I have a few questions regarding ESP8266
- Can I flash AT firmware on a ESP8266 board?
- I compiled the esp8266 blink example. When I performed the ESP8266 sketch data upload from the Arduino IDE, i got the error SPIFFS error: esptool not found. How do I install the esptool? My version of ESP8266 is similar to Wemos D1 mini. It has the ESP8266, a led and an antenna.
- I flashed the AT firmware that I used for ESP01 onto the ESP8266. When I open the serial port on the Arduino IDE, the baud rate of the serial port is 74880 instead of 115200. It has these error messages, error magic! backup boot failed.
- i also having trouble finding a site that I can download the Nodemcu firmware that I can use to flash.
For the SPIFFS problem, I think this solves the issue: https://www.esp8266.com/viewtopic.php?p=82520#p82520.
As for the other questions, I didn’t understand… What AT firmware are you talking about? Can you be a little more specific?
For the AT command firmware, I am referring to the “esp8266_nonos_sdk_v1.5.4_16_05_20” that I can download from the espressif.com site.
Can you provide a link where I can download the Nodemcu firmware?
Many thanks for your help.
If you are referring to the “original” ESP8266 AT firmware, as you said, you can download it from espressif website:
However, if you are referring to the ESP8266 NodeMCU LUA firmware, I think this is what you are looking for:
Let me know if this is what you were looking for.
Yes, this is what I am looking for. For the Nodemcu, do I select what drivers to include in the build and should I pick the release version ot the frozen version? Thank you.
