hi,

How to use DMA uart in TI RTOS?Do we have to generate our own drivers for it ?

  • Hi Ramakumar,

    As of the 2.10.01 release, UART with DMA is supported on TivaC & CC3200 drivers.  DMA support has not been integrated in the UART driver for the other device families, you will have to add this functionality.  

    However, all SPI drivers already make use of the DMA to assist with the transfers, so with the SPI driver source (<tirtos install dir>/packages/ti/drivers/spi) for the device you are currently developing on and the TivaC or CC3200 UART+DMA driver (<<tirtos install dir>/packages/ti/drivers/uart/UARTCC3200DMA.c/.h), you should be able understand the driver structure and implement it.  

    Regards,
