Esp8266 ESP-01 simple sketch fails to upload

Solved

Hi there,
I’m having troubles with my setup:
I am using an ESP8266 ESP-01 module with USB2Serial CH340G based adapter (see below).

and when I try to upload my sketch (which is the Blynk ESP8266_Standalone Example):

#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

char auth[] = "YourAuthToken";
char ssid[] = "YourNetworkName";
char pass[] = "YourPassword";

void setup()
{
  Serial.begin(9600);
  Blynk.begin(auth, ssid, pass);
}

void loop()
{
  Blynk.run();
}

I get :

The configuration is:
OS: Windows 10 ON VIRTUAL MACHINE
Board: Generic ESP8266 Module
Flash Mode: QIO
Flash Size: 512K (no SPIFFS)
Debug port: Disabled
Debug level: None
IwIP Variant: v2
Reset Method: ck
Crystal Frequency: 26MHz
Flash Frequency: 40MHz
CPU Frequency: 80MHz
Upload speed: 115200

And I installed the:

  • ESP8266 Board from the Board Manager
  • Blynk library from Library Manager

AT COMMANDS ARE FULLY WORKING.

I seriously don’t know how to fix this.
Thanks in advance.

The Blue LED on ESP responds somehow, when You try to upload?

3

Yes of course:
When the Arduino IDE finishes compiling (so it starts to upload), the blue led blinks EIGHT TIMES (~1Hz blinking)
before the first error: failed reading byte comes out on the debug output monitor.

I think that LED blinking coincides with error: failed reading byte outputs number.

I’ve seen a thread somewhere on here where a person was having a problem with those USB programmer boards.
Do you have a regular FTDI programmer that you could use instead?

Also, is QIO the correct programming mode?

Pete.

Then it might be, this board is unable to switch ESP into FLASH mode…

7

No I don’t… I bought this on eBay (actually two of them, to make sure that - at least - one of them worked) for a really cheap price 2€/piece.
Should I buy a FTDI Board instead?

How do I check the correct programming mode by the way?

8

You mean to switch the CH_PD “mode”?

9

No, CH_PD is a “Switch ON” of the ESP. IF Blue light flashes, and IF AT comm is working, then IT IS pulled low properly. What I mean, is pulling the GPIO0 LOW, AND apply RESET.

And CH340 works with ESP (as - I think - every other USB-UART converter). The problem might be it’s wiring (the companion board)

And this is, what I have found: http://www.arjunsk.com/iot/programming-esp8266-esp-01-using-esp8266-programmer-ch340g-chip-adapter/

The solution you linked and described might be the right one.
I’ll reply later telling you if it works.

I’m almost sure it is :wink:
In the meantime you should change the flag from issues and errors to problem with my project. Or @Gunner will certainly do it for you :smile:

This is the thread I was thinking of:

AND THAT’S A YES!
You saved my day and now I will be able to do the thesis of maturity!

Thank you so much.
