Hello,
I am trying to configure the DMA with MCUXpresso Configuration Tools
Now I have this:
but due to the RT1170 Reference Manual, the MCU should have two DMAMUX module (0 and 1)
RM1170 Page 129
Why is there only one DMAMUX module in the tools available?
Hello,
The DMA and DMAMUX devices are core-specific on RT1176. Specifically, the DMA0, DMAMUX0 are available only on Cortex-M7F and DMA1, DMAMUX1 are available only on Cortex-M4F.
In the Config Tools you can switch the core under File -> Select core menu (sets the core for the application project). In the Peripherals tool's Functional Group properties dialog (see picture below) you have to select the core that you are initializing.
The DMAMUX peripheral initialization is part of the associated DMA (eDMA) peripheral.
