Hi, I was hoping to get this board for my Q, understandably it's a prototype so there's no guarantee.

I noticed on the J1 pinout, pin 4 should be to MOSI but, there is no connection to MOSI on pin 46 of the Spartan to Pin 4 of J1.

Even if I connect pin 4 of J1 to pin 46 MOSI, I'm unable to connect the CH341A, there is no detection. Do you have any advice or an update on how to use the firmware properly? Thanks

I'm not sure unfortunately, i haven't worked on this project in over 4 years, i'm not even sure i have the project files anymore

That's unfortunate, the Q isn't a great candidate for an internal HDMI mod, this solution had potential.

I'll try to solve it myself and post the results.

Looking forward for a solution too if it's a problem. This mod is perfect for the Q, wanna give it a try too.

Any chance you have the schematics on hand for this? or do you know if the chip is pin-compatible with the XC3S50A from the shuriken video schematic, Since I'd happily just remake it from schematic anyway and I'd be happy enough to share the creation back so the other interested folk here could utilize it

Hi, I've got a few of these boards on hand if you want a spare? I've had some progress with flashing this PCB but the Firmware I need is based on older versions like GCPlug v1.1 or HDMyCube's original version, I don't think the newer firmwares can be used with the SPI device used from these versions. So if you're able to make a more modern, working version it would be terrific! Yes the XCS3200A and XC3S50A do share the same pinout. I should have a spare Q mount that holds the PCB as well, this version isn't exactly a good fit to the OEM enclosure.

Perfect, that's all I need to know - I'll basically just be mirroring the existing shruken video schematic, and I'll aim to use the same chip as the gcplug(?? will research that part) so it should work without issue anyway. I'll work on it sometime this coming week, get a test board made up and if it seems fine I'll punt the proj and gerber files here so it's open source. I'll aim to have it fit in the footprint of the original board, though I don't see a world where I'm able to fit it within brass shield too, but should at least mount perfectly and somebody who knows how I'm sure can modify the existing 3d print pluto mount to fit (though the hdmi port won't be the same orientation as the pluto) :]
