Question1
I am currently working on implementing LPUART on top of the the powermode switch example code. From what I understand, transferring code from different project does not work because of the Freertos configuration/setting the project is defined as. How do I check if the configuration of the Freertos in the powermode switch example code would work in corresponding with the code written LPUART edma example code.
Question 2
If I want to initialize three LPUARTS ports, I was not sure how the DMA channels were selected. I was not able to find any documentation and understand how the value are being selected for TX and RX DMA channel. Also, how do I make sure that the channel I set for UART corresponds to the pins that I want to use on the DEV board for UART communication. This is the part of the example code I am not sure about. How to set the LPUART_TX_DMA_CHANNEL? I am assuming that all the LPUART would be set under one DMAMUX and is that a safe assumption.
/* Set channel for LPUART */
DMAMUX_SetSource(DMAMUX, LPUART_TX_DMA_CHANNEL, kDmaRequestMuxLPUART1Tx);
DMAMUX_SetSource(DMAMUX, LPUART_RX_DMA_CHANNEL, kDmaRequestMuxLPUART1Rx);
DMAMUX_SetSource(DMAMUX, LPUART_TX_DMA_CHANNEL, kDmaRequestMuxLPUART2Tx);
DMAMUX_SetSource(DMAMUX, LPUART_RX_DMA_CHANNEL, kDmaRequestMuxLPUART2Rx);
DMAMUX_SetSource(DMAMUX, LPUART_TX_DMA_CHANNEL, kDmaRequestMuxLPUART3Tx);
DMAMUX_SetSource(DMAMUX, LPUART_RX_DMA_CHANNEL, kDmaRequestMuxLPUART3Rx);
