CPLD programmable logic / Programming CPLD with Bus Pirate?
Hi all :

I finally got my bus pirate v3b ( Jan2010 ) and XC9572 XL
( It took ~13 days to arrive )

My goal is to learn CPLD, therefore BPv3b is going to be used primarily ( as of now ) as programmer for the XC9672 board ( FPGA and CPLD programming) .

I performed hardware self test via terminal : passed.

Bus Pirate v3b
Firmware v5.10 (r559)  Bootloader v4.4
DEVID:0x0447 REVID:0x3043 (24FJ64GA002 B5)

As a stand-alone XSVF player to program CPLD/FPGA, this requires a simple firmware Swap.
Question :
1 "Load alternate firmware using your normal firmware update procedure" , does this mean the original bootloader ( in BPv3b)  would be erased from BPv3 ?

2 Does "Use your favorite firmware update program to load the BPv3SXVFplayer.vx.hex" mean I have to update via programmer like 'Pickit3' ? If so, could you list or mention some programs that are commonly used for this purpose ? I am not quite clear on how to achieve this.
Specifically, how do I load the alternate firmware ( what software with what cable ) ?

Perhaps, some block program or some form of graphic representation might help newbies like me to understand the procedures and/or mechanics to accomplish what you describe in your website better.

I have been playing with AVR mega & xmega and not familiar with this CPLD at all.
My apology if these questions are so trivial.

CPLD programmable logic / Help : newbie wants to learn CPLD
I am a newbie in CPLD area, currently auditing digital logic class at the local community college( reading : professional student == senior citizen) .

I plan to use your XC9572XL board since it can tolerate 5 volts.
I would like to use this board in conjunction with my arduino board.

I hope the learning curve is not too steep.

Quesion :
What kind of programmer hardware ( connecting cable) do I need ?
BusPirate ?

Please advice as to which programmer I should use.

thanks.
samira
