With version 8.0.0 beta.0 I consistently crash into HardFault from this line:
from adafruit_bme280 import basic as adafruit_bme280
If I comment out this import and the things that depend on it, then the file will run consistently without crashing. (albeit, not much left actually happening in code.py with the import and things removed).
On Version 7.3.3 with same device I don't get the same crash, instead see the normal ImportError for missing module.
The HardFault seems to be tied specifically to starting the code.py with ctrl-D in the REPL (or perhaps just tied to a "cold" boot?). If the script runs due to code.py file being changed / saved then it doesn't HardFault and instead gives the normal ImportError. Then with same exact code.py file loaded unplug/replug connect REPL. I know it has already crashed because the main loop prints do not occur. I'm unable to connect serial quick enough to know what the initial crash is though. Pressing Ctrl-C then Ctrl-D at this point will restart the code and is consistently leading to the HardFault.
If I install adafruit_bme280 library then it doesn't HardFault or crash, and everything runs successfully.
Description
No response
Additional information
If there is any further testing or diagnostics that may be helpful I'm happy to try things and report back. I seem to be able to reliably re-create the HardFaults.
