5 years ago This core only supports the included optiboot serial bootloader; there is an open issue (with no planned version) for adding support for the micronucleus/digispark bootloader, but there is not presently support for that, and it is considered a low development priority (i have a low opinion of vusb bootloaders - they are space hogs, and have compatibility issues with some usb hosts, because they arent quite compliant with the usb standard, and require external components that nobody tells you about the ramifications of, ex. on digispark boards that integrate the parts on that "programmer" and chip onto one board, with no way to remove the chip). I often just use isp programmers and no bootloader to maximize available flash.
Also, despite what that vendor calls it, that is not a programmer - thats just the external components needed for vusb and a usb socket; you need a chip with a vusb bootloader on it already. A programmer would have another chip on itt that could program the target chip (for avrs, via ISP - for example a usbasp or usbtinyisp - both are dirt cheap and work great), and could be used to put the bootloader on a virgin chip and set the fuses.

I everyone, i recently bought a usb programmer https://goo.gl/ixTHbH . I checked the connection, https://goo.gl/49LWK2 , and i immediately realized that this usb programmer uses the PB4 and PB3 to program the board ( micronucleus bootloader ).
I read the references for the ATTinyCore bootloader for the tiny85, it uses the pins PB0 and PB1.
Can i burn the micronucleus bootloader and flash the code without the ATTinyCore bootloader? Or it doesn't works?
