avrdude: AVR device not responding

[javiercuellar]

Hi

I have a Irduino Uno and a Irduino Yun Shield.
I am able to upload a sketch to the UNO.
I am able to connect to to the Yun Shield over the browser. Arduino Uno w/ATmega328P is selectecd for board type.


My problem is that using Arduino IDE to upload a sketch when UNO and Yun Shield is not posible. IDE is able to see Yun Shield on PORT menu, and BOARD I select "Arduino Uno -- Iduino Yun".

Always this message

avrdude: AVR device not responding
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.


I tried uploading new firmware to version 2.0.5 but same problem.
I know this is known issue because of link below, but I'm not able to fix it. Please help.

PD. I tried with 2 differents Iduino Yun Shield and same problem.

don't know if this can help you or not..

Thanks, but nit didn't help.

How can I test the SPI interface??

Hi

An update after hours of testing.

If I updoad the Bridge example directly to UNO (without shield), turn off, plug Yun Shield, turn on... it will work!!!
So, both cards work porperly.

My problem is that I cannot upload a sketch over wifi.
The new firmware 2.0.5 has an AUTODETECT AVR PART but it just says "unknown".
BTW.... yes, I shortcut jumpers on UNO to put mega16u2 under reset mode.

Any help??

Thanks

I had the same problem, you PROBABLY have either Uno board version v1 or v2, or some compatible board. I had a v2 board, and the problem is this :

Basically, you need to connect to ssh of Yun shield, and set all those GPIO ports on HIGH ( so, dont copy/paste LOW line).

When you did that, use multimeter on ICSP port and test the voltages. Since you put all ports on "high" , everything should be 5V.
Mine had 2.7V on one pin, and that's exactly the problem.

The thing is , Arduino Uno R3 has solved the voltage drop from LED13 (led on pin13), while R1 and R2 have that problem.

The solution for that problem is , desolder that LED from the board. No voltage drop.

Code: Select all

The solution for that problem is , desolder that LED from the board. No voltage drop.

YES!!!!!!!!!!!!!!!

Thanks a lot Brianbug. That work perfect!!!!

Hi I have bought one of you shield and cant get sketches uploaded. I have tried removing the led connected to d13 and still no success. I ssh into the shield and use the commands to get the voltage and they are not 5V even after I have removed the Led. If I connect 5 volts on VIN and a ground the voltages still don't match with no arduino attached. Does that mean the shield is defective? BTW I have tried two different clone shields. Both work when sketches are uploaded to Uno.

Hi guys. I found this thread to be quite helpful. I had a similar problem with my Dragino YUN/Arduino UNO boards. Was able to configure the Dragino and connect via wifi, but unable to consistently load skethes to the UNO.

Was able sometimes to load a sketch after a reset, but only once. After that would get the rc=-1 return code. The sketch I was trying to load was using pin 13 as a serial data output line. After reading this thread, I connected a few dots
and fixed the problem by adding the following code to the setup() function of my sketch:

pinMode(13,OUTPUT);
digitalWrite(13,LOW);

This code is the first to execute.

I also switched the rest of the program to stop using pin 13 at all.

This turns off the LED, and keeps it off. I haven't had an issue since.

Glad that this worked out, as my soldering skills are mediocre at best.

Thanks for posting your experience.
