Atmel ATF15xx Family: ISP Devices User Guide
Secure Verify Fail
This error occurs when the ISP software is unable to verify that a device is secured in
your JTAG chain. This can occur due to the following reasons:




No Devices Found
This error is generated when your JTAG hardware chain is incorrectly configured. Possi-
ble reasons for this error are discussed below:
1. Problem: The power to your circuit board was accidentally turned off.
2. Problem: Your circuit board does not contain an Atmel ISP device(s).
3. Problem: No cable is connected between the PC’s parallel port and the 10-pin
4. Problem: The Atmel-ISP cable is being used, but it is connected in the wrong
5. Problem: The Atmel-ISP software does not work when the cable is first con-
6. Problem: The Atmel-ISP software has been configured to use the Atmel-ISP
7. Problem: A device programmed on your circuit board has the JTAG port dis-
You have more than one device in your chain, and the other devices are not placed in
the Bypass mode.
The device you are trying to verify was already secured with a JEDEC file that either
disables the JTAG port or uses the JTAG port pins.
Solution: Make sure your circuit board is powered on before running the software.
Solution: Make sure at least one Atmel ISP device is inserted in your circuit board.
JTAG header on your circuit board.
Solution: Make sure you connect either the Atmel-ISP cable or ByteBlaster/MV
cable (if the correct software option is enabled) between the PC’s parallel port and
your circuit board.
orientation on the 10-pin JTAG header on the hardware board.
Solution: Make sure the red LED on the back of the Atmel-ISP cable is illuminated
when it is connected to the hardware board. If is it not illuminated, the cable is not
connected properly.
nected to the PC before being connected to the target board.
Solution: The Atmel-ISP cable contains active components that are powered from
the circuit board. Inputs to the active components are driven by the parallel port.
Connecting the cable to your PC first can cause the inputs of the active component
to be driven before the active components in the cable are powered up. This may
affect the operation of the ISP cable. Connect the 10-pin header of the ISP cable to
your target board first and power it up. Then connect the 25-pin DIN connector to
your PC.
cable but you are using the ByteBlaster/MV cable, and vice versa.
Solution: Change your ISP software configuration for the cable that you want to
use.
abled or is using the JTAG port pins as logic I/Os.
Solution: Remove the device from your circuit board, erase it on an external device
programmer and reinsert it onto your circuit board.
