Detailed Description

Constant symbols are unchangeable named memory addresses.

Symbols may be named function or global objects that have been exported for linking. These constant symbols are useful in the base image as they may be placed in ROM.

Note

When updating this structure, make sure to also update the 'scripts/build/llext_prepare_exptab.py' build script.
