Hi, I am trying to figure out this schematic, it's been a few years since I had to read one.
IPB Image

I just wanted to confirm am I planning this right?

D1, D2, D3 connects to the glitch chip and also the corresponding resistors.

The resistors are then connected together.

Pin 18 is then connected to the joined resistors.
Pin 18 and the joined resistors are then connected to GND on the chip

Pin 8, 11 and 12 are connected

Pin 13 is connected to R4. R4 is connected to TDO and also R5. R5 is then connected to VCC.

looks like you got it. I have a pic of mine here: http://unmrkd.net/heavenlymodz/uncategoriz...h-all-you-need/

thats actually beautiful.

yes that is the way to do it. look like mine.

Will this work with TX Coolrunner?

Unfortunately i cant seem to program my matrix chip tho... using 360glitchip programmer v1.1 instead of iMPACT... I think it could be that my 3.3k gold strips are not facing the correct way, but not sure...

Will not matter, resistors are not polarity sensitive unlike diodes.

I want to know about whether this will work for the new coolrunner, too.

Just ran it through iMPACT, here is what its showing me...

Ive followed the schematic to a T and shortened most of the connections, still unsuccessful...

I had that issue. I removed the diodes and resistors except the 3.3k and it worked. You can try that. I have that diagram on my guide on my site. I did it as a last resort. my LPT port doesnt like it when I add that stuff on my cables for some reason

Guess thats worth a shot, I just keep the 3,3ks' in the same position but remove the 220 and diodes?

Shintax909

Nov 10 2011, 10:59 PM

Worked like a charm! Removed the diodes, didnt have to remove the 220. Good job Antman1! Great tut btw!

thank you. Glad to help.

how come everybody is doing lpt, why not usb programmers?

its coz these diagrams assume your lpt port is 5v but some lpt port is 3.3v. u only need R5 3.3k in that case

Price. I think the cheapest usb programmer for the Xilinx CPLD is about $50, whereas the diy LPT cable is almost free.

What Value is R4? is it just 220 ohm or is there a 220R value? can't find it at radioshack.

Lpt jtag programmers are so cheap to make, and they only take 2 seconds to program a coolrunner. No need to use USB to program a coolrunner if you have an lpt port.

Thank you Antman1 and Shintax909 for the tips, remove the diodes make everything work perfect.

One question, do I need to keep the Matrix Glitcher 360 solder to the 360 board all the time to keep RGH to work?

i think you do (atleast CR needs to stay, so i presume every chip has to stay)

anyone has a nice clean guide how to make jtag cable and a cable to program the chip? most of the guides presume you already own the cable, or have the know-how to do it from listed materials.

Can someone post me a parts list to make this cable? Please reply soon.
