@ -17,3 +17,12 @@ Next code selectes canned symtab from application:
#include <nuttx/binfmt/canned_symtab.h>
...
canned_symtab_initialize();
The option can have substantial effect on system image size, mainly
code/text. That is because the instructions to generate canned_symtab.inc
above will cause EVERY interface in the NuttX RTOS and the C library to be
included into build. Add to that the size of a huge symbol table.
In order to reduce the code/text size, you may want to manually prune the
auto-generated canned_symtab.inc file to remove all interfaces that you do
not wish to include into the base FLASH image.
