*Obsolete* 4.1i iMPACT - 9500/xl/xv - iMPACT erases devices that have been read-protected


Keywords: iMPACT, 9500, read protect

Urgency: Standard

General Description:
When I attempt to program a 9500/XL/XV device that has been read-protected, the following error message appears, then the device is erased:

'1': Performing blank check on device ...
'1': Device is not blank.
'1': Blank check completed successfully.
Validating chain...
Boundary-scan chain validated successfully.
'1': Putting device in ISP mode...done.
'1': The device has 'read-protection' enabled. No read operations are allowed when in this mode.
To disable read protection you must erase the device.

(Attempting to program a read-protected device should not result in the device being erased.)


This problem is fixed in the latest 4.1i Service Pack, available at:
The first service pack containing the fix is 4.1i Service Pack 1.
