Hello - I'm seeing some odd behavior trying to get my OpenLog Artemis up and running.
Hardware:
OpenLog Artemis (no IMU) running 2.2 firmware
Qwiic NAU-7802 module
32GB uSD card (from Sparkfun)
Problem:
When powering up (via USB-C to my computer) the OpenLog Artemis I get no lights. Hitting reset results in a single flash of both the STAT and PWR led. My computer detects the Serial Adapter, but I cannot connect to it.
I have managed to get the system working again by removing the uSD card, powering on (via USB) and then hitting reset. The device come online, LEDs blink as expected, and I can connect via Serial. Once I disconnect and/or power down the system, inserting the uSD and power back on gets me back to no lights/no activity.
One thing that works is reseting the OpenLog Artemis (via the serial commands). When this is done the PWR led stays on even after removing the USB cable. I can then insert the uSD card (which causes the PWR light to go off), power on the system (via USB), and then it works as normal. However if I disconnect and reconnect the power, it stop working again (no lights).
Other things I've tried:
-Reformatting the uSD card using the recommended formatter (full format)
-Deleting everything from the uSD card
-Having the NAU7802 module connected and disconnected (no difference)
-Powering via battery (Sparkfun 1200mAH Li-Ion module)
I also have a new uSD card on the way in case this is a buggy uSD.
