Hardware: S32K388
Issue Description: I am facing issue during generation of UART config. It's complaining saying LPUART4 and LPUART12 are using same source channel of DMA Method and asking me to configure only one of LPUART4 or LPUART12. But for my application, I need both of the channels to be configured.
I made sure that I am using different DMA channels when I configured Rm and Mcl.
Is this error with Tresos generator? If not, please help me with identifying the problem here. Thanks.
Hello @Gnanesh,
This is a HW limitation.
There are many peripherals but not many DMAMUX slots, therefore, some of the DMAMUX sources are routed to more peripharals.
Like source 43:
That means that if either of the LPUARTs received data, it would trigger both DMA channels and both LPUART DATA registers would be read by the DMA at the same time.

Daniel
