That’s because you need to flash SPIFFS as well!
Update esp8266 firmware using arduino update#
Update 1: This updated the binary firmware, but does NOT upload any data files (e.g., the HTML and Javascript files). I don’t think you can cause any problems that you can’t recover by flashing the ESP8266 again with good firmware, but I am not certain. Observe the change you made as it is reflected in the wifi webpage or functionality.Īgain, BE CAREFUL. It’s time to reset and/or power cycle the Star OTTO and try again. If you get messages like these: : No Answer When you flash over the network port, it does the following: Uploading.
Update esp8266 firmware using arduino serial#
Also, if anything goes wrong you’ll need the serial method so learn that first!Īs above, make a tiny change to the build date. While this works, it is rough around the edges.
did it change to what you changed it to? If so, that tells you it worked!įlashing the ESP8266 via the network port (quirky): Notice the version number and date in the lower left…. Observe the Star OTTO’s wifi welcome page (refresh it – you might need to open it in a new browser instance).
Update esp8266 firmware using arduino manual#
Sometimes it all “just works”, sometimes it needs that manual intervention.) (Note: Even just holding the “ESP B/L” button and resetting the board seems to do the trick… I suspect it’s a Windows thing, as the ESP32 is a tricky board to codeload as well on Windows. To force the ESP8266 into bootloader mode, unplug the Star OTTO, hold the ESP B/L button, plug the board back in, and release the ESP B/L button – the ESP8266 should now be in its bootloader mode, while the Star OTTO itself should be in normal mode, with the recovery script running. If it fails to flash, check your settings. The fields are fixed-length and weird values can surprise you later with weird behavior from apps that depend on them (especially the version number).Ĭompile and flash the firmware over serial – it should work, and no weird errors either. Uncomment the following line in config.h: #define STAROTTOįor the purpose of seeing things work, change the BUILD_DATE value in config.h slightly. Load up ArduinoFirmwareEsp.ino and target the ESP8266 Arduino device via serial (The key here is that the codeload for the Star OTTO using EspRecovery will expect a 230400 baud rate). Note: In EspRecovery.ino, we see SerialWiFi referenced… which is defined in arduino-library-wifilink/src/utility/uart/serial.h as an alias to Serial.
Update esp8266 firmware using arduino install#
Install the WiFi Link library via the library manager (1.0.1 or later)īuild WiFi_Link\examples\Tools\EspRecovery.ino for the Star Otto and flash it normally. If Wifi isn’t working right, this is the only easy way to fix things. Port: the serial port (preferably) or the network port for the OTTOįlashing the ESP8266 via the serial port (preferable!): Upload speed: "230400" (for serial recovery) or "9600" (for network port) The other settings should be as follows: Board: "Arduino" In the board manager, under “ESP8266 modules”, select board “Arduino”. Once that’s all installed, restart the Arduino IDE. (I tried installing the Boards Manager version of the library and that was too out of date for this.) In a nutshell: cd hardware Next, install the very latest ESP8266 hardware library for Arduino, per the instructions for doing it via Git. As for Python, it claims to need 2.7 but I used 3.6 and it worked fine. I’ve had some problems with 2.13.0 though, so you might have better luck with 2.11.1. More on that below…įirst, install the Arduino 1.8.2 (or later) IDE (I don’t think it really matters if it’s the. In fact, it appears the Serial device is what talks directly to the ESP8266. In my previous post I noted that the terminal serial device for the OTTO is SerialUSB, not the usual Serial. Here’s a close-up showing the OTTO’s master reset button, the ESP8266 module, the ESP8266’s bootloader button (“ESP B/L”) and the OTTO’s bootloader button (at the very bottom).

As I’ve found two important bugs so far, I decided the first order of business is to learn how to modify it! The Arduino Star OTTO has an Espressif ESP8266 on board.
I make codeloading FUN!!”īeware: There be dragons here! While this information should enable you to recover even if you screw up the ESP8266 firmware, I can’t guarantee that will always work (though I am far more confident now that I have serial recovery working…) “An ESP8266? That’s easy! Feel free to follow along with my simple step by step instructions.
