So... I bought an USBGecko and used it a lot, thanks, Nuke, thanks to all developers here in the forum! I like it... But there is a little problem: it doesn't work properly now. Dunno why. I cracked it up and searched the capacitors/resistors in my lab ;-) Maybe one has burnt ^^ Nevertheless it would be easier for me to repair it, when i had the circuit diagramm. If someone could draw one, it would be great. No, i don't want to sell it to _anyone_. That's absolutely not my intention neither I am selling homebrew to anyone (even noobs....). It's just a "repair intention".
Thanks in advance. everything i killed i managed to repair, therefore i wanna to try it in this case, too :-)
USBGeckos are very expensive here and i don't want to buy a new one; maybe all chips are ok, only a r/c is burnt...
what were you doing to crack it?
Mine opened on its own, the glue wasn't enough.
probably nothing.

same.
@millw0rm:If you can't fix it click the banner in my sig, (My friend is doing this) do a ton of servays then cash the point for ebay gift cards, then buy a USBgecko off ebay
matt, can you take it out of your sig, I don't want people being tricked in going to a scam site.
There is always a catch, no matter what they say :|
no, theres no catch. (see every point some one earns they make twice that in USD, from the servay sites that that person did so...)
You really don't get it, do you? ^^ I want to have a simple circuit diagramm lol
That's a thing of a few minutes (drawing etc..)... so c'mon :D I won't buy a new. I will _repair_ my old. That's it.
see, none of us are risking to open it up because honestly, you cant get a new one. and nobody wants to be without their gecko.
ask Igglyboo to, he's got 2...
Ömmmm....
It is not Solit nor bolted. You can open it easy with your Fingernail.
And Amazon has so many, the sell it.
huh? Why risking? There is no risk, when you meter your usbgecko (pin to pin ^^). there are 2 screws. screw them up and get ready to meter. there are no risks... In case of total damage: i have dumped the Flash of the (EEPROM?) of the ICs via a flasher as*.bin File. I could reflash them if needed...
IgglyBoo, please help :-)
USBGecko has screws? :\
sorry, this was my memory card ^^
The Altera Max II code is code protected, once programmed they cant be read back. Your best bet is contact the store you bought it from for a replacement if its broken.
As for circuit diagram, the parts are all off the shelf parts, so pin outs are included in the data sheets.
that means....?
Can you give a circuit diagram or not? ;-)
hehe
But, who wrote the Programm for the ALTERA MAX II? You, nuke? I would be happy, if we could have a talk about ICs programming and so on. I am very interested!
yep, i wrote the code, its written in VHDL, although i use verilog nowadays as its much more like C and prefer the way blocking and none block assignments are done.
So it's actually a Translator (what does the FTDi chip do?) between EXI->USB, isn't it, Nuke? I want to code it, too (as a practise). For any upcoming help from your site I would be very grateful! Thanks. (The Programming Language is VHDL? How can I prgramm the IC? I need a flasher (lpt printer port 0x80 Win32), where are enough pins to put the ALTERA MAX II in, right?)
Thanks for your help, Nuke!
(you can also PM me, if you don't want the forum to read "secrets" ^^)
Nuke, I found this: http://www.gc-linux.org/wiki/EXI:USBHostAdapter (http://www.gc-linux.org/wiki/EXI:USBHostAdapter)
It's the same attempt. How Can I programm the ALTERA MAX II IC myself via Verilog?
EDIT: Here the circuit diagram for all interested; a friend of mine "draw" it. Final Version (*.cct) will come...
If you want to practice learning hardware, your best bet is to buy some books on VHDL or Verilog and buy a cheap demo board. Start small and flash some LED's then work from there.
Like any programming language, in fact any hobby for that matter there is always a learning curve and you can't run before you can walk.
There are no secrets, its just a matter of understanding how protocols work, and how to glue them all together.
I have no plans to release codes to the hardware, So if your gecko is broke, then you should contact the store for replacement.
ok... but how did you find out, how/which protocol is used? I think EXI<->USB, but HOW it works?!
I used yet another gamecube documentation for info on EXI registers, wrote very simple test programs for sending, receiving a byte of data and a hardware logic anaylser for debugging, watching the signals.
hey~
actually you did give permission for the source code, nuke ;)
So.. Why's www.usbgecko.com (http://www.usbgecko.com) down (here it is o0)
Do you want to leave the wii homebrew scene (or you did already, didn't you?) Why, give a reaon! You're such a good coder! Without you BootMii wouldn't even exist 2day.
The codes are up on
http://code.google.com/p/usbgecko/downloads/list (http://code.google.com/p/usbgecko/downloads/list)
it may be the ones you needed now.
