I use the CH340 USB to serial driver (COM5:)
I've installed python and esptool.py. I've used this to flash ESP8266 boards for microPython and that works fine.

PS C:\Users\me\OneDrive\Documents\esp8266\ESPruino> puttyFrom putty I am trying to connect to the board directly with 115200 baud and then I power cycle it and try again. After that I attempt the Espruino Web IDE with 115200 baud.
I have also tried this esptool.py line:
python ..\code\esptool\esptool.py --port COM5 --baud 460800 write_flash --flash_freq 80m --flash_mode qio --flash_size 4MB-c1 0x0000 "boot_v1.6.bin" 0x1000 espruino_esp8266_user1.bin 0x3FC000 esp_init_data_default.bin 0x3FE000 blank.binwhich flashes the board, also tried this one:
python ..\code\esptool\esptool.py --port COM5 --baud 115200 write_flash --flash_freq 40m --flash_mode qio --flash_size 4m 0x0000 "boot_v1.6.bin" 0x1000 espruino_esp8266_user1.bin 0x7C000 esp_init_data_default.bin 0x7E000 blank.binbut that one says: Detected overlap at address: 0x7c000 for file ...
I have tried these versions, in order, with both working esptool.py lines above:
1) https://www.espruino.com/binaries/espruino_1v99_esp8266_4mb/
2) https://www.espruino.com/binaries/espruino_1v99_esp8266/
3) https://www.espruino.com/binaries/espruino_1v98_esp8266_4mb/
4) https://www.espruino.com/binaries/espruino_1v95_esp8266_4mb/Still no console in putty or the Web IDE

It is an AI Thinker ESP-12F (ESP8266) device. Do the flashing addresses match this device? How can I find out what the addresses should be?
-
I am using Windows 10 and tried a serial connection in putty every time as well after flashing the device.
Yes I verified the baud rate both in the Espruino web ide and in putty.
And after every time I flashed the device I tried to connect with both the web IDE and a serial connection in putty and then power cycle the device (disconnect from the usb). Still nothing. I am assuming that I am getting the wrong addresses in the flashing process but I have tried every set of addresses I have seen. I have not tried to downgrade the version though. Will try that. -
Hi, I am brand new at this.
I can't get started. Flashing seems OK, well from esptool.py point of view.
My board says ESP-12F and ESP8266MOD on the chip.
I have tried all flashing versions of the readme file in both espruino_1v99_esp8266.tgz and espruino_1v99_esp8266_4mb.tgz. I just do not know what more to try.The Espruino Web IDE says everytime I've flashed and tried connecting (using 115200 baud):
Unable to retrieve board information. Connection Error?
Connected to COM5 (No response from board)What else can I do?
Finally got it!!! YiiiiiHaaaa!!!!
