Hello,

I have a Iduino Yun Shield with a genuine arduino mega 2560 and i have a problem to upload the sketch.
When i change the sketch the code is not upload, why?

Thanks in advance

Code: Select all

Sketch uses 5,838 bytes (20%) of program storage space. Maximum is 28,672 bytes.
Global variables use 245 bytes (9%) of dynamic memory, leaving 2,315 bytes for local variables. Maximum is 2,560 bytes.

avrdude: AVR device initialized and ready to accept instructions
avrdude: Device signature = 0x1e9801
avrdude: Expected signature for ATmega32U4 is 1E 95 87
         Double check chip, or use -F to override this check.

avrdude done.  Thank you.

Hi,
I guess you have the wrong board selected.
The above result shows that the Yun Shield tries to program the Arduino with mega32u4 mcu but actually the Arduino is based on the mega2560 which has signature 0x1e9801, so it fails.To solve this issue, you can choose the board type to the correct one in the Yun Shield Web Interface --> Sensor --> Arduino Board type.
Even with that shield on it, the board you are using is still an Arduino Uno, not a Yun.
Regards

Look the image, I just select the arduino yun and the port of comunication wifi -> 192.168.0.2 that i access fine from my webrowser, OK



What i need to change?

Thanks a lot for your replay

Hi,my friend
I'm thinking shouldn't it be your MEGA2560 ?
