I followed the steps provided in the steps to flash Espruino on ESP 8266 using esptool.py . I am unable to flash and i am getting fatal error continuously.
WARNING: Flash size arguments in megabits like '4m' are deprecated.
Please use the equivalent size '512KB'.
Megabit arguments may be removed in a future release.
Serial port COM3
A fatal error occurred: Failed to connect to Espressif device: Timed out waiting for packet header
I am trying from windows 10 PC connecting through COM port.
As any fyi - I successfully flashed espruino into nodemcu in past, but i am failing in arduino UNO model.
Please provide pointers to me. If it is not possible then please let me know, so that i won't try.
Quite a confusing post... ;-) ... could you please make a picture of your setup and upload it?
I'm afraid if you are using an Arduino UNO, those do not use an ESP8266, or in fact any chip capable of running Espruino - so I think you're out of luck.
Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.
