ESP_HexFlasher this is a tool for flashing ESP8266 firmware in Intel hex format.
Such firmware consists of one file with the hex extension, containing all the data. This is better than a few bin-files that you can mistakenly flash to other addresses or forget to flash some.
The hex format does not have these disadvantages. It is very easy to create a hex file if you have an elf file. For this, the objcopy component from GCC is used.
Tool ESP_HexFlasher compiled for operating systems Windows, Linux and MacOS X and you can download it in the attachment to the message.
An animated gif-picture shows the flashing process.
Checkbox Clear system memory needed to write data by default to the system areas of flash memory. This may be needed if the ESP8266 does not work, but sends something like this to the UART.
Button Export converts hex file to bin files.
For example, the HEX.zip archive contains standard AT firmware and Blink (using GPIO2) in hex format.
