• Avrdude Stk500_getsync() Not In Sync Resp=0x00 Arduino Nano

Hello forum people, I am having trouble getting the Arduino IDE to upload to the Arbotix board. I am getting the following error: Arduino: 1.8.9 (Mac OS X), Board: 'Arbotix-M' avrdude: Version 6.3-20171130. Binary sketch size: 1026 bytes (of a 30720 byte maximum) avrdude: stk500getsync: not in sync: resp=0x00 When I do the verbose upload (Shift+Upload), I get this error/message: avrdude: usbdevopen: did not find any USB device 'usb' Also, I tried adding 1k pull-up resistors at pins 2 and 3 of ATmega, but didn't help.

The ArduinoISP sketch should work just fine.Obviously your target AVR must have a valid clock signal.In my opinion, you never remove the AVR from an Arduino. If you want to use a different bootloader, you install it via the Arduino IDE. This ensures that the fuses and lockbits get set correctly.I can see little point in ever putting a bootloader onto a breadboarded AVR. It is simpler to just use ISP.You should never remove the RESET-EN solder-bridge unless you want to use debugWIRE. (or you never use the bootloader)Everyone has their own opinions.

It is not compulsory to make things difficult!David.

That might just be the wrong pin though.Also I removed the bootloaded stuff which might have helped (but a rate of 57600 still fails).EDIT: It works! Thanks David!For anyone else with the same problem: You need to clear out your bootloader (if you installed one) by removing the -D flag, and then run the upload commands manually with an overriding baud rate of 19200. What is the problem?You either run 2 regular ArduinosOr one ArduinoISP and the other as a regular ISPed board.No money involved, and no grief!Personally, I have several Arduino boards.I always keep the bootloaders, and use them with:CodeVisionRowleyAtmel StudioBascomAssembler.The program 'upload' involves either a mouseclick or is done automatically as part of the build process.It is far easier to test an idea or prototype a project with a 'standard' Arduino board than to lash up a breadboard.Your 'free samples' are better off living in a drawer.

When you have debugged your project with the Arduino, just re-compile for the wierdo sample and solder it into the finished project.YMMVDavid.
