AladdinXT Conversion for Lcd

[Ryzee119]

Hi all,

As a fun educational exercise to wanted to replace the CPLD logic on the cheap AladdinXT 4032 Original Xbox modchip and convert it to a basic LCD driver, consequently it looses the ability to load a custom bios. I consider this to be something like the old X-addons generic LCD-display mods (but a fair bit simpler)

The Lattice LC4032V CPLD on the cheap Alladin modchips is extremely limited, so this is a hacky bare minimum to reduce macro-cell usage to fit onto the CPLD. Therefore it can't really support any extra functionality over the bare minimum.

It doesn't support backlight control (just full brightness always)

It has some very basic contrast PWM control through the dashboard settings.

Anyway just wanted to share what I came up with

Ideally, you could design a small PCB (and maybe use a larger CPLD) to improve the installation. that is something I may do in the future

This project looks very interesting but sadly I don't even understand half of what you are talking about.

I read the instructions and step 2 & 3 are in perfect chinese for me:

1. JTAG PROGRAMMER: Model ? Picture ? Where can I buy it: Amazon ? Aliexpress ? Link ?

2. APPLY 3.3V POWER TO THE ALADDIN PCB: From where: Motherboard ? DVD Drive ? Xbox Power Supply ? Picture ?

3. PROGRAM CPLD: What's this ?

4. UrJTAG PROGRAM: Will it work on Windows 7 Home Premium 64bits or I have to go back to Windows XP ? How to use this program ? I only found this video from 2015:

https://www.youtube.com/watch?v=So1N9FlPGbw

... do I have to do something different / add another step ?

5. COMPATIBLE PROGRAMMING CABLE: Picture ? Where can I buy it: Amazon ? Aliexpress ? Link ?

6. The light gray cable you are using is 30AWG ?  28AWG ? 

Feel free to be as detailed as possible.

I apologize for all the questions. Better be safe than sorry.

Thanks

I got 3.3v from a bench supply but you can get it from the xbox if needed. Up to the hobbyist. 

28awg wire will do.

What is a CPLD? Did you try google? https://en.m.wikipedia.org/wiki/Complex_programmable_logic_device

See this too. It tells you the required operating system, supported cables etc. http://urjtag.org/book/index.html

This looks like a good weekend project for my Aladdin XT on v1.6

I can not run urjtag.exe. Maybe there is another program?

Why not?  What error do you get?

libusb0.dll
I'm pasting into different folders and then nothing. The same mistake ...
I have windows 7 64 bit

:((

[KaosEngineer]

Try installing the libusb-win32 v1.2.6.0 drivers using the Zadig_wdi installer

https://sourceforge.net/projects/libusb-win32/files/Zadig_libwdi/

I cannot test if this works since I have no USB JTAG cable to try.

Update: I do see a 2.4 release of this installer available at the dev's web site:

https://zadig.akeo.ie/

Thanks to help! Witch https://zadig.akeo.ie/   libusb0.dll is ok!
Now ftd2xx again ...
you can go crazy with this

Ufff ... ftd2xx.dll I threw into the SysWOW64 folder and it works!
Soldering tomorrow morning, today I'm torn my nerves :))

Glad you solved it. I don't recall having to do any of that stuff just extracted and ran.

I had to install Quartus II programmer for the USB blaster drivers though.

[eustachy1973]

My windows 7 is modified. Maybe it lacks some drivers.To which directory should I upload the ALADDINLCD.SVF file?
In the console I have to indicate where the file is?
For example c  / ALADDINLCD.SVF etc?

Placing the svf file in the same directory as jtag.exe will be the easiest. Then you can use the command as shown in the github instructions

Now the matter of the chip?
I have old chips from 2005. They're ok?

My code was designed with the cheap clones in mind you pick up from eBay nowadays

I dont know if they will work with my code as the pins being used could be different. Id recommend sticking with the clones.
