Topic: avrdude: stk500v2_ReceiveMessage(): timeout error message (Read 169 times) previous topic - next topic


Hello everyone!

I made my own version of the Arduino Mega and I just populated the board using components from a working Arduino Mega board. I soldered the 16u2 QFN chip using a soldering oven and hand-soldered the surrounding peripherals. I then connected it to my computer via USB and the com port was recognized correctly.

I then soldered the 2560 chip and its peripherals and tried to upload the blink sketch to verify everything was working. At this point, I get the error message mentioned in the title maybe five times and then the window shows the avrdude: stk500v2_getsync(): timeout communicating with programmer error message and that's it. Does anyone know why this could be? Below is a screenshot of my pcb, so let me know if there are any trace issues that can cause this.

Time line? Time isn't made out of lines. It is made out of circles. That is why clocks are round.
