Well, took me about 12 hours of pulling my hair out, but I got it.

First of all, the funny part. I spend about 8 hours trying to figure out why I couldn't get my BB Jasper to glitch, then realized I had a 512mb nand, not a 256. I had formatted the internal mem unit and it showed about 250mb free...so I figured I had a 256mb nand...lol. Not the case. I guess even after formatting alot of is still in use? Oh well. That was the first prob.

The next big prob was multibuilder 0.3. I tried multibuilder 0.3 and JTAG Tool 4.25, neither worked. Frustrated, I was convinced it was my wiring. So in the process of pulling off some hot glue, I ripped the pad off the FT67U point :mad2: grrrrr. Thank God for that alternate point under the heatsink on the top of the mobo. That worked.

Anyways, what did work was multibuilder 0.2!!! I don't know why nor did I investigate, I was just happy as sh*t to see Xell. (all other variables THE SAME...just used 0.2 instead of 0.3)

Next prob...crackling audio and freezing on bootup! :mad2: :facepalm: This was fixed by moving around the wires on the underside of the board and unclumping the wires near the coolrunner board. Basically separate all the wires from each other so they all have a clean route with no interference from other wires (and those coils on the board)

I did add the 0.068uF cap as suggested.

Working awesome now, glitches instantly 50% of the time and within 2 seconds the other 50% of the time!

Everything is working great, but I'll try out multibuilder 0.4 just for fun this evening.
Edit: multibuilder 0.4 created an image that works. Didn't bother testing the ecc glitch image though.

Hope this helps someone! :)

A 512mb Jasper will have just under 400mb free when the memory unit is formatted.
