This is no longer required since the functions automatically get pulled in based on the usage. A quick summary of footprint comparisions before and after these set of patches is shown below: Hello-World: (simplified for readability) old Total image size:~ 104902 bytes (.bin may be padded larger) old Total image size:~ 105254 bytes (.bin may be padded larger) Per-archive contributions to ELF file: Archive File DRAM .data & .bss IRAM Flash code & rodata Total old libesp32.a 1973 177 4445 3939 2267 12801 new libesp32.a 1973 185 4473 3939 2267 12837 new libnvs_flash.a 0 92 0 274 8 374 new libstdc++.a 0 0 0 24 0 24 For some reason, nvs_flash.a (~400bytes) gets pulled in (particularly the nvs_flash_init() function). Power-Save: (simplified for readability) old Total image size:~ 421347 bytes (.bin may be padded larger) old Total image size:~ 421235 bytes (.bin may be padded larger) old libtcpip_adapter.a 0 81 0 1947 115 2143 new libtcpip_adapter.a 0 69 0 1897 115 2081 The size actually shrinks a bit, since the AP interface function doesn't get pulled in.
