CC2745P10-Q1: cc2745:Conflict between spi's dma and uart's dma

Part Number: CC2745P10-Q1

Tool/software:

Hi, TI:

When I use spi0 and two UARTs on CC2745, the DMA of UART1 will conflict with the DMA of SPI0 and I can't use both UARTs at the same time.

Is it possible to use spi and both UARTs at the same time?

Thanks

James

Hi James,

Can't you use a different DMA channel? You can for instance change the SPI DMA channels to DMA_CH6 and DMA_CH7.

Hi Haiatullah,

My customer has the same question. Channel 6 and 7 are used for SPI1, but SPI1 is already used. Is there a way for UART1 and SPI0 share the DMA channels?

Best regards,

Shuyang
