Uploading firmware to ESP8266

Open FerronN opened this issue 2 years ago • 2 comments

Describe the bug I'm trying to flash the nodemcuv2-ir onto the ESP8266, but it stop after initializing. The LED flashes (erase flash), but after that nothing happens.

To Reproduce image

The COM port driver is installed. I uploaded some code with the Arduino IDE to the ESP8266 and that works without any problem. So I think it's not the device or some driver.

Expected behavior Upload firmware

Do you reproduce on several ESP8266 ?

No, because I only have one. I now managed to do it with NodeMCU-PyFlasher. But I had to change the flash mode to DOUT. On the website you can't choose the flash mode, so maybe the site uses DIO? I couldn't find the scirpt that's running.

Here is the script https://github.com/1technophile/OpenMQTTGateway/blob/development/scripts/gen_wu.py Not sure we detail the flash mode
