Troubleshooting
Invalid Chain File
You have attempted to load a chain file, which the ISP software does not recognize. Use
the File.. New command to create a new chain file with the ISP operations you want to
perform and re-save it under your old file name.
Invalid Device ID
The Atmel-ISP software reads an incorrect manufacturer silicon device ID for an Atmel
ISP device on your circuit board. If any Atmel device has an invalid ID, you can still per-
form ISP operations on it by using the hidden ID Check Override command. However, it
is not recommended to override the device ID check feature.
For example, if you created a 2-device chain with ATF1508AS and ATF1504AS devices
but you actually have two ATF1508AS devices on your board, this error will be gener-
ated. It is not recommended that you override the IDCODE Check in this case.
The same error would occur if you have two ATF1508ASV devices in your chain file but
there are actually two ATF1508AS devices on your board. The workaround is to edit the
chain file accordingly to match the device types on your board.
Contact Atmel PLD Applications if you encounter this error with any Atmel ISP device(s).
Device number not valid
This error normally occurs when you are using the Edit, Add or Delete Device com-
mands and specify the wrong device number. The ISP software can flag the wrong
number if you specify a number greater than the actual number of devices already spec-
ified in your chain file. If you have a blank chain file, you cannot specify any device
number as no device information exists yet. In this case, edit the existing chain file to
add at least one device.
JEDEC file <Filename> disables the JTAG port on Chip <number>
The JEDEC <filename> you have specified will program the appropriate chip <number>
with logic that either disables the JTAG port or uses the JTAG port pins as logic I/Os.
The Atmel-ISP software generates this error because you cannot reprogram this chip
<number> or any other device in your JTAG hardware chain using the ISP software.
If this device is programmed, the only way to reprogram using ISP is to remove it from
you circuit board, erase it using an external device programmer and reinsert it in your
circuit board. If you still must program this chip, there is a JTAG port override option
available on the Atmel-ISP software.
JEDEC file not specified
You have specified an ISP operation that requires a JEDEC file to be specified. If you
are trying to execute a Program, Verify, Program/Verify or Program/Verify/Secure oper-
ation on any device in your chain file without a JEDEC file, you will see this error
message. Edit your chain file using the Edit Device command and specify a JEDEC file.
Both 5V and 3V devices in Chain File
This error occurs when you create a chain file that has both ASV (low voltage) and AS
devices (standard power).
This is currently not allowed by the Atmel-ISP software. You must create a chain that is
either all 5V or 3V devices. Creating a mixed-voltage device chain file may create func-
tional problems on your board if you have 3V devices that must handle 5V inputs. Also
