I bought this Chinese Arduino Mega 2560 16AU.
This was the first time to deal with Arduino boards. When I try to upload a sketch I always get this error:
stk500v2_getsync(): timeout communicating with programmer
I successfully burnt a bootloader to it using an Arduino uno,
but the same error is there.
Finally I discovered the the loop test is not working, and only the LX LED flashes once when I enter a letter in the serial monitor.
