The Green “VCC-ON”
LED is not on
DVK90CAN1 does not
work
The AT90CAN128 cannot
be prgrammed
AVR Studio does not
detect the AVR tool used
Problem
No power supply
The
STK500ISPheader
is not connected.
The AVR ISP probe is
not connected
The AVR JTAG ICE
probe is not
connected
The memory lock bits
are programmed
The fuse bits are
wrong programmed
Programming too fast
with ISP SPI
Serial cable is not
connected, or power
is off
PC COM port is in
use
AVR Studio does not
detect COM port.
Troubleshooting Guide
Reason
Switch-on the “POWER” switch
Verify the power supply source
Connect the DC power supply source
Connect a 6-pin flexible cable from
STK500 ISP6-PIN header to the correct
DVK90CAN1 ISP header (page 35)
Connect the AVRISP6-PIN header to
the correct DVK90CAN1 ISP header
(page 34)
Connect the JTAGICE 10-PIN header
to the correct DVK90CAN1 JTAG header
(page 35)
Erase the memory before programming
Check the fuse bits
Check oscillator settings and make sure
it is not set higher than SPI clock
Connect serial cable to RS232 (STK500 -
AVR ISP - JATG ICE ) and check power
connections
Connect serial cable to USB (JATG ICE
MKII) and check power connections
Disable other programs that are using
PC COM port.
Change PC COM port
Disable COM port auto-detection in AVR
Studio file menu. Force COM port to
correct COM port
