Re: Original analog video without I/O board? Possible!

I wouldn’t mind buying a IO board but they are hard to come by it seems like...Is there a pinout schematic somewhere for the GPIO header for rgb and csync? You can use the schematic for the IO board. The one for version 5.6 is a bit easier to read, since it uses discrete resistors, version 6.0 uses...

Re: Faster USB polling: does the official update script provide everything needed?

I still have to make my own test rig (need a little MCU like an aduino, and open the controller you want to test) but I am hoping it is easy enough to document the process and allow many people to try. I would really like to know how the test rig works. I have a few USB controllers I would like to ...

Hi. I have a noob question. I assembled my MiSTer about 3 weeks ago. I'm loving it, to the extent that I'm now heading back towards the rabbit hole which is analog CRT displays - I haven't owned one for more than a decade now. Also, I live in the UK but am from the US, so SCART/PAL/50hz is new-to-m...

Re: Building Linux kernel

Hi! Is there any limitations to building and using a kernel based on the "socfpga-4.19-MiSTer" branch? Is "socfpga-4.5" still the "official" branch?

EDIT: Never mind, 4.19 is the official branch it seems, didn't read the thread properly enough.

You can't expect to get error free behaviour @167MHz, try 150MHz and below.

According to the MiST wiki, those cables won't work out of the box, but can be modded, at least for video.

Damn, I assumed that my adapters had the AG620x but they both have the CM6616, even being of this type (one with audio port), buyers beware:
