I'm using a Nano RP2040 Connect and a very simple script that keeps track of the run time in minutes. This simple sketch (phase1) was created after having difficulties with a full featured script in an attempt to troubleshoot the problem.
If I run the script as defined above, it runs trouble free for hours. I ran it overnight and had no problems for over 6 hours. I then added support for the 2040 IMU (phase2), and only added reading the X, Y and Z accelerometer values. After a few minutes, the sketch reset, and again 40 minutes later.
Not sure how to proceed from here without adding additional debug statements in the libraries.
Here are my notes and serial port logs from the test...
phase 1 ran with no issues for over 400 minutes.
The test was run from a standalone USB power brick.
Moved the RP2040 back to my macbook, rebuilt with phase2
phase 2 reset within 1 minute, and again 40mins later, here's the log

Running phase2 from the standalone USB power brick, to rule out any influence from the macbook
This test reset after 4 minutes.
Here's the sketch... The sketch includes a "#define phase2" that brings in the IMU. Without phase2, the sketch runs without issues. With phase 2, it resets at random intervals.

In order to verify that it's not a board related issue, I ordered another RP2040 connect, and will run this test again with that new board.
