Hi all.
After a long time of happily using the Arduino Mega I too got struck with the dreaded avrdude timeout error.
The problem just occurred without anything happening before it. There is something strange about this error. If I try to upload something I got the error, but if I reflash the bootloader I can upload for ONE time only. After that I got the timeout error again. I don't know if reflashing the bootloader erases the entire flash but the last sketch I uploaded will start again after reflashing.
My Arduino is from here and the ISP I use if from here here.
The code is not really relevant here but I will include it anyway.
void setup() {
pinMode(13, OUTPUT);
}
void loop() {
digitalWrite(13, HIGH);
delay(100);
digitalWrite(13, LOW);
delay(100);
}
After uploading that I try to reflash it with anything but it doesn't upload a second time. Serial output works like a charm and so are more complicated sketches but I can't reupload without pressing the reset button. This has some serious problems for me since I upload via bluetooth that also works a single time.
The error I got is
Sketch uses 1460 bytes (0%) of program storage space. Maximum is 253952 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 8183 bytes for local variables. Maximum is 8192 bytes.

avrdude done. Thank you.
An error occurred while uploading the sketch
My OS is Windows 10 pro and the arduino version I tried it with are 1.6.13 and 1.8.1.
I hope there is a solution for this.
