Unable to upload sketch - Arduino mega 2560 Pro

Development Tools IDE 1.x
1

Hi,
I wanted to upload my program to the Arduino mega 2560 Pro with the Arduino IDE.

  1. In contrast to the Mega 2560 R3 the IDE shows a different port, namely ttyUSB0 instead of something like ttyACM0.
  2. The Board section of the IDE has no Mega2560Pro, only "Arduino/Genuino Mega or Mega 2560"

When choosing "ttyUSB0" and "Mega or Mega 2560" I get the following error statements (avrdude):

avrdude done.  Thank you.

Something goes wrong. But what?
Any idea?
Thanks

Hello @r_a_mueller

It appears that the 'Mega Pro' you acquired is not an official Arduino product.

This is the reason why Arduino IDE is not detecting your board.

We recommend to take a look at our official online store and only buy from us or official distributors to ensure you get genuine Arduino products.

store.arduino.cc

I know that it is not an "official" Arduino. I first worked with an Mega 2560 R3, but this Arduino is too large. One of the smaller Arduinos I'm familiar with (nano, Mini Pro) doesn't have more than one serial port, I need three of them.

No one ever used this Mega 2560 Pro?

That's plain wrong. There are plenty clones that are detected without issues or.sometimes just require a driver.

Useless comments like these don't help and can be considered spam.

Wenn in der Anzeige "USB-UART-Adapter CH340" steht, benötigst Du den passenden USB-Treiber für Dein Betriebssystem.

Sorry for German.

That's what the manufacturer/vendor (Eiechip Official Store) writes:
"Sorry my friend. We do not provide product information at the moment." Not really helpful :slight_smile:

My OS (Linux) provides the driver for CH340 in the kernel. I never needed to install a driver of that kind. The board we're speaking of has a CH340G chip.

I think the problem is not a lacking driver. The last lines of the error message (see my first post):

avrdude: verification error, first mismatch at byte 0x0d6c[color=#222222][/color]
         0x60 != 0xe0[color=#222222][/color]
avrdude: verification error; content mismatch

I think that's where the dog is buried ... (leo.org says: That's the crux of the matter)
