WeвЂ™ll be flashing in the boot mode (GPIO-0 to Gnd).

bin/at/, You should find a README.md that will show you the offsets of where each bin file is supposed to be flashed.

Next, Install the esptool.py python module.

So I had to go with the older 1.6.2 that supported a 512 KiB + 512 KiB map.Дownload your preferred firmware zip file, extract the zip file and navigate to. The ESP-01 by Ai Thinker only had 1 MB in total. ie, You need 2 MB of flash space on your board. The latest firmware at the time of writing this was 1.7.3 and as you can see from the description on the download page, that only supported a 1024 + 1024 KiB flash map. This requires some understanding of terminal and any wrong step here may brick your module. This the default tool which is provided by Espressif to flash firmware onto ESP chips. Using Esptool from the terminal (command line) After this, you can restart the ESP8266 after removing GPIO-0 from GND. After that press upload button as usual and your firmware will be flashed.

Now select the correct serial port and choose the Blink example.

The installation of ESP8266 in Arduino IDE is done.

Now close the Boards Manager window and select the Generic ESP8266 ModuleВ from the board selection list.

ClickВ the InstallВ button to install the ESP8266 Board.

Add the below-given link to Additional Boards Manager URLs.

For flashing official firmware head on to next method The Arduino method is only flashing the user-written firmware. There are 2 ways to flash your firmware, the First one is using esptool which is a bit complicated process and the second one is using Arduino IDE which also uses esptool at backend abstracting all its complexities. When we restart the module, this setup will put it into bootloader mode. To put ESP8266 into bootloader mode we need to first pull GPIO-0 to GND.

USB-TTL ( learn how to use Arduino as USB-TTL adapter).ESP8266 (obvious, but still needs a mention).We need below-mentioned hardware components:

This module has a powerful on-board processing and storage capability that allows it to be integrated with the sensors and other applications through its GPIOs. The other type by the generic manufacturers might just have 512 KiB flash (and their PCBs could be blue in color).Д®SP8266 comes pre-programmed with an AT command set firmware, meaning, you can simply hook this up to your Arduino device and get about as much WiFi-ability as a WiFi Shield offers. These have a flash memory of 1 Megabyte (aka 8 megabits). The AI-Thinker boardsВ have a black PCB with the words вЂњAI-CloudInsideвЂќ printed near the PCB antenna. So to simplify the whole process and understanding of putting your firmware on ESP8266-01 (by AI-Thinker), we are writing this article. But sometimes it becomes a bit tedious task to flash your firmware onto it. 5v logic level of RX and TX pins from Arduino UNO didnвЂ™t fry the esp8266.We know that ESP8266-01 is an impressive, low cost and powerful module with networking capabilities.вЂ“ IDE canвЂ™t communicate with esp8266 module Use 3.3V logic for RX and TX pins of esp8266 (cp2102 module).Recommendations, Problems and their Solutions: Click Upload.Дisconnect GPIO0 from the ground to exit from flash mode. Change board to Generic ESP8266 module: Tools > Board > Generic ESP8266 module. Change pin 13 to pin 2 (GPIO2 of esp8266). Use example sketch from Arduino IDE: File > Examples > Basics > Blink. Go to Tools > Board > Boards Manager and install esp8266 by ESP8266 Community. Update board manager by adding the URL below in Arduino Preferences: File > Preferences. Connect GND pins of ESP8266 and CP2102 (if something goes wrong).Connect GPIO 0 to GND when flashing or uploading program from Arduino IDE.Occasionally connect RST to GND to solve espcomm_sync failed.Connect a resistor between Vcc and CH_PD вЂ“ pull up resistor (tried values: 1k -3.3k).* ESP-01 variant (black) bought from CircuitPortal.
