Virtual Flasher

Flash memory access is emulated using SPI Flash, and this Component implements make targets to operate on the flash backing file in a similar way to flashing a real device.

The following options are interpreted and used to provide command-line parameters to the emulator executable:

FLASH_BIN

Full path to the flash backing file

HOST_FLASH_OPTIONS

This defaults to a combination of the above variables, but you can override if necessary.

There are additional settings defined in the Esp8266 Esptool.
