This device is relatively powerful. I'm able to run Fedora with Wayland on similar device (iMX6SL-evk). DNF is slow for first time, so I need to wait 20 minutes until all data is parsed, but then works fine.

It was an ARM Cortex-a9 with NEON extension instead of ARM Cortex-M7. It is basically a different family of i MX processors.
