deepSleep not working on Nucle-L476

Open PerennialNovice opened this issue 5 months ago • 0 comments

I tried the TimedWakeUp example on Nucleo-L476 and found the user LED blinking very fast, not like it should. The very same example works well on Nucle-L073

some additional findings:

  • using sleep instead of deepSleep makes L476 work

  • adding serial output makes both boards not work - UNTIL I add Serial.flush() before the sleep()

    • deepSleep still does not work on L476
