I have this error while uploading new snippet on arduino nano clon

can someone help me

[Juraj]

in Tools menu try to change the Processor option

[dunaverde]

stll not working )-: it is susposed to be ATmega328p (old bootloader)
also only one led is on (pwr) and px is often blinking

Is your Nano detected correctly as a COM port on your system?

Can you post a photograph of your Nano clone?

[dunaverde]

yes

the com3 is arduino

@dunaverde

px is often blinking

If you mean the second LED from the top in your photo, and the blinking occurs regularly as you try to upload code to the board, this means that at least you're getting some data across through the USB-UART interface.

Has this Nano worked before?
If you have an ISP programmer (USBASP or a second Arduino board you can use as ISP programmer), you could try re-programming the Nano using that approach. Perhaps reprogramming the bootloader will help.

[dunaverde]

the led above the pwr led blinks rapidly for about 0.3 seconds. This is my first and only arduino so I can't reprogramm boot.

[xfpd]

The rapid blinking is the MCU looking for data to upload... if the MCU sees no data to upload (maybe due to bad connection), it starts running whatever is in memory.

@dunaverde

px is often blinking

This would be the code stored in the MCU. If the "L" LED is blinking, that is probably the "blink" sketch. If the TX (there is no PX) is blinking, that is probably a "Hello, World!" printing to the Serial Monitor.

Verify...
IDE >> TOOLS >> PORT >> your port
IDE >> TOOLS >> BOARD >> ARDUINO AVR BOARD >> your board

The Device Manager looks like you have a non-CH340 USB.

Also verify your USB cable is a DATA cable and NOT a power/charging cable.

@dunaverde

ATmega328p (old bootloader)

This is probably the wrong choice. Choose the other.
