Mega 2560 - FTDI possibly not working...

Hey Forum!

So... after getting my board out of the dust I was trying to upload a little test sketch. But after getting an error message. I tried 'lsusb' on linux which didn't show my board so I thought it might be broken... Today I tested it on a windows machine and same problem... The sketch won't upload...

avrdude: stk500v2_command(): unknown status 0xc8
avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.

avrdude: stk500v2_command(): unknown status 0x01
avrdude: stk500v2_disable(): failed to leave programming mode

That's the error message on windows. When I plug in my board windows won't recognize it so I installed the driver manually. Same result.

I'd really like to programm my Arduino so I'd be really pleased if I got an answer soon :slight_smile:

The Mega2560 didn't use a FTDI chip. It uses an ATmega8u2 as the usb-to-serial adapter, which should appear as a usbmodem on to your operating system.

Hmm.. Ok thanks :slight_smile:

But still won't recognize the device

Could it be a driver issue on both operating systems?

Or can I buy a device to replace the old chip?

On linux when you attach the device, you should see something logged to dmesg. If not, the serial-to-usb converter may not be working.

Well.. Nothing arduino or USB relevant logged to dmesg...
So what do I look for to replace the old chip?
Thanks so far :slight_smile:

I'd try a different USB cable first.
