Arduino Breadboard with Optiboot

Hi,

I have developed Arduino Board using ATMEGA328-PU and bootloaded it with Optiboot using USB programmer. I connected my arduino board using MAX323 serial connection. When i connect my board to my PC and try uploading blink sketch. I get below error ::

avrdude: stk500_getsync(): not in sync: resp=0x00

I press reset button every time before uploading sketches but still get this error.

I followed instructables article mentioned in below URL ::

I tried all ways but its still in vain. Is there a specific setting to be done in Arduino IDE to enable Optiboot ? I have attached photos of my Arduino Board & Max232 board.

Please help.

Thanks,

What board type are you selecting for sketch downloads? Uno, or something else?

Have you posted similar elsewhere? Where perhaps I suggested copying the Uno section in boards.txt?

Hi,

Thanks for replying. I am selecting board type Arduino UNO and my serial port baud rate is set to 115200.

Thanks,
