USBtinyISP works for atmega328 but not atmega32

Post by superscrappy »

I have a USBtinyISP that I assembled from a kit. The programmer works great for an atmega328 but I am not able to initialize an atmega32 mcu. I get the following error when I try to check the fuse (or upload a hex file).
avrdude error with atmega32

The set up looks like the following:

Do I have a bad mcu? Again, it works just fine with an atmega328 but I can't initialize the atmega32. I've tried powering the mcu with the programmer and also from an external source, both result in the same error shown above.

Any help would be greatly appreciated!!

if it works with a 328 and not with something else, its a wiring problem of some sort on your protoboard, not the programmer
