S32K312 UART Transmit & Receive Using DMA

[li3]

Hello, I am configuring UART to transmit in DMA mode.it is difficult for me to configure other channels by referring to the additional code project. Can you help me configure the sample project of the UART2 channel and upload the configuration picture? thank you.

I configured the new project UART6 through the configuration item of the attached project example, but it failed. Is the configuration missing?

在Dma_Mux配置DMA物理通道，即可使用DMA

Thanks for sharing.
I am glad to hear that it works now.

你好

为什么在配置 RM 组件时，DMA Mux Sourse 中只能选择 UART0 和 UART1 通道？

谢谢。

DMAMUX_0 and DMAMUX_1 channels are mapped to eDMA_TCD 0–15 and 16–31, respectively.
excluding S32K312 where
DMAMUX_0 and DMAMUX_1 channels are mapped to eDMA_TCD 0–5 and 6–12, respectively.
So please change the Dma Hardware Channel.
