Here goes nothing!

To date the ProgSkeet v1.2 does not work (cannot program NAND or NOR chips - although some success has indeed been reported programming NANDs).

In my quest to get my v1.2 to work I noted that the v1.2 shares much the same hardware as the ProgSkeet v1.1 which DOES work. That is to say the ProgSkeet v1.2 and the ProgSkeet v1.1 shares a common FPGA, the Actel ProASIC 3.

Here I describe how I have turned my ProgSkeet v1.2 into a ProgSkeet v1.1:

Image below shows the ProgSkeet v1.2 board wired up such that it then 'becomes' a ProgSkeet v1.1. Unfortunately there is no getting away from the fact that I've had to add extra hardware in the form of a regulator and more importantly a USB driver chip.




To test my theory, I made a daughter board onto which I've wired my ProgSkeet v1.2:



So the million dollar question: Did it work??
After using my InJeCtuS to program in the v1.1 BitStream (ProgSkeet_Retail_Default111006.dat) and using WinSkeet111205 I attempted to dump and Program the NAND you see soldered to my daughter board.

So far, in dumping and programming a NAND chip... YES! Finally my ProgSkeet v1.2 WORKS.

TBD: Testing a NOR chip (thanks @Sarah1331 for sending me a NOR chip to test).

Hope this is of use to someone

Out of interest and so that the hardware of the ProgSkeet v1.2 can be compared against the hardware of the ProgSkeet v1.1, see my reverse engineering attempts of this hardware here:

Note: In using my ProgSkeet v1.2 as described in the post above, I did NOT change ANY of the resistors on the board - I used it as supplied (R8, R14 and R16 not fitted).

If it does all go ok have you got an estimate to what it will cost a customer to convert there progskeet 1.2 to a 1.1

And I believe you should have the sister board have drill holes where the pads of the skeet 1.2 are so less wires and a more secure connection you could call it a sister qsb lol

Let me think on this...

As shown, a USB chip is required, the basic cost is 94p, a USB connector is 58p and the regulator £1.14 (not including delivery etc). In fact a connector is not really required - a USB cable could be chopped up and hard-wired to the USB chip.

Don't really need the regulator either if 3.3V supply taken from say a powered PS3.

IF we were to make the daughter-board PCB to support this idea and supply it with components fitted, plus time to make and ship (to the UK, more for abroad of course) then I'd hazard a guesstimate at about £15 all-in for the bits and bobs (<- includes delivery charges) and then £15 for the bare PCB (<- includes delivery charges). No 'profit' in that of course

Sound reasonable?

'Customer' then gets the basic connection hardware onto which they place their ProgSkeet v1.2. Or just wait for a working BitStream for the v1.2 to appear.

Note: Connecting up to a single NAND chip is FAR easier than connecting up a NOR chip. If connecting to a NAND, don't need all that green wiring (directly to the FPGA chip) shown in the picture of my daughter board above.

woaw! the newest ferrari!!! Andy you are hugely awesome! and so reactive...i'm on the butt
now i want to know if i am capable to perform that modification...
before all, i go read your conversion document! and wait some's news about your NOR dump test.

I thank you for that job!

If you can solder 0.25 pitch freehand you piss this

Great job Andy , but I have a question :

What if we don't want to remove the chip , I mean we just directly solder the wires from the prog to the mobo, does it work the same way ? Because on the daughter board I see that we must remove the chip and put it on it , what I am saying is : is there any other design that makes progskeet 1.2 be 1.1 without removal of chip ? , just a normal 1.1 , with pinouts and support of the ziff socket ... Thanks

You don't remove Any chip

The daughter board IS as the ProgSkeet v1.1 - Look at the 4 sets of solder pads around the ProgSkeet v1.2 board - they are laid out exactly as per the ProgSkeet v1.1.

But while I was at it, I ALSO provided for soldering to a NAND flash chip (because I couldn't be ar$ed to do all that wiring to an in-situ NAND flash chip - so I removed one from a PS3 and soldered it onto my daughter board). So, if you understand me, NO you don't have to remove a NAND chip and solder it onto my daughter board and YES you can use the solder pads to wire to a NAND (or NOR) chip which is soldered into say a PS3 - i.e. just like a 'normal' ProgSkeet v1.1.

I mean we just directly solder the wires from the prog to the mobo, does it work the same way ?

So, to answer your question: YES

and support of the ziff socket ...

No 50 way ZIF connector on there though for 'solderless' connection at the mo'. Should I put one on perhaps?

I'm counting on the ziff socket actually , because I'm using this to wire the ps3:



It a header board that came with the nor clip , I use it instead of the pcb P's

Okies! Will add it. Guess it won't be complete without it TBH.
