Hi, i have mega2560 made by myself (copy arduino mega 2560 r3). When i upload code:

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

rx led blinking, tx not.

I check TX and RX .. correct lines.
I load hex file to 16u2 via avrdude and flip.
And this is my dtr/reset line:

pin 13 is in 16u2 and reset in mega2560


Please Help :(
