I have a very strange problem. Using Arduino 1.6.5
In a fairly big sketch i included the ‘tone’ function. On one computer it works just fine. On another computer the upload fails with this error:
avrdude: verification error, first mismatch at byte 0x7000
0xff != 0x2f
avrdude: verification error; content mismatch
After compilation, the status is:
Sketch uses 29,414 bytes (91%) of program storage space. Maximum is 32,256 bytes.
Global variables use 1,047 bytes (51%) of dynamic memory, leaving 1,001 bytes for local variables. Maximum is 2,048 bytes.
Just by removing the statement:
from simple-co2-monitor-fw.ino / line 98 - then the sketch uploads successfully.
I’ve attached the sketch for reference.
Next thing i am going to do is to analyze in detail the two installations of the Arduino ide. But if someone faced this issue already I would be very thankful for some hints
