OpenLog Artemis - Won't Run/Reset with uSD Inserted

New SD card arrived today and the unit is now working as expected. @PaulZC I think you are correct re brownout, thanks for the assistance.

Couple last notes for posterity:

  • - RTC was reset often/always(basically every time I got it working again)
  • - I was suspicious of the USB power (handshake or controller issues), so I tried running on battery only, but saw the same results.
  • - I also tried running it from a cell phone charger (again suspicious of the USB connection), also same results.
  • Finally the card that worked was a Sandisk Ultra 16GB UHS-I. The bad card was a 32GB Kingston Canvas Select Plus (also UHS-I).
