Hi There
So i am trying to upload a sketch to the chinese arduino clone but i always get the avrdude error (see further down). The sketch is the Bilnk example.
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with programmer
An error occurred while uploading the sketch
I installed the chinese driver, i selected the right port, i tried all other ports, i tried to hit the resetbutton at the perfect time (Chinese Generic Mega 2560 Timeout Error fix! - YouTube), i tried to let go of the reset button at the right time and loads of other stuff like: different cables, different USSB ports, chanche the COM port.
I also tried the serial test, and it failed.
The test works like this. connect the RX0 to the TX0 pin. Open the serial monitor on the right port and just send a letter. afterwards the letter should be sent back by the arduino.
Now the strange part is.
i can upload a sketch from my laptop and never had a problem, the serial test also works on the laptop. Well i also didnt had to install the chinese driver for the serial communication chip (CH340G), i just plugged it in and it worked. The difference is, the laptop runs Win 10 but it also worked with Win 8 some moths ago. But it just wont work on my desktop computer, which runs Win 7.

Since it works on the laptop, i figured the boodloader should be ok, and i didnt reprogram the board.
if there are any questions, dont hesitate and i will try to answer them.
Thanks for the help.
