but reports the wrong number of devices.
Solution: Check whether any device in your JTAG hardware chain was pro-
grammed with a JEDEC file that buffers the TDI pin to the TDO pin. Remove this
device from your circuit board and erase it using an external device programmer.
Atmel-ISP software should report this error.
Solution: Make sure to specify the correct device type in the chain file.
board.
Solution: Your JTAG hardware chain must be hardwired correctly on your circuit
board before you can implement ISP. See also “Setting Up Your Target System” in
Section 5, “Getting Started”, for the correct setup of your JTAG hardware chain.

Solution: Go to File..Port Setup to change to the correct LPT port setting.
ware still fails to communicate with your circuit board.
Solution: Change your parallel port setting in BIOS to either the ECP or EPP mode.
If you are using Windows 3.x or Windows 95/98, you can also configure Windows
to select the correct ECP or EPP port driver. For details, contact Atmel PLD
Applications.
earlier version works but the newer version does not.
Solution: Try to use the Self-Calibrate or Manual Calibration options. These options
can be used to slow down the transfer speed the software uses when communicat-
ing between your PC’s parallel port and the hardware. The Atmel-ISP software may
not be able to communicate reliably on some PCs at faster parallel port transfer
speeds. The Self-Calibrate and Manual Calibration options adjust the transfer speed
the software uses so it can reliably communicate between the PC’s parallel port and
your hardware. Older versions of the software communicate at a slower transfer rate
(approximately 50% slower) than newer versions.
fails to communicate with your hardware.
Solution: You need a different version of the ISP software (ATMISPNT) to be able
to run on Windows NT 3.x and above. The Windows NT version of the Atmel-ISP
software is also available on Atmel’s web site and BBS for download.
system to the appropriate VCC and GND pins, respectively, on the 10-pin JTAG
header(s) on your board.
Solution: Wire up the VCC and GND pins on the JTAG header to their respective
VCC and GND buses on your board.
Contact Atmel PLD Applications if none of the above suggestions appear to
resolve this error.
