- For an ESP8266 with 8 Mbit / 1 Mbyte flash, configure the ESP8266 Download Tool according to the information from the README.md file like below. Some deduction must be done, to find the correct files: For an ESP8266 with 16 Mbit / 2 Mbyte flash, configure the ESP8266 Download Tool according to the information from the README.md file like below.
- When flashing 4 files are needed (at least if you flash original Espressif flash firmware): bootv.x.bin (x to be replaced withwhatever applicable) espinitdatadefault.bin. Userx.1024.new.2.bin (x to be replaced withwhatever applicable) blank.bin. Each file needs to be flashed in its proper flash memory location; see file in this step.

Aug 15, 2018 This blog explains how the download tool does with the secure boot and flash encryption. But I still got confused. Cause generating and burning key with download tool is very different from the IDF instructions More instructions or examples of using secure boot & flash encryption with the download tool are very welcomed. 690 Bibo Road Block 2 Suite 204, Zhangjiang Shanghai, China.

How do you completely erase ESP32 flash chip using Flash Download Tool? This has been tricky for a long time (LONG time, especially in case of the ESP8266). This has been made simple in the latest version of the Flash Download Tool.
This version of the Flash Download Tool comes with a simple “Erase” button. This lets you completely erase ESP32 flash memory.
This is something you should do every time you get a fresh ESP module and plan to run your own custom firmware on it.
Note that we are not providing a link to the new Download Tool because the link changes rather frequently. You can find the Download Tool on Espressif’s official website. The one download tool supports all of Espressif’s chips (ESP8266 and variants as well).
It would probably be a good idea to select the flash size manually rather than just rely on the automatic size detection. Murphy loves ESP developers most!

- Crystal Frequncy choices: 40Mhz, 26Mhz, 24Mhz – For a 40M crystal , the booting uart tx baud is 115200,(74880 for 26m accordinglyCrystal Freq will be set to the BYTE[48] of esp_init_data_default.bin
- SPI Flash speed: 0 = 40MHz , 1 = 26.7MHz, 2 = 20MHz, f = 80MHz stored in BYTE[3]&0f of the images
- SPI flash read mode: 0 = QIO, 1 = QOUT, 2=DIO, 3=DOUT set to the 3rd BYTE at flash address 0x0 so it is BYTE[2].
- Flash size: Flash size is SET to the higher 4bit of 4TH BYTE at flash address 0x0 which is BYTE[3]»4)&0xf in the image:
0:512KB(256KB+256KB) – 4Mbit
1:256KB – 2Mbit
