ISP
programming
does not work ISP cable is not
connected Connect a 6-pin cable between the
ISP6PIN connector on STK500 and
the ISP connector on STK505 on the
selected target section. See also
Programming the AVR.
ISP
programming
does not work The AVR is running at
too low clock
frequency. Make sure the clock switch on
STK500 is in the right position. In
the Board page of the programming
dialog in AVR Studio, try reducing
the clock frequency so less or equal
to the frequency the AVR is running
at.
ISP
programming
does not work The SPI enable fuse is

not connected
correctly. See the Programming the AVR
chapter for setup.
High-Voltage

does not work. The (BSEL2),
OSCSEL, RESET and
VTARGET jumpers on
STK500 are not set
correctly. See the Programming the AVR
chapter for setup.

switch is in the wrong
position. Set the switch to the EXT CLK
position. See also Programming the
