Root Cause

External crystal or PLL failed to stabilize.

generic

Workarounds

  1. 85% success Check crystal connections and load capacitors
  2. 82% success Fall back to HSI (internal RC) and verify with scope

Dead Ends

Common approaches that don't work:

  1. Switch to maximum PLL frequency immediately 85% fail

    Exceeds chip spec, unreliable operation

  2. Ignore clock failure and continue 88% fail

    Undefined behavior, wrong timings
