ESPEasy - Flash Failed

[onlize]

Hello,

I am trying to flash firmware and it is failing. I connected a UART (USB->TTL) converter to my nodeMCU. I connected the white cable (TX) to the RX pin and the green cable (RX) to the TX pin. Also, I connected the black cable to the GND pin of my nodeMCU, and I connected power supply to the nodeMCU.

I know that my UART (USB->TTL) converter works because I often use it with Raspberry PI boards during setup.

Can someone help me? When I try to flash the firmware, I have the following:

trying to connect
flush start
setting serial port timeouts to 1 ms

A node MCU?
It has flashing adapter on board so I'm not sure if an external UART
will work at all or not as the internal UART might block it.

You may just use an USB cable to flash a nodeMCU.
Usually they use a CP2102 (little square chip) or a CH340G (rectangle chip) as an UART.

That works quite well wihtout any button pushing as setting flashmode is done automatically.

Thank you for your reply.

Sorry, I am very new to this. What does it mean :

Is it a special cable?

Thank you.

I was able to install it. Thank you for your help.

These are the UART chips on the nodeMCU.
You should know the chip type as not all windows versions do have driver for these chips out of the box.
