Support Forum » Newest irritation No longer can program MCU

I tried to program a ATmega168 that I have not used in a while.

The compiler ran through everything and said Thank You.

So I believe it compiled but now I cannot set the MCU to run mode.

All I get are the two bars.

So I tried another MCU which had a working program loaded and it gets the same results:

Two black bars.

Then I tried using a different breadboard and loading the program.

Now the compiler hangs at:

miniMac:tempsensor Me$ make
avrdude -c avr109 -p m168 -F -b 115200 -P /dev/cu.PL2303-0000101D -U flash:w:tempsensor.hex:a

I get the same hung results with the original breadboard also.

Both MCUs hand when trying to load a program and show two black bars when trying to run.

Any idea about how to reset the MCUs?

Anyone have any idea about what I should do or look for?

When in programming mode it just hangs at:

miniMac:tempsensor Me$ make avrdude -c avr109 -p m168 -F -b 115200 -P /dev/cu.PL2303-0000101D -U flash:w:tempsensor.hex:a

Duh, I "forgot" to switch back to the 168 makefile in the libnerkits folder.

For the past month I have been programing a ATmega328p MCU and had tried to program a ATmega168 forgetting to switch back

to the 168 makefile. Gee imagine once I used the correct makefile it works.
