Hi All,

I have an app, based on the Bluetooth peripheral_esp sample, that builds and runs as expected using zephyr 1.13.99. Using 1.14, it builds correctly but crashes with the following message:

***** MPU FAULT *****
  Instruction Access Violation
***** Hardware exception *****
Current thread ID = 0x200022d0
Faulting instruction address = 0x200049a0
Fatal fault in essential thread! Spinning..

Before crashing it displays some expected sensor readings. It looks like Bluetooth fails completely.
Any quick hints on what might be the cause?
Thanks
