Hi, I have been looking into DMA on Teensy 4.1 but have recently found Arduino Portenta (STMicro STM32H747XI that has both Cortex M7 and M4). I was wondering if I can utilize the DMA libraries from Teensy 4.1 (of course, with possible adjustments) to implement DMA on the M7 core, or it is simpler to start from scratch?
 
The DMA library for the T4.1 is specific to the IMXRT chip used, it is not a feature of the M7 core.
