Arduino RF-NANO upload issue

Dear, Arduino forum
currently, we are having a critical issue with RF-NANO Arduino,
we have two RF-NANOs that were transmitting the data and one was receiving the data.

  1. This was working fine, however after updating the IDE, since then everything was malfunctioning.

  2. code can verify, but I cannot upload it. When I tried to upload, but it was giving this error message

  3. I tried installing the older version, which is Arduino 1.8.18, and tried the newer version 2.0.4, however, they were giving out the same error

  4. when I tried to upload the code, it was indicating that

Would you please help us to fix this issue, this is very critical to our research,

Thank you for your concern and support,

If you're RF-Nano board is based on a Nano Every (the category you posted in), it looks like you selected the wrong board.

If the board that you're using is based on the 328P (I think the RF-Nano is; post a link to the product), try the different options under tools -> Processor.

Does COM10 disappear from Windows device manager when you disconnect the board?

Hi Thank you for the reply,
I have chosen the processer as ATmega328P (Old bootloader),

I also have tried the other boards, such as

  1. Arduino Nano
  2. Arduino Nano every
  3. Arduino Nano 33BLE
  4. Arduino Nano RP 2040 Connect

for the port COM 10 is always there, but once I upload, after few minutes of waiting,
that error message is indicated.

Could it be the IDE version could be the issue?
hardware seems to work fine.

If COM10 is there when your board is disconnected, it's not the Arduino.

I mean when the Arduino is not connected, there is no COM 10, and when connected I can see the COM 10 in the port, so I am positive that it is the arduino.

I am confused that if RF-NANO is not compatible in the most updated version or why does this message

comes out?

It should have been.

Anything connected to pins 0 and 1?
Anything else connected to the boards?
Did you try to re-install the drivers?

And I think that I'm out of options after that.

Because I'm quite sure that your board has a 328P processor, I have moved your topic to a more suitable location on the forum.
