Suddenly lost Uno/Tiny88 uploading

[ptillisch]

Great news! I'm glad it is working now.

@Terrypin

not sure why it's there

I provided some information about it in one of your previous topics:

@Terrypin

I'm confused by the introduction of 'Micronuceus' to my thinking. Why when/should I need that?

@ptillisch

If you are using a board that makes a direct connection between the primary microcontroller and the USB cable, and thus uses V-USB for USB communication with the computer.

The most common such board is the "Digispark":

Another common board is the "MH-Tiny".

@Terrypin

Is it quite separate from the 'ATTinyCore'?

No.

@Terrypin

For context, I'm working with cheap ATTiny85 chips

If you don't have it connected directly to the USB cable, then don't use the ATTinyCore "Micronucleus" option. Just ignore the platform's Micronucleus support and everything will be fine.
