Problem Title:
XPP, HW-112:  XPP v5.2.0 does not recognize 4020EHQ240 .bit file


Problem Description:
XPP 5.2.0 has problems reading 4020EHQ240 .bit files generated by
MAKEBITS 5.2.1a.  The typical symptom is that XPP flashes some message
very quickly across the screen, then prompts the user for a
file name.


Solution 1:

The XC4020EHQ-240 is only supported under XACT 5.2.1.

Workaround:

Use MAKEPROM to convert the BIT file to an MCS file. XPP will then accept
the MCS as a valid data file.

To generate the mcs file, run:

	makeprom -f mcs -u 0 p1284lca.bit
