Bus Blaster v4 power up test success, bitstream next

January 20, 2012, 02:13:46 pm

There are a number of Bus Blaster v4 free PCBs out there. Anyone build one? I finished the v4 and did the power up test, it enumerated ok. Next to adapt the bitstream and try the self-test.

I'm looking for the CPLD to finish mine.
The wiki partlist says XC2C64A but doesn't seem to be the correct part number.
It will be a nice mate to my recently finished Cygni board.

Exact part number is: XC2C64A-7VQG100C

Thanks Ian,
Neither farnell, mouser or rs components carry them.
Do you have any recommendation where to get them in Europe?

I'm sorry, I don't I got them from digikey. If I had not used both of them makeing prototypes I would send you one.

No worries,
I will wait until I have more digikey only available products and will do a batch order (have a couple more already).

Hello everyone. New to the form. First post :)
I'd love to put one of these V4s together and try to get it working. Do you have any PCBs left? If so, let me know how I can get a hold of one. If not, when do you think you will get another batch? Find any artwork bugs that need a new cut?
Thanks.
NLC

I'm sorry NLC, this one was super popular and all the PCBs are gone. There is a chance of another batch, depending on if there are bugs in this version, otherwise it will go straight to production.

Can't wait for the next batch ..... :-)

Anyway, how are the tests coming ?

How's the debug progress going? I know you probably hate this question by now, but could you take a rough guess as to when you think more boards or a finished unit would be available? Weeks, months, years?

Probably years, this is just a fun project, we have no intent to produce it at all at this time.

Hi, I received your board and I want to buy components but I don't known reference of FTDI chip if it's ft2232hl or ft4232hl

I don't find any value of inductors in ft2232's datasheet. What are values that you put ?
Can I use xc2c256-vq100 for cpld ?

Thanks

Bus Blaster v4 uses ft2232H.

Any ferrite bead will work, or just leave it off and solder a jumper. Here's our beads:

That CPLD is fine. More expensive and you will need to compile your own bitstreams.

Hello, I finnished to sold component on the board, but I can't programme cpld. I notice that 1.8V power pins of CPLD isn't powered by ftdi, the 1.8v track isn't routed with the pin regout of ftdi. Is it an error or not ?

You are totally right. The net is named +5V and is not connected. You will need to solder a jumper from C19 or C23 to C1, C2, C3, or C8.
