MiSTer FPGA Forum

I think there's been quite some testing already. I'll put up a PR and see if Sorg would take it.

DD2 should work. It’s mapped basically the same as DD1 which I can test so I enabled it.

You need main MiSTer nightly, PSX nightly, and the kernel Sorg posted in the GitHub thread.

Pedals must be plugged into base.

From what I remember it does center by default when no FFB is active. Also there's n FFB driver for it. FFB only possible when connected to the xbox360 console. Should be possible then. Does anyone with this wheel want to try to pull debug info from Main MiSTer binary over UART and tell us what each of the axes and ranges are? In the main menu, Mi...

Any chance support for the xbox 360 wheel will be added to this feature? I would never usually spend money on a wheel, but found the 360 one at a goodwill for like $10 years ago. Works great on the 360/PC, would be awesome if it worked with the PSX core on Mister! Yeah I think it's pretty much possible. Do you know if the wheel centers itself by d...

That's a very cool setup! I have a dedicated driving chair and I have a Buttkicker hooked up to it so you can quasi-feel the road from the subwoofer sounds. It works better than one would expect! It also gives you a sense of force feedback from any game, just not from the wheel. I wish I had more room for a dedicated rig - unfortunately I have to ...

So, I got my wheel working as a proof of concept in the PSX core: https://www.youtube.com/watch?v=uTh8pJ7a_Vk It required some changes to the Main MiSTer input code but fundamentally this isn't a hard problem. My proof of concept would not work with anything except Fanatec wheels though but it would not be hard to add support for others. We are cur...

So I compiled the hid-fanatecff driver into the MiSTer kernel https://github.com/MiSTer-devel/Linux-Kernel_MiSTer/pull/24 and it works well in theory. All the axes are recognized and the buttons are working but it the analog axes do not quite map very well in the MiSTer UI yet. So I'm planning on making some contributions to the main MiSTer to map ...

I added the kernel and my MiSTer wouldn't even boot afterwards, that's before I've even had a chance to try and run the scripts, is there some other gotcha? Hmm... It really should not refuse to boot at all even if the higher frequencies are unstable. The kernel should boot at stock frequency and stay there. If you have your mini USB cable I'd ask...

So, more stability testing on the above. A few DOS games worked fine, and Windows 95 installed just fine at 112.5 MHz for me… but in the OS itself immediately it gives me a windows protection error! So it's not quite stable on my board. I think the best we can hope for in compiling with -C6 is maybe it'll make 100 MHz work for some more boards. I ...

When compiling with Quartus Prime targeting the 5CSEBA6U23C6, I’m able to get ao486 to run the DOOM time demo on my board at 112.5 MHz, which is the only benchmark I had time to run. This is going to be "overclocking the FPGA" but it is, after all, all the same silicon with different bins. 112.5 MHz: timed 1667 gametics in 1682 realtics 1...

I have a power adapter 5V, 4A. 400 MHz works as it should. 1000 MHz sometimes crashes, even for F9. 1200 MHz crashes when loading core or F9. I probably lost the silicon fight. :-( It's pretty crazy not even 1000 MHz works stable for you. That's not really a bump over stock. Seems like there's a lot of variation. If you have a multimeter handy I'd...

I'm guessing you lost the silicon lottery and your chip is just not stable at 1200 As Neocaron said can you try 1000 and 400?

Also remember it's only a 30% increase from the binned -C6 part with (as far as I know) identical silicon which has a 925 MHz core clock, a max Tjunction 15 degrees lower at 85C, and no expectations for active cooling.

I'd like to see my Fanatec DD1 working on it.

Has anyone tried just compiling the core targeting the 5CSEBA6U23C6 instead of the 5CSEBA6U23I7?

Hi! Has someone tried downclocking the ARM core? The best part of this is, for me, being able to keep my MiSTer cooler without a fan (I don't use any computers with fans, and my MiSTer is cooled with a good copper heatsink). Would downclocking affect CHD decompression on cores that use it like PSX, PC-Engine CD, etc? This driver already supports d...

Has anyone used one of those infrared laser thermometer things (with fan removed) to measure the temp before OC and after? I have one and I could do that, but its the cheapest one from Harbor Freight. I took my own temp with it and apparently I have hypothermia... I was going to get an ultra thin thermocouple and place it between the heatsink and ...

1.3 GHz is borderline and requires a slight 8% overclock or underclock on some other clocks including the cache fabric. I'd lean toward overclocking those at that stage. 1.4 GHz and 1.6 GHz crash my board instantly. Could still offer those as options for others to test if they are more lucky with the silicon lottery. Currently stability testing 1....

The Dosbox performance is also through the roof now with 50% more performance for a 50% OC! This is a game changer for the future and hybrid emulation! I didn't expect the 1.2ghz OC to be as stable as it. It's crazy. Wait a second Hi Coolbho3k, thank you for your work on this. I have just tried it to see what the performance gains would like with ...

I've been playing around with local MIDI on Atari ST, Amiga, and even A0486. With the 50% overclock MUNT is far more usable, although I'm still hearing minor timing errors here and there, so it doesn't quite replace an MT-32 pi. You can also try turning down the quality with "MUNT_OPTIONS = -n -l 1" in midilink.ini (disable reverb and lo...

This is cool! What's your heatsink situation like? It would be nice to use it as inspiration for improving my cooling setup too. *Currently, this will rarely keep the CPU below the max clock speed you set because the MiSTer process keeps one core at 100% load, so I haven't included scripts to configure this. This worries me a little bit. In past m...

Is the ARM chip part of the cyclone V itself? The thing we usually stick the heat sink on? If so, is there some issue where the more complex cores might be more likely to run into stability problems alongside this overclock? Like ao486, neo-geo, or psx. The ARM is chip is slow for MUNT and even fluidsynth has some problems, so AO486 is actually on...

With my DE10 Nano CPU overclock hack, using @bbond's DOSBox binaries (default profile) and the benchmark files found here: https://www.philscomputerlab.com/dos-benchmark-pack.html On the very first benchmark (3DBench 1.0) I get 16.1 FPS on 1.2 GHz and 10.2 FPS on stock (800 MHz). I think the increase is pretty linearly 50% as expected from the corr...

I released an initial version of my overclock. It's as easy as copying the new kernel file to your SD card and running a script. Not sure how to set up the hybrid emulation stuff, so if someone wants to try it and see the performance: viewtopic.php?f=27&t=4320

I'll be testing this. I hope we can eventually make the overclock permanent. It will be very easy to do that. You can run what the script runs every time the system boots. ie. just add the following line to /media/fat/linux/user-startup.sh # For 1.2 GHz echo "1200000" > "/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq" Ot...

Intro I've found a way to overclock the MPU subsystem (the Cortex-A9 CPU cores) in the DE10 Nano, and I've written a kernel driver to help facilitate it. You can try it out here. Why overclock the CPU? Overclocking should help with hybrid emulation efforts on the ao486 and Amiga cores Slightly reduce game loading times on some cores Will help with...

https://github.com/coolbho3k/socfpga_oc Just set CONFIG_CPU_FREQ=y , so the module in question should be compatible with my -4 kernel update. I tried git cloning and compiling his module it directly on my MiSTer, but it seems my -headers package is a little messed up as a result of cross compiling. This flow is supposed to "just work" th...

What are the OC capability of the arm chip on the DE-10? Anyone tried to give it an OC? Is that even possible? (I actually asked in the wrong topic, but that's relevant here as well I guess) :mrgreen: It appears possible, I’m working on it, and so far I’m optimistic. I’ve tested up to 1.2 GHz - a 50% increase - as well as a 400 MHz underclock - ha...
