debug_build_flags
Type: String
| Multiple: Yes
| Default: -Og -g2 -ggdb2
These flags/options affect the preprocessing, compilation, assembly and linking processes for C and C++ code.
Note
This option might be helpful to adjust the optimization level if firmware with debug information is too big to be uploaded to a target
Example
[env:debug]
platform = ...
board = ...
; Set optimization level and amount of debug information generated by the compiler
debug_build_flags = -O0 -ggdb3 -g3
Other possible flags that might be useful for debugging your application.
