Peripheral Tool doesn't init DMAMUX automatically when init DMA

It seems that peripheral tool doesn't init DMAMUX automatically when using DMA. Is that a issue?

Hi ,

Is it possible that you could confirm the MCU that you are working on?

Please look at the image below, I am enabling the DMA using the FRDM-K64. If I select a preset option, the code preview shows how will be set up for this peripheral.

Regards,

Mario

Oh I finally found "DMAMUX_Init()" here...

I thought it should be initialized inside "DMA_Init()", but it's not. It made me wonder for a while.

my bad here. thanks for your time anyway.
