A problem with my Arduino Serial Board

Hi everybody.
I have a problem to upload sketch's.

  • My operating system is Windows XP-SP3

  • I have a Arduino Single-Sided Serial Board with atmega168.

  • I worked with the board for a month and stop off for fifteen days, and then I installed PIC C, ORCAD and MPLAB. Now I can not upload any sketch.

  • The message displayed when I try to upload is:

avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

I thank anyone who can help me with my problem.

If you've updated your IDE recently, make sure you change the board back to the correct board under Tools.

Also, I'm not sure if the serial board you have, is using the auto-reset, so you could also try pushing Reset as you're trying to upload the sketch.

But chances are you just have the wrong board selected, also make sure it's the correct COM port. :smiley:

Hi everybody.

Again, I have the rigth board in Tools, my board have auto-reset, and use the only COM.

I reviewed the serial port, circuit and the atmega168 because it run the last skecth that I upload.

I donĀ“t know which is the problem.

I thank anyone who can help me with my problem.
