Can't program ATtiny85 with ATTinyCore v1.5.2

Hi again,

with the beta4 I can't program an ATtiny85 anymore, the selected programmer Arduino as ISP isn't accepted:
Upload error: Error: 2 UNKNOWN: a programmer is required to upload for this board
A Mega2560 works fine.

In Arduino 1.8.13 I have no problems programming the Tiny, so the ATtinyCore v1.5.2 seems to work properly.

Here is the list of my additional board managers:


Hi @lorandil. The related bug report is here:

The classic Arduino IDE has a feature where the boards platform author can configure the "Upload" button to work like Sketch > Upload Using Programmer. This is convenient for boards that don't have a bootloader, where you always want to do an "Upload Using Programmer". DrAzzy has configured the ATTinyCore boards that don't use a bootloader in this way.

Unfortunately, Arduino IDE 2.x doesn't currently support this feature. Fortunately, there is a very easy workaround: just use Sketch > Upload Using Programmer (Or Ctrl + Shift + u if you prefer) when uploading to your ATtiny85.

Ok, that works!
Thanks alot :slight_smile:

You're welcome. I'm glad to hear it's working now. Enjoy!
