I was reading the article about tensorflow lite on SAMD51 here and tried it and failed to compile.
It was the example from the arduino tensorflow lite lirabry and doesnt seem to compile.
Selected Adafruit M4 boards and failed to compile, but can compile with ArduinoMKRZERO(SAMD21).
Here follows the error message:
Arduino: 1.8.12 (Mac OS X), Board: "Adafruit Grand Central M4 (SAMD51), Enabled, 120 MHz (standard), Small (-Os) (standard), 50 MHz (standard), Arduino, Off"

Please let me know if anyone has any ideas, much appreciated.
