Help
I can't burn a bootloader for attiny85 boards. I am trying to use them in a serial rs485 project and the bootloader cannot be burned.
I have tried all day and used veraious methods with the USBASP v2 and using an Arduino Zero clone and cannot get attiny85 to work with serial or accept a bootloader.
Specifically I can flash micronucleus 16.5mhz onto it and make sketches with the digispark board selected but I cant update a bootloader for 8mhz or 16mhz and it is always 16.5 or the mystery factory bootloader.
I also tried the adafruit trinket but to no avail.
my setup is window$ with usb 1.1 port being used (not even 2.0 but I have 3.0 and dont use them)
I am using a USBASP which can burn micronucleus using the avrdudeGUI
but I cannot find or get the other firmware files in arduino ide to try to burn them.
I keep getting this error:

Error while burning bootloader.
I also noticed that the libraries available are now "per board" and this completely breaks a lot of things and requires way too much copy and paste. Is there anything that can make this easier or should I be using an older adruino ide?
