Could be any number of things, but looks like maybe a signal integrity issue
or incorrect bitfile to me.
1. What length and kind of cable connects the 7I43 to the PC? (cable should
be IEEE-1284 compatible or flatcable, other printer cables may not have enough
grounds)
2. You are using a bitfile for a 200K 7I43, is the 7I43 a 7I43-2?. The 200K
7I43s are a bit rare.
2A. If you do indeed have a 7I43-2, I will check the SV8S bitfile here. I dont
think the 200k bitfiles have been tested as thoroughly as the 400K ones
3. The FPGA's EPP interface is more tolerant of bad end-of-cable signal
integrity than the CPLDs EPP interface (due to CPLD space limitations)
The FPGA bitfiles are CRC checked, but we have seen download problems that
the CRC checking misses.
One thing you might try to do to narrow down the problem is to load the
FPGA via the local EEPROM instead of from the host. This will require using
a windows machine and USB
