xc9572 project

Hello,

i use platform usb cable. and xc9572XL -10

i install and erase the PLD for 4-5 times, but now when i want to install the PLD:

the imPACT freezes, says
Device #1 selected
// *** BATCH CMD : Program -p 1 -e -v
PROGRESS_START - Starting Operation.
Validating chain...
Boundary-scan chain validated successfully.
'1': Erasing device...
Erasure completed successfully.
read count != nBytes, rc = 20000015.
read failed 20000015.
write cmdbuffer failed 20000015.
write cmdbuffer failed 20000015.
write cmdbuffer failed 20000015.
.
.
.
write cmdbuffer failed 20000015.
write cmdbuffer failed 20000015.
PROGRESS_END - End Operation.
Elapsed time = 256 sec.
write cmdbuffer failed 20000015.



and also erasing and readback is succesfully.

can be the PLD damaged? for 5 times erasing?

(i dont use pull up resistor for TDI TMS TCK)

Added after 4 hours 8 minutes:

anyone to help?

how many times can we install the PLD?
is it limited by the MacroCells we use and the macrocell exists in the PLD??

thank you,
regards.

Are you sure your download wire good?

Are you sure your Software system configure right?

You'd better call XILINX FAE:)

The XC9572XL has endurance exceeding 10,000 program/erase cycles. (Those words are from the datasheet.)

I've never seen your error message. Be suspicious of anything (hardware or software) that changed since the last time it worked.

Maybe some project setting got messed up somehow. I would try building a new simple project in a clean directory, then try programming again.
