Detailed Description

Binary info is intended for embedding machine readable information with the binary in FLASH.

Example uses include:

• Program identification / information
• Pin layouts
• Included features
• Identifying flash regions used as block devices/storage

bi_decl

#define bi_decl

(

_decl

)

__bi_mark_enclosure _decl; __bi_decl(__bi_ptr_lineno_var_name, &__bi_lineno_var_name.core, ".binary_info.keep.", __used);

Declare some binary information that will be included if the contain source file/line is compiled into the binary

bi_decl_if_func_used

#define bi_decl_if_func_used

(

_decl

)

({__bi_mark_enclosure _decl; __bi_decl(__bi_ptr_lineno_var_name, &__bi_lineno_var_name.core, ".binary_info.", ); *(volatile uint8_t *)&__bi_ptr_lineno_var_name;});

Declare some binary information that will be included if the function containing the decl is linked into the binary. The SDK uses –gc-sections, so functions that are never called will be removed by the linker, and any associated binary information declared this way will also be stripped
