Thanks everyone for the additional advice and comments, I will be taking them in consideration. I have also edited the price to be re evaluated for the time being. Again, this is a pre-production run to see how things go. Thank you.

I appreciate all the feedback and will take all your comments seriously. I think I've already addressed a lot of your concerns in the design, but I've edited the topic to reflect that this is a very small run of pre-production boards and that I'm open to any improvements and design changes. Thank you!

Update: After much consideration with talking to other members, as well as many feedback and improvements I have received, I have decided to to take everyone's advice and improve the product before any kind of true beta release. Thank you.

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 prog...

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).

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. ...

zeldaxpro 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 ...

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 g...

Right. I was just offering it up as a possible explanation for why your Xilinx programmer never managed to work over JTAG. Mine never did over JTAG either. Yours might have over serial like mine did. Oh ok cool. I still don't understand the 2.1-2.2v on Pin 1 and GND when connected. When I disconnec...

I never ended up programming with the Xilinx programmer and IMPACT. I followed happy_bunny's method on his website to flash it. It verified and flashed so I'm pretty sure it's good.

Yes, I have 2.1v there also. happy_bunny mentioned that I trace c_sel and clk for a good connection to the fpga. I built a 2nd Shuriken v3, so I may swap to that soon. Alright I should check my connections there as well. Is c_sel and clk pins on the FPGA that trace to what? And in regards to progra...

@zeldaxpro I think you and I are at the exact same point. I successfully programmed tonight with the same results. I checked the same points for voltages as you. If younare also following my other thread on assembler, you can see more details about how I programmed. (I know, I'm spamming alot) At t...

BUMP UPDATE: It looks like other people have been using this thread lol. I ended up making a new board, and programmed it successfully as shown: https://www.gc-forever.com/forums/download/file.php?id=2590 I seem to have another problem (hopefully my last). So I disconnected JP1 after programming, in...

Can you flash the .bit to the FPGA? You need to do that through JTAG and it will send the configuration bitstream to the FPGA. Once you power off the FPGA it "forgets" the configuration, which is why there is a flash chip to hold the configuration permanently. Are you trying to program th...

Hey everyone I'm back with an update and still can't seem to get a program successful yet. To eliminate multiple variables I have the board hooked up directed to a 3.3v and GND power source. I have JP1 connected. I checked the 1.2V regulator and it is working (1.18-1.19 reading). I assign a configur...

Did you measure pin 1? Yes, you can put 3.3v and program without the gamecube. I can't see shorts or anything wrong on your pictures. May try pictures on different angle where you can see that it's connected to pcb. http://www.gc-forever.com/forums/download/file.php?id=2209 Also check 1.2v regulato...

I still think there is a soldering problem somewhere. Perhaps try to gently tap all the pins on the FPGA to make sure all pins are connected. I make close up photos of FPGA pins and HDMI connector for shorts and bad solder joints and it works. Definitely use flux for the small pitch. I use wide tip...

So are you saying that it could of been programmed correctly already ... You can easily tell if it's programmed or not. I've done this 3 times (with shuriken video and original firmware) and worked as expected. You only need GND and +3.3 (if have more wires don't remove them) after that get multi m...

Two things: 1) Impact only programs the chip that you selected - from the log you probably clicked on the FPGA, but you should click on the flash chip (small rectangle above the large square) instead and select "Program" there. For me, Impact sometimes reports failure even then - it shows...

Use "Initialize chain" instead. Thank you Unseen and meneerbeer. I am making progress. I have shortened the JTAG wires significantly as I was doing some research and some people said do not have super long wires. I double clicked on Boundary Scan and Right clicked on Initialize Chain. I g...

Hey everyone I am back with an update and another problem. If anyone could help me out I would really appreciate it. Here are pictures showing up to the error. Just to note: 1. Gamecube is connected and powered on. 2. Shuriken Video is connected to Gamecube. 3. Programming wires are connected to Pro...

soldered wires are fine. Where did you get the programmer? aliexpress? Perhaps change directions and get one of these:Lcsoft CY7C68013A Mini Board I got the programmer from ebay. And I did see that but I did not really understand how to program it with that. Plus, the people that have successfully ...

Reinstall the drivers, change USB ports, disable driver signature enforcement sometimes I run into problems as well. Can I ask why you have wires soldered together for the JTAG connectons Ok thank you I will try that and see how it goes. You don't think anything is wrong with the programmer itself ...
