Troubleshooting
Atmel ATF15xx Family: ISP Devices User Guide
7-7
The reverse is true for devices that have an ID code (such as Atmel ISP devices). The
IDCODE box must be checked for them.
If the IDCODE box is in the wrong state, it will affect the bitstream that the software actu-
ally sees from your JTAG hardware chain versus the bitstream it expects to see. The
result can be either incorrect programming and/or incorrectly detecting the actual num-
ber of JTAG devices on your board.
If you attempt to uncheck the IDCODE box for an Atmel device in your chain, you will
receive this warning message with Atmel-ISP software, version 2.77 and higher. The
state of the IDCODE box, if it is unchecked, will also be indicated in your chain file.
IDCODE Checking is now <ON/OFF>
This warning occurs if you attempt to override the manufacturer ID check on the device
using the [Shift]-[Alt]-[L] key sequence. Selecting OK confirms the state of whether
IDCODE checking is either on or off. The Atmel-ISP software defaults to having the
IDCODE checking turned on. It will remain on until the hidden key sequence above
turns it off. It will remain off until turned on again by reentering the same key sequence.
JTAG Port Checking is now <ON/OFF>
This warning occurs if you attempt to override the “JTAG Port Pin” error by using the
[Shift]-[Alt]-[J] key sequence. This error occurs when your design is using the JTAG port
pins for logic. Selecting OK confirms the state of whether the JTAG port checking is on
or off. The Atmel-ISP software defaults to having the JTAG port checking turned on. It
will remain on until the hidden key sequence above turns it off. It will remain off until
turned on again by reentering the same sequence. The setting will remain in effect as
long as the Atmel-ISP software is running.
Mixed Voltage Device Checking is now <ON/OFF>
This warning occurs if you attempt to override the “Mixed Voltage Device Check” error
using the [Shift]-[Alt]-[V] key sequence. This warning appears when you are attempting
to program both 3V and 5V Atmel devices in the same JTAG chain.
Selecting OK confirms the state of the mixed-voltage device checking to be either on or
off. The Atmel-ISP software defaults to having the mixed-voltage device checking turned
on. It will remain on until the hidden key sequence described above turns it off. It will
remain off until turned on again by reentering the same key sequence. The setting will
remain in effect as long as the Atmel-ISP software is running.
Security Fuse Verify only Works for 1 Device
This warning message is displayed when you try to verify the security bit for more than
one device. The security bit can only be verified for one device at a time. All other
devices in your hardware chain must be placed in the Bypass mode. If you select Yes to
the Verify Secure command, then one device will be secured. If you select No, the Verify
Secure command will be cancelled.
Note:
It is recommended that you select No. Otherwise, you will not be able to deter-
mine which device is actually secured.
