By default, the application is built as a binary file in a format compatible with

the ESP32 bootloader. In addition to this application, 2nd stage bootloader is

Note that at the moment, ESP-IDF does not contain all the startup code required to

initialize the CPUs and ROM memory (data/bss). Therefore it is necessary to execute

CONFIG_APP_BUILD_TYPE_ELF_RAM is required, other options help reduce application
