A detailed description of the problem
Manual Firmware Upgrade
If an automatic firmware upgrade fails, or for some other reason connection to STK600 cannot be established, a manual firmware upgrade may
resolve the problem.
The AVR device can not be
programmed using JTAG.
low
The JTAG headers are not
connected
Connect the 10-pin flexible cable between the two 10-pin JTAG headers. See
JTAG Programming
.
The JTAG enable fuse is un-
programmed
Program the JTAGEN fuse using
Parallel High Voltage Programming
or
Serial
High Voltage Programming
The memory lock bits are
programmed
Erase the memory before programming
The AVR device can not be
programmed using high-
voltage programming.
The VTARGET voltage is too
low
Ensure that the voltage is at least 4.5V.
The high-voltage programming
headers are not connected
Mount cables between the programming headers. See
Parallel High Voltage
Programming
or
Serial High Voltage Programming
The reset jumper is not mounted Mount the reset jumper
The I/O ports are connected to
peripheral circuitry (leds,
switches, etc.)
Remove all peripheral connections from the I/O ports belonging to the high-
voltage programming interface.
The memory lock bits are
programmed
Erase the memory before programming
AREF0 jumper mounted
For some devices the AREF0 is connected to a pin used for the parallel
programming interface. The AREF0 jumper must therefore be removed to do
parallel programming of these devices. See the Parallel High Voltage
Programming section for which routingcards this applies.
AVR studio can not connect to
STK600
USB cable is not connected, or
power is off
Connect USB cable
Firmware is in an hang-up state Toggle power on STK600.
The status LED is blinking
orange
Wrong combination of routing
and socketcard, or card removed
when the kits is powered.
Check the device support file for routing and socketcard combination. Allways
turn of kit power before removing or mounting routing and socketcards.
The status LED is blinking red
There is a short circuit on
VTarget or AREF
Resolve the short circuit.
The status LED is blinking red To much current drawn from
supply
If the kit is powered from USB, try connecting a external power to the DC jack.
The LEDs don't work (running
from external VTarget.)
STK600 must be powered for
LEDs to work.
Supply power to STK600 and turn it on.
