Arduino UNO - Mac OS 10.7.5 - Not able to upload

Greetings all,
I’ve just got my UNO R3 board and I’m looking forward to start using it. However, it’s being a pain to get it working on Mac.

I have a Windows 7 PC and the board worked perfectly so this is not an issue with the board/USB cable.

Here is my history – Trying to get it working on Mac OS:

  1. There was no device under “Tools >> Serial Port” – Fixed downloading FDTI drivers, now I can see “/dev/tty.usbmodemfa131”

  2. Now when I try to upload the “Blink” sample, I get “avrdude: stk500_recv(): programmer is not responding” – I’ve tried to create /var/lock and give it 777 permission but it didn’t work.

Any thoughts?

Thanks a lot for any advice.

I am in the 'same' boat as you.

I thought it was the FTDI driver, but I received an email from a technical support engineer from FTDI and he said that Mac's working with an Arduino Uno do NOT need an FTDI driver.

FYI, I still have not gotten my USB port to communicate with Arduino Uno. My goal is to get "blink" to work from my Mac (OS=10.7).

Any suggestions would be greatly appreciated.

According to some docs I've found here we don't need FTDI for Uno R3 but I've installed it anyway.

It is sad to see that on Windows the installation was smoothly but in Mac it sucks :frowning:

Well.. let's continue digging...

Which Arduino IDE Version are you using?

My Setup:

OS X, 10.8.4
Arduino IDE 1.0.5

No issues.

  • OS X 10.7.5

  • Arduino IDE 1.0.5

  • FTDIUSBSerialDriver_v2_2_18

  • MacBook Pro (no OS updates - just checked).

I didn't need a driver for my Mac mini, 2.4 GHz Intel Core 2 Duo.
So I'm not sure whether this may make a difference.

I would try:

  • uninstall the FTDIUSBSerialDriver
  • quit Arduino
  • delete the file: /Users/yourusername/library/Arduino/preferences.txt
  • start Arduino again

I'm trying to remove the drivers, but I don't know how to do it on Mac. Do you know?

It should be in the folder /System/Library/Extensions

I never uninstalled a driver, but I think you can just delete the file. You may consult the FDTI documentation to be sure.

If you required the FTDI drivers, you don't have an actual Uno R3. Where did you buy it, Fry's? If so, select Duemilanove in the board menu, not Uno.

I've bought it from DX (china). It is not a original Arduino board.

The weird thing is that on Windows it works fine (without having to add drivers).

I'll try to change my board as you've suggested.

Thanks,

Unfortunately it didn’t work. I’ve tried all Duemilanove boards available in the tool, but none have worked ?

I had also removed FTDI drivers and plugged Arduino back, expecting Network Preferences to show, no luck though ?

What do you get with ls -l /dev/cu.* ?

As an example for a Mega 2560, no Arduino connected:

$ ls -l /dev/cu.*
crw-rw-rw-  1 root  wheel   33,   3 10 Aug 14:42 /dev/cu.Bluetooth-Modem
crw-rw-rw-  1 root  wheel   33,   1 10 Aug 14:42 /dev/cu.Bluetooth-PDA-Sync

Arduino connected:

$ ls -l /dev/cu.*
crw-rw-rw-  1 root  wheel   33,   3 10 Aug 14:42 /dev/cu.Bluetooth-Modem
crw-rw-rw-  1 root  wheel   33,   1 10 Aug 14:42 /dev/cu.Bluetooth-PDA-Sync
crw-rw-rw-  1 root  wheel   33,  23 20 Aug 07:55 /dev/cu.usbmodem411

Hi

With Arduino connected to my Mac I can see /dev/tty.usbmodeXXX (but it appears only after I've installed FTDI drivers).

Any other thoughts?

The FTDI drivers had nothing to do with it. FTDI devices show up as "usbserial", not "usbmodem."

Don't worry though. Contact Deal Extreme. I'm sure their technical support team can help.

Thanks James, I was not aware that DX had a Tech Team to support customers.

Anyway, I not confident anymore... I guess I'll have to keep windows to do any development with Arduino.

Hi Guys, me again.

I was not able to have MAC working with my board so I installed boot camp and a Windows 7 into my MacbookPro.

Once booted in Windows, I’ve connected my board to my notebook and the driver was properly installed.

However I’m still not able to upload the program to the board. I get this error “stk500_getsync(): not in sync:”.

Any ideas?

Thanks.
