Hi, Win 10 version 20H2, IDE version 1.8.12
attempting to install Sparkfun ATtiny85 board
In my sketch/hardware folder I have placed the attiny folder which contains the AVR folder, which contains the boards.txt file. I reboot the IDE and load a simple sketch to blink the onboard led. When I try to verify or load the file I get the subject error message. When I try to select the board the entries contained in the boards.txt file are not there. It appears that the file is not being read.
Any thoughts would be appreciated. Thanks Ernie
