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 ::
http://www.instructables.com/id/How-To- … /?ALLSTEPS
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.
