Program Shuriken Video V3 Please Help!

Is it for sure supposed to read 3.3v when running normal? I thought that 1.8v - 2.2v was expected.

Yeah as far as I know. I've talked to 3 members, and another actually checked his PIN 1 (since he has a working shuriken v3) and it reads 3.4v, which is what it's suppose to be. As far as the info I gathered, 2.1/2.2v means there's a short somewhere, or an issue with programming, or bad soldering job. I'm almost certain its not programming for me because it flashed and verified successfully with the correct file for my FPGA. So I'm thinking either a bridge on FPGA or not a good connection due to bad soldering. I contacted happy_bunny to see what he thinks but he hasn't responded to me. Maybe you will have better luck. If anyone else knows more any information would be appreciated! Thanks.

Possibly related, but I can not be sure. There are 2 pads on the underside of the Digital A/V port, that seem to be easily damaged when removing the original port, for the Shuriken. These two points were damaged on one of my Gamecubes, and they disabled the video. I ran jumpers from them to points on the Gamecube mainboard, and it repaired them. I do not know if they would fix the voltage issue, but these are at least 2 points that I can help you check.

Check if this...

Hello, thanks for the advice, but that wouldn't be the issue for me figuring I kept the digital av port intact and just had wires going from the connector itself (it's my test GCboard). So nothing like that could of happened.

This is a dupe that I posted on assembler, but it does complete my comments in this thread as well.

I have a working Shuriken V3 tonight.

My problem from day 1, was physical orientation of the direction for R2 and R3. I fell for the same mistake on each board I built. Please review below.

My brain coasted over R2 and R3 for all 3 Shruiken V3's that I built.

I believe that I can see what caused my brain to be tricked. The orientation of the Text for every Resistor and every Capacitor, matches the direction of their corresponding component, except for R2 and R3. Their component is horizontal, while their text is vertical. A lame excuse I am sure, but as you can see I fell for this simple oversight 3 different times, each spaced weeks apart. I did not build each of these on the same night. Nor did I refer to my previous work. I just sat down on separate occasion and assembled them.

So it is of course up to you, but I would recommend rotating the orientation of the text for R2 and R3.

I believe this explains why I failed to program via JTAG, and why pin 54 never went high after Direct SPI programming. I was absolutely mistaken when I claimed it went high in an earlier post.

I am looking forward to finally moving forward and trying this out. Thank you for all of the help between this thread and other places.

Hey guys I have been away for awhile in trying to make a successful, working Shuriken V3 board. I made another board and same result... 2.2v on PIN 1. What am I doing wrong I don't understand?

1. I double checked the components used, brand new from Digikey, stenciled the board with solder paste,
2. Reflowed the board with my reflow oven. Physically everything looks good.
3. Used my magnifier, did not see any bridging.
4. Programmed the board by powering it 3.3v and GND, LCSOFT method. Programmed and verified as stated in the command prompt window.
5. Connected the board to the gamecube. When I power on the GC and plug in HDMI, it shows its detected on my TV, but no signal.
6. Pin 1 reads 2.2v and I do not know why.
7. I tested for 5v from the 12v to 5v reg, as well as the 1.2v reg. Both are fine.

Could it be the actual PCB board itself is messed up? This is my 2nd board and same result...2.2v. Should I program the Shuriken video board with it connected to the gamecube? (and have Pin 1 disconnected I believe).

If anyone can help me out I would GREATLY appreciate it. Thanks!

Are you able to try a different Gamecube?

Yes I tried 4 different ones. Same result. 2.2v on PIN 1 when having it connected to the gamecube. When it's not connected and just powered by 3.3v GND, I get 3.3v (3.43v to be precise).

Pin 1 appears to connect directly to the FPGA at it's PIn 3. Could it be bad programming?

I forgot if we have gone over this before, but have you checked if FPGA Pin 54 goes high to 3.3v ? If so, that would mean the FGPA is programmed successfully. However, I don't know if that means if it was programmed "correctly". But it's still the FGPA's way of reporting "I accept the code you gave me, and I'm ready to do what it says."

So I guess the question I have then, is can the FPGA be programmed incorrectly in a way, that would influence it's Pin 3 to drop you down to 2.1v ? I am wondering if you are thinking that you are programming it right, getting a "i'm good to go" reading at Pin 54, where in fact it's still programmed wrong.

Just taking some guesses.

No I know what you mean. I followed the LCSOFT method direct SPI programming that happy_bunny mentioned. I have a pic. This is the s200a chip, not the 350a chip by the way. He emailed me the bin file, maybe I can try to make my own with the latest GCvideo. Pic of programming:



I will check PIN 54 to see if I get 3.3v. I will check both with powering it separately and then connected to the gamecube. Anything else you or anyone here can think of? Thanks!
