New PC: Setting processor to "ATmega328P (Old Bootloader)"

Development Tools IDE 1.x
1

Hi,

I've recently upgraded my PC and with it I've reinstalled the Arduino IDE.
When I originally set up the IDE on my old PC I had to

  • Download a special Serial driver
  • set the processor to "ATmega328P (Old Bootloader)" before I could program my Arduino nano.

I can do the first set, and the serial monitor is happily talking to one of my older projects. However, I can't for the life of me see how to set the processor. With out it I can't upload a new sketch. May be I'm using a later version of the IDE that requires me to download a board definition from somewhere?

For reference, the version I'm using is called 1.8.13 (Windows Store 1.8.42.0)

Some people have reported issues with the windows store version and we usually recommend removal and then going to the full IDE.

Also ensure you are NOT defaulting to Microsoft's ONEDRIVE as a storage location as that too can cause issues.

Use the search (upper RIGHT) to find these and more answers.

Hello.

Can take a few moments to Learn and Use The Forum

It will help you get the very best out of the forum in the future.

  • Your OS and version can be valuable information, please include it along with extra security you are using. Antivirus etc.

  • Always list the version of the IDE you are using and the board version if applicable.

  • Use quote or add error messages as an attachment NOT a picture.

  • How to insert an image into your post. ( Thanks @sterretje )

  • Add your sketch where applicable but please use CODE TAGS

  • Add a SCHEMATIC were needed even if it is hand drawn

  • Add working links to any specific hardware as needed (NOT links to similar items)

  • Remember that the people trying to help cannot see your problem so give as much information as you can

COMMON ISSUES

  • Ensure you have FULLY inserted the USB cables.

  • Check you have a COMMON GROUND where required. ( Thanks @Perry)

  • Where possible use USB 2.0 ports or a USB 2.0 POWERED HUB to rule out USB 3.0 issues.

  • Try other computers where possible.

  • Try other USB leads where possible.

  • You may not have the correct driver installed. CH340/341 or CP2102 or FT232 VCP Drivers - FTDI

  • There may be a problem with the board check or remove your wiring first.

  • Remove any items connected to pins 0 and 1.

COMPUTER RELATED

  • Close any other serial programs before opening the IDE.

  • Ensure you turn off any additional security / antivirus just to test.

  • There may be a problem with the PC try RESTARTING it.

  • You may be selecting the wrong COM port.

  • Avoid cloud/network based installations where possible OR ensure your Network/Cloud software is RUNNING.

  • Clear your browsers CACHE.

  • Close the IDE before using any other serial programs.

  • Preferably install IDE’s as ADMINISTRATOR or your OS equivalent

ARDUINO SPECIFIC BOARDS

  • CH340/341 based clones do not report useful information to the “get board info” button.

  • NANO (Old Types) some require you to use the OLD BOOTLOADER option.

  • NANO (ALL Types) See the specific sections lower in the forum.

  • NANO (NEW Types) Install your board CORE’s.

  • Unless using EXTERNAL PROGRAMMERS please leave the IDE selection at default “AVRISP mkII”.

  • Boards using a MICRO usb connector need a cable that is both DATA and CHARGE. Many are CHARGE ONLY.

CREATE editor install locations.

  • On macOs ~/Applications/ArduinoCreateAgent-1.1/ArduinoCreateAgent.app/Contents/MacOS/config.ini

  • On Linux ~/ArduinoCreateAgent-1.1/config.ini

  • On Windows C:\Users[your user]\AppData\Roaming\ArduinoCreateAgent-1.1

Performing the above actions may help resolve your problem without further help.

Language problem ?

Try a language closer to your native language:

Thanks to all those who helped and added to this list.

However, I can't for the life of me see how to set the processor.

  • Open the Tools > Board > Arduino AVR Boards menu.
  • From the menu, click on "Arduino Nano".
  • Open the Tools > Processor menu.
  • From the menu, click on "ATmega328P (Old Bootloader)".

@ballscrewbob, Thanks for the advice, I've reinstalled using the latest download on this site. I'm now running version 1.8.13

@pert, That might have been what I did when I installed it on my original PC.... Your instructions worked perfectly. :slight_smile:

I'm glad to hear it's working now. Enjoy!
