avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x10

Hi all

Sorry if I repeat an old question, but I only find unanswered questions about this topic and the problem seems to be related to the upgrade I did from IDE 1.8.5. to 1.8.9 (on macOS Mojave).

Since a couple of years I succesfully flash my own barebone Arduinos, using ATMega328 ICs and a self-made programming shield.
When burning the bootloader or uploading any sketch with Arduino as ISP I recently started getting this error message. I only recently started using IDE 1.8.9. After returning to 1.8.5, my previous version, I do not get the error, except for the first waring line that does not seem to have any effect.

The last line, in Dutch, says "the selected serial port does not exist or your board is not connected".

avrdude done.  Thank you.

Should anyone have a solution or a better place to ask, please let me know.

Try connecting a 10 uF capacitor between the reset and ground pins on the board you're using as an Arduino as ISP.

Arduino recently changed the protocol used by the Arduino as ISP programmer from stk500v1 to arduino in order to allow ATmega32U4 boards like the Leonardo to be used with Arduino as ISP. An unfortunate side effect of this change is that it makes it more likely that the reset disabling capacitor will be needed on boards where it was previously not necessary. This change has been reverted and a new "Arduino as ISP (ATmega32U4)" programmer added for compatibility with Leonardo, etc., but there has not been a new release since that time:

Thank you, pert!
I'll give it a try en post my findings asap.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

please help

@sivimj please don't hijack threads. We'll use your dedicated thread to help you with this problem:

Try connecting a 10 uF capacitor between the reset and ground pins on the board you're using as an Arduino as ISP.

Can we solder this cap for permanence? I hope it does not hamper the working of the Arduino Board.

The purpose of the cap is to disable the auto reset circuit on the Arduino board. The reason for that circuit is because the microcontroller on the board must be reset at just the right time during the upload process to activate the bootloader. If you disable the auto reset circuit, you will need to manually reset the board whenever you upload.

The capacitor solution is used specifically because it’s not permanent. If you want something more permanent, you can cut the “RESET-EN” solder jumper that you will find on most Arduino boards with an auto reset circuit.

You will have to remove the capacitor from programmer board when uploading sketch on it. And when you use it as arduino as isp, you will again have to add cap between reset and ground.
