Getting Error : "A programmer is required to upload" while using megaTinyCore for ATTINY204

[Sourabh0912]

Hi Spence,
I tried compiling your megaTinyCore for my ATTINY204 IC, but while compiling and uploading code i am getting error " A programmer is required to upload"

I also want to read and print ADC data on serial port. Can you please help me.

What programer are you using? Changing fusebytes can only be done via external programmer, and if not using optiboot or if burning bootloader for first time a programmer is needed.

Can you please suggest steps, How to use ATTINY with megaTinyCore.

Where has this "a programmer is required for upload" come from? Are you using Arduino 2.0.x? I don't think that branch is of release quality yet; it has lots of novel bugs and regressions

If using 'Arduino 2.0.x', don't use the arrow 'Upload' button, you must explicitly choose Tools -> Upload using Programmer.

There us almost certainly some incantation I could add to fix this.... but I don't know what it is.

Marked as help wanted and mystery in the hopes that someone who knows how to make normal upgrades use the selected programmer on 2.0.x versions of the IDE will see it and let me in on the secret.
