*Obsolete* 4.2i iMPACT - The software is incorrectly driving the /INIT pin of PC4 (Parallel Cable IV) Low ("Configuration Failed")

描述

Keywords: Parallel Cable 4, iMPACT, INIT, Low, configuration

Urgency: Standard

General Description:
In the 4.2i release of iMPACT, the /INIT pin of the Parallel Cable IV (PC IV) during FPGA configuration via slave serial is continually driven Low. This prevents the FPGA configuration from starting or functioning successfully.

解决方案

This problem is fixed in the latest 4.2i Service Pack, available at:
http://www.xilinx.com/support/techsup/sw_updates
The first service pack containing the fix is 4.2i Service Pack 2.

Alternatively, you may safely disconnect the INIT pin entirely when performing slave serial downloads.
