Superpass2 in a Superpass1 case?? And no programmer!

The_Legend · June 14, 2006, 08:21:31 PM

When I received my supercard + superpass (I've ordered a passme, but for some reason I received a superpass), I thought it was a superpass1, because there's no "2" on its label, but when I openned it today (got an ugly cut on my finger, btw. damn glued stuff!), it looks like it's a superpass2, due to the fact that it has a switch and the bottom back connector (used to make a jtag cable) are missing! Here a picture of the case and the back of my superpass"1 or 2":

As you can see, the label make it looks like a superpass1, but the inside makes it a superpass2. But I haven't received the programmer for the superpass2! here's the casing I received my supercard from:

And now I don't know what to do to make my superpass"whatever" work with my upcoming DSL... my first thought is to make a superpass2 programmer myself, but I can find the necessary information to do so! Can anyone help me??[/img]

Well, a superpass2 does come pre-configured as a "passme1". You will need a programmer to get it to work with an NDSL. I could program it for you if you want.

Thanks a lot, but do you live in Brazil? I don't think so, and with the customs people on strike now, it would take A LOT of time for it to go to your place and back to mine xD.

What I really what is a scheme of how to make a superpass2 programmer. I mean, the superpass2 connection versus the DB25 connector...

Oh, Brazil.

All pass through devices are basically the same design as passme1. See if you can identify the pins.

I've seen that picture already, and I can understand the DB25 part, but not the passme / superpass one... here's the thing:

Here's the connection using the original passme:

and that's the back of a superpass1:

but my superpass"whatever" misses that bottom pads, so I have no clue of where I should sold each part of the connector. Oh man, I wish my superpass was the superpass1

See the CPLD (chip) in your picture of passme1. See if you can follow the pad traces all the way back to the CPLD. If you cant tell I have a passme to look at for you. Do you understand? It's only six pads.

The_Legend · June 14, 2006, 11:04:47 PM

yeah, I understand what you say, but the chip connections are a bit different... let me show you a picture of my superpass2 (from now on, I'll assume it's a superpass2 =P)

If you take a look at the previous image I've posted, the passme one, you can see that the 2nd pad (southwest part of the chip, counting from up to down) has no resistor attached to it, while on my superpass2, there is. also, on my superpass, the fourth pad (same orientation) isn't connected to anything, but the passme is... I mean, maybe there's something different, I don't know...

But if you can trace that connection to me, it would be great! You see, that are some connection that are made going behind the image, and I just can't see only with this picture.

A scheme of thw connection of the superpass2 programmer would be better, I think, but anything you can do for me is already enough!

Thanks for all the support, dude! \o/

Don't worry about the resistor. What you need to worry about is the orientation of your CPLD, and how you're going to solder some wires to that small SMD device. The rest will work like passme1 instructions.

I'm going to take some better pictures for you . . .

BBL

I can always sold to the trace, lol =P

man, thanks again for all of your help!

The_Legend · June 15, 2006, 10:49:49 AM

So, would it be something like this?

See why I was a little bit worried? =P According to your diagram, the VCC pad of my chip isn't connect to anything at all... wouldn't be a problem?

Anyway, I'm gonna try this configuration, and hope it works =P. Thanks again!

Edit: Would there be any problem if I connect the TDO pad to the resistor? It would be easier, that way the only pad I get to connect directly to the chip would be the VCC one...

bitblt · June 15, 2006, 01:22:23 PM

Yes, try using the hole near the resistor. The VCC line was difficult to figure out. The trace leads underneath the CPLD. Try following VCC from your edge connector back to the CPLD. Also, you might want to check out the Gerber files for passme1. If you fail I have an extra passme1 I can send you. Good luck.

The_Legend · June 15, 2006, 03:41:50 PM

Well, I soldered to the golden connector, locatted on the bottom of the superpass2... my soldering skills are not that good, and I tried using the superpass program, no luck... downloading the WebPACK now (what a HUGE download! :oops:), gonna wait till it finishes to try out my luck again... but for some reason, I'm not that confident =/

If only I had received the passme instead of the superpass as I ordered... =(

Thanks for your offer, but if I don't get this thing to work, I'm gonna get the superpass2 in here (or passkey2, passme2, whatever is cheaper =P). My Lite is coming until next week, so I don't think I'll be able to wait for your passme arrive here, specially with the customs on strike, as I said before (it's been a month today that my MK2 is here in my town but doesn't get to me ='( ).

I'll post a diagram of how I sold the things, for now I'm just too frustrated to do so =(

bitblt · June 15, 2006, 04:01:44 PM

What did the Superpass2 software say? Did it give you an error?

The_Legend · June 15, 2006, 04:06:23 PM

Error! 1. Hardware not connected to PC.
2. USB cable not connected.
3. SP2 Key Switch not openned.

pretty much every error that could be, right? =P

I'm downloading the WebPACK now... so glad I updated my internet to 1 Mb, downloading that with a 256 Kb would be a pain in the a** xD

bitblt · June 15, 2006, 04:22:20 PM

That makes me think your CPLD isn't getting power. Are you using fresh batteries? Use a multimeter to check your soldering? Also, use the multimeter to trace VCC from the edge connector back to your CPLD. I doubt you have ruined your CPLD even if you did get something wrong. It should work if you experiment some. It's just a re-programmable CPLD. It's the same basic design for all pass through devices. Take a break and try again later.
