Root Cause

Static RAM usage exceeds chip SRAM capacity.

generic

Workarounds

  1. 85% success Reduce global/static variable sizes, use dynamic allocation carefully
  2. 90% success Use const for lookup tables to place in flash, not RAM

Dead Ends

Common approaches that don't work:

  1. Increase stack/heap size 88% fail

    Worsens the overflow

  2. Move everything to flash 82% fail

    Only const data can go to flash
