Olimex AVR-ISP-MK2 with BASCOM-AVR IDE

[LubOlimex]

Driver looks alright. What about he hardware connection between AVR-ISP-MK2 and the target? Which connector do you use for the connection? Target is ATtiny25 - what is the programming interface of that chip?

Did you also test with Atmel Studio just to confirm if the issue is specifically with Bascom?

The hardware is okay. But i messed with loading the hex files.
So i restarted all over again.
Fist loaded from Olimex AVR-ISP-MK2-firmware-windows drivers.zip and then extracted everything ( which i didn't not well ).
Then following the procedure from the manual: 4.2.1 changing firmware for windows users.
On point 5. file >hex files > AVRDUDE / arduino / libusb >
libusb-AVRISP-MKII.hex

At the end, everything was working fine.!!!

Thanks for always patiently replying.
