AR# 1560

*Obselete* FPGA Configuration 5000: Express Mode requires CRC disabled or INIT will go LOW.

Description

Keywords: 5000, express, mode, crc, init, makebits

Urgency: Standard

General Description:
XC5200 Express Mode does not support CRC checking. If CRC
checking is not disabled in MakeBits, INIT will go LOW,
causing interruption of configuration.

Solution

Hence, disable CRC checking with the '-f CRC:Disable' option in
MakeBits. This will ensure that INIT will stay HIGH throughout
configuration.
