The only reason I installed a boot loader at all was to set the UPDI pin to GPIO...
The new megaTinyCore 2.1.4 allows setting the UPDI pin to GPIO without Optiboot.
Of course, make sure you have a working HV-UPDI programmer available.

Example of how your board settings would look...

With Optiboot



Non-Optiboot

Here, don't get confused by the wording "burn bootloader" or "Bootload burn req'd".
This just means that if any changes are made, you need to run "Burn Bootloader" in the Tools menu.
This won't add Optiboot ... it just updates the fuses.

I worked that out. I was just querying if optiboot did anything more in my case. Everything is now working great on Spence's board. Just waiting for my new boards to arrive from China.
Engineers design things.....technicians make them work.

I don't need anti-static wrist straps.....an instructor years ago told me I had no potential.

Let you write to flash in runtime? ATtiny3217 has 32KB flash.....

Your sketch can sense ongoing process events in time.
Your sketch can make events to control it over time.

I know. And I am using nearly all of it.
