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

Hi,

I am using ATMEGA328P-PU bootloaded with Arduino UNO optiboot. When i press reset button, LED connected on PIN 13 blinks.

When i upload using Arduino IDE and upload blink sketch, LED blinks 3 times but i get below error

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

I have selected Arduino UNO board and serial port is correctly configured.

below is the verbose output i get :: Please help

I am using ATMEGA328P-PU bootloaded with Arduino UNO optiboot.

The target processor is ... on a breadboard? in your Uno?

3

How can i find that ? Chip is ATMEGA328P-PU with optiboot UNO.

Below are the contents for boards.txt file for UNO

uno.name=Arduino Uno
uno.upload.protocol=arduino
uno.upload.maximum_size=32256
uno.upload.speed=115200
uno.bootloader.low_fuses=0xff
uno.bootloader.high_fuses=0xde
uno.bootloader.extended_fuses=0x05
uno.bootloader.path=optiboot
uno.bootloader.file=optiboot_atmega328.hex
uno.bootloader.unlock_bits=0x3F
uno.bootloader.lock_bits=0x0F
uno.build.mcu=atmega328p
uno.build.f_cpu=16000000L
uno.build.core=arduino
uno.build.variant=standard

I'm asking where your ATMEGA328P-PU is physically located. Is it plugged into a breadboard? Or is it plugged into your Uno?

5

Its located on breadboard. I have made an arduino uno board on breadboard

6

Did you include the auto-reset circuit?

7

yes i have included Auto-Reset Circuit, when i upload a sketch, reset led blinks 3 times.

8

What are you using for a USB-to-serial converter?

Does your breadboard Uno pass a loop-back test?
http://arduino.cc/forum/index.php/topic,73748.0.html

9

Yes, it passes loopback test. I am using a serial connection using MAX232.

10

Are you certain you have TX and RX wired the correct way around?

What value crystal or resonator are you using?

11

Yes, RX TX connectors are wired correctly. I am using 16k crystal value.

I have attached pictures of my breadboard.

When i upload using Arduino IDE and upload blink sketch, LED blinks 3 times but i get below error

How fast are the blinks?

13

1 second for each blink..total 3

14

Then you either do not have Optiboot installed (you have a different bootloader installed) or you do not have the fuses set correctly on the target. The first option is much more likely to be correct.

Optiboot blinks the LED extremely fast. It is actually difficult to tell that there are three blinks.

15

Hi,

I again bootloaded a fresh new chip with optiboot loader but still face this issue.

How can i set fuses on target ? Is there any setting for this ?

16

Hi,

Is there a different fuse setting for ATMEGA328P-PU ?

I use below

uno.bootloader.low_fuses=0xff
uno.bootloader.high_fuses=0xde
uno.bootloader.extended_fuses=0x05
uno.bootloader.unlock_bits=0x3F
uno.bootloader.lock_bits=0x0F

Is this correct ?

Thanks,

Are you using the Arduino IDE to install the bootloader?

18

ujjwalbsoni20032003:
Is this correct ?

Yes.
