Hy,
I would like build a 2.1 hardware version OS, at first I wired in a beardboard just the Atmega644 (I attached that I bulit) and connected wia USB to my PC. the Win says: unknown device, I pushed an released the B2 button, as you offered, but i can’t install the correct USBasp driver
My Atmega644 is brand new, I newer upload any bootloaders.
It’s needed to upload an USBasp bootloader first via ISP, or what can I do for working?
