Problem Title:
LogiCORE PCI: Updating HOT II card from v1 to v2 after accidental erasure of the
Configuration Flash Memory
Problem Description:
Keywords; hot, II, vcc, upgrade, flash, configuration
Urgency: normal
General Description
While upgrading the VCC HOT- II card from v1 to v2, it has been found that it is
possible to erase the configuration flash memory during the upgrade process
when following the VCC notes, ie doing a hard rather than soft reboot after
updating the CPLD. Hunting at the device pins with an oscilloscope will show
that the CPLD and Spartan FPGA are okay, one trying to cause configuration,
the other waiting to receive the data. The flash output stuck high
(contains all Fs when empty).
Solution 1:
To get around this problem the following has been done successfully:-
1) Follow the software update instructions as per the VCC notes.
2) Follow the CPLD update instructions as per VCC notes.
3) Power down and wire up the VCC card connector 6 to the Xchecker cable.
The docs have the Xchecker INIT connection missing, this should
be connected on the same side as PROG two pins to the left (pin 6).
4) Remove jumper J6 from VCC card.
5) With the VCC card powered up invoke the Hardware debugger.
Select the bit file bflh_20.bit, from ...\HOT2\Hwif\BaseCfg\BootFlash\Spartan
directory and download via Xcheker. Done LED on VCC card ought to light up.
This shows that a good bitstream has gone into the Spartan witha PCI interface.
6) Perform a SOFT reset of your machine, the computer and VCC card
must remain powered. Start-->Shutdown--->Restart Computer, is
perhaps the safest method.
7) Invoke the VCC Test Commander program and follow the
VCC notes for updating the configuration flash memory.
Once this is okay you ought to be able to power down the
card and computer (HARD reset) then see it self configure
straight away with power applied. Done LED lit.
8) Replace jumper J6.
9) Carry on with your work.
