I know that there are a lot of similar topics but i couldn't get any useful info

I'm trying to upload a "basic" sketch with blinking built-in LED

When i press "upload" it shows

Upload started

avrdude done. Thank you.

When i open up the debug window in arduino agent it shows a lot of similar outputs:

Serial Ports:
[
{
"Name": "COM4",
"SerialNumber": "A50285BIA",
"IsOpen": false,
"VendorID": "0x0403",
"ProductID": "0x6001"
}
]

{
"Msg": "avrdude: stk500_recv(): programmer is not responding",
"ProgrammerStatus": "Busy"
}

{
"Msg": "avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0xa6",
"ProgrammerStatus": "Busy"
}

I don't like lines "Serial Ports ... COM4 ... IsOpen: false" and "ProgrammerStatus Busy" maybe it is the source of my issue?

Or maybe i do it the very wrong way and i need to plug some programmer and flush arduinos firmware to make it work. I'm novice in electronics, could you please answer in detail what should i do and where everything is placed? I tried to connect "res" with "gnd" and "tx" with "rx" and made sure that loopback works and i don't know what to do then

What is the exact model of your board?

3

It's a clone of Arduino Uno, i also tried with a clone of arduino pro mini. The same results for both

4

This is not an answer. Arduino clones are different. USB-UART bridge can be on Atmega 16U2, CH340G, CP2102. What is yours? Give at least a good photo of the board.

5

A little thing on the UNO board says it's CP2102

The kind of main chip of this board is Atmege328P-PU

Arduino pro mini is connected with that thing

Sorry, because i'm a new user on the forum so i can't post images right away (and post more than 2 links)

That looks funny for an Uno. 115200 would be the normal speed.

Your board has CP2102 USB-UART bridge. You need to install appropriate driver. I use driver from Keyestudio PLUS board KS0486_Keyestudio_PLUS (with detailed installation instruction) or original driver from Silicon Labs. After successful installation you will see Silicon Labs CP210x USB to UART Bridge (COMxx) in the Device Manager with your COM port number. Then choose Arduino Uno board in Arduino IDE, your COM port number, blink.ino, Verify, Upload.
I have not seen a board like this. If you have a complete photo of your board, I will be grateful.
If your board is Ваниль, no photo needed.

I already had that driver installed. When i toggle "show hidden devices" in windows device manager it shows
image
When i plug the device in any usb port it shows "USB Serial Port (COM4)" non grayed-out but COM3 remains grayed out
Am i doing something wrong?

10

Ok, i'm trying with UNO and "Silicon Labs CP210x ..." is shown as active in device manager
image
But i choose correct Port in arduino ide, correct device (Uno) and the same errors occur

11

Hidden devices are those devices that were previously connected (ghost devices). Silicon Labs CP210x USB to UART Bridge (COMx) should appear when Arduino is connected (not grayed). If this is not the case, you need to reinstall the driver. Read Installing Driver here.

12

I reinstalled the driver and nothing changed

13

I just tried to upload the sketch on linux machine (ubuntu) and there are the same avrdude: stk500_recv(): programmer is not responding errors. Maybe something wrong with my boards?
