1. S32DS 3.6.10
2. chip S32K358
3. RTD: 7.0.1
problem: dma emux has no instance 1 ,just instance 0
this chip should have two instance of dma mux, but now the config tool just one.
I want to use LPUart4 DMA,but it is in mux1.
Someone give me a help.
Hi,
There is a single DMA module with 32 DMA channels and two DMAMUX instances. Each DMAMUX instance provides 16 channels and is mapped to half of the DMA channels.
As the LPUART4 TX request is routed to DMAMUX1, you need to use DMA channels 16-31.
The DMAMUX configuration is handled in the RM component, so please add the RM component to the project and configure it accordingly.
BR, Petr
