I'm using tinyavr programmer ( TinyAvr ) for a while but today when i try to upload my code to attiny45 with avrdude i got these messages as you can see at the pictures. I know i can still upload my codes but code timing between chips is really important to me. Is any of you encounter such a problem like this or know how to fix it?
My guess is a problem with libusb, I was not able to get avrdude to work with my libusb based ISP tools when I had Atmel Studio installed, and I suspect other USB drivers can cause problems as well. I don't have these problems on Linux, all the ISP tools I have worked fine there. I guess it is just that I can not put Atmel Studio on Linux.
I use the ArduinoISP sketch (that is in examples) for most things now. I load it into an Uno and then use that as the ISP tool. It works when both Atmel Studio and Arduino IDE are installed. At this time I am doing most of my work with the AVR toolchain from Linux, and the Uno with the ArduinoISP sketch is still my goto ISP tool.
