gerber files for xblast lc4032 type modchip.
program lattice with xladdin xblast svf.
program 49lf080a with 512, 256, and xblast os = 1mb.
tested, works.
short s1 to boot 512kb bios, short s2 to gnd to boot 256kb bios.
cheers, internet world. hope someone makes use of these files.

A current limiting resistor for the LED.  

Depends on the specifications of the LED used what standard resistor value to use.

       Vdd - Vf     =     3.3 Vdc (pin 9 of LPC port)   -   Vf (LED forward voltage)
R = ---------------   = --------------------------------------------------------------------------------------------
          Isu                                            Isu (suggested using current aka forward current to operate the LED)

 

If you don't install the LED, you don't need the resistor.  All it shows you is that the modchip has power.

The LED is directly connected  to the LPC debug port's 3.3Vdc supply line through the current limiting resistor to ground.   Many Aladdin clones don't even have the resistor and LED installed.  Cost cutting build! :)

exactly. simply something shiny for people to look at.

Which SVF file did you use to program the Lattice LC4032V CPLD?

Which flash chip is installed in the modchip's socket?

Which BIOS did you flash to it?

Hey @KaosEngineer I used the xblast svf to program the cpld, it says it programmed corrected.
I use a STT49LF080, chip, first I tried to socket it, and later I solderd it directly, I tied the chip in a Aladdin, and it boots normal.

So I think its the svf file maybe, but I used it before to make xblast chips from Aladdin XT's.

The zippyshare file's no longer available.  Does anyone have a copy of it that they can post to a sharelocker site?

If so, post the link to it in this thread.

Hey @KaosEngineer Its also up on OSH park :

 

https://oshpark.com/profiles/gothkar

I am not 100% the same but i have to check tonight if is still have the original.

Do you have a copy of the xblast sfv maybe my got corupted, last time i also had a problem with other files on my drive
bing corrupt.

I believe I found a copy of the zippyshare file on my other computer.  See attachment below:

Hey @KaosEngineer

 

I programmed the chip again with your xblast sfv.

but still no joy, the chip still is not working, i begin to think there is something wrong with the boards or the lc4032

The 49lf080a  works if i put it in an aladdin XT chip, so thats good. the LC4032 programs okay without any error.
I have checked everything for continuity and i dont have any bridges or lose pins.

i am at a lose if anyone have any ideas please let me know !

I haven't had any luck with flashing Aladdin's to xblast. This is from one of the Facebook groups, maybe you printed the version without the fix?

Thanks @madmon I feel like a idiot, because of the white boarder around the holes for pinheaders I thought I should be solderd there.

 

now it is working!

Wait, you soldered the pin header on the wrong side of the PCB, removed it and soldered it from the bottom side and installed the modchip and it works now.  Or, did you have to add the wire that @madmon's picture shows?

I think he just flipped the header. That facebook post is a bit older so it might have been an older pcb design

      Hello all.
      I'm a new member of the forum and I have been playing around with the OG XBOx for a couple of years now. I never owned an XBOX before so my knowledge of the history is relatively limited. I do enjoy the versatility of the original XBOX, and I am amazed by the huge community and custom stuff that exists out there.
      Some of the machines I acquire (~40%) come with the modchip installed, but still have the original HDD. In the past, I removed the modchip because I could not find any info about it, and proceeded with a softmod, disk upgrade and so on.
      However, after I discovered this forum, I am having second thoughts and I am thinking maybe it is better to keep the modchip and follwo a differen approach.
      So, the question is, if there's an advanctage of the old modchips (probable Alladin II, I think) versus the more recent softmods. 
      thank you very much in advance!

      I have a xbox 1.0 here that fragged the day I got it. I thought "oh HDD probably died I'll just install a modchip". Well after installing said modchip I'm still met with 3 power cycles and the red and green lights with no error codes. Ive checked my soldering, checked that D0 is grounded, checked all caps, I cleaned the board after removing the clock cap, inspected traces for any signs of trace rot. Are there any caps that could go that just wouldn't show any sign of swelling or leaking that could cause issues?

      I could use some guidance here as I'm feeling rather dumb. I see plenty of forum posts about how you can simply boot up an Xbox with a modchip (D0 grounded), swap modchips, and flash the 2nd modchip as a means of fixing a bad flash. I'm trying to do this with a Duo X2 Lite chip that has a bad bios flash on it and every time I go to flash it, the app I'm using says "flash write protected" or something similar. Basically, the end result is that it can't flash the Duo modchip that I swap in. I've tried several times using different timings and different flashing apps (chimp vs evolutionx). Is there some obvious step I'm missing here? Should I be booting from a disc (hexen)? Loading into a special/BFM bios first?
      D0 is grounded to a screw mount. I'm sure it's booting from LPC.
      I'm booting with an OpenXenium, then swapping in an X2 Duo Lite (bad bios flash). I flashed a debug BIOS onto it first to use on my DVT4 kit, then later I flashed Yoshihiro's debug bios (which I found out is not actually not meant for debug/dvt consoles). I then used the 5849_Recovery disc to try and flash the modchip back to the official debug bios, but that bios is 1MB in size (2 copies of the identical 512KB debug BIOS), whereas the Duo X2 Lite can only hold a 512KB BIOS. So I guess it failed part way through? I have other modchips, but they either aren't compatible with the MCPX2 found in dev/debug Xboxes or aren't big enough to hold the 512KB debug BIOS.
      I'm basically booting with OpenXenium, then getting to my dashboard (XBMC), then loading Chimp. If I swap the chips prior to Chimp starting, Chimp just fails to start. The Xbox just freezes on a black screen. If I swap the chips after Chimp loads, it says "flash not writable" (or similar message). Same experience with evolutionx. The BT point is soldered on the Duo X2 if that matters (to enable always-on mode).
      Any tips on what I'm doing wrong or steps to try? Is my X2 Duo just screwed? Should I be using a different modchip other than OpenXenium on first-boot for some reason?
      By the way, the whole reason I want to flash this Duo X2 is to get my DVT4 kit back up and running. It has a bad TSOP flash (came to me like that). I might skip all this and focus on figuring out how to fix the TSOP, since using the Duo is just a bandaid fix anyways. I've already tried splitting the TSOP and that didn't help so I'm not sure what to do next other than desolder the tsop and program is externally... and I don't have a hot-air rework station anymore, nor a programmer.
