Arduino Breadboard with Optiboot

[ujjwalbsoni20032003]

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.

Is there a specific setting to be done in Arduino IDE to enable Optiboot ?

You should have your "board" set to "Uno"
And if you're using manual reset, you only have a one-second window for the "correct" time to release the reset button. I usually set "verbose" mode and let the reset occur just after the compile completes.

This is kinda wide open, what do you know that does work? For example, did you first get this working on a solder-less breadboard, have you tested the max232 board, have you checked your 5v supply, can you pre-load a blinky (or better yet a serial output) sketch in the 328 and see if it even just runs, and if it does, doe pushing the reset button then actually reset the chip?. Also, do you know about holding the shift key in the IDE while programming to get verbose output?
