I am working with atmega32 and facing a problem of portc pins are not working.0,1 and 6,7 bit are working but 1234 are not.
So how can it work?
 

Hi,

"Are not working" what does that mean?

As input or as output?
High, or low,

Show us your code, tell us what you expect and tell us what exactely happens instead.
Show us your schematic. Measure voltage levels...

Disable the jtag fuse on the M32.

Jtag uses pins on PortC

This may require setting proper fuse bits.
