Re: MiSTer: MiST on Terasic DE10-nano board.

Care to elaborate, how close you got on the DDR3 version? it doesn't matter how close. Either it can or cannot. And it's impossible to make it faster or slower. If, for example ZX core cannot simulate original timings, it doesn't matter how bad some demos are. They are simply bad. bits per pixel? s...

Re: MiSTer: MiST on Terasic DE10-nano board.

Did you try already, or is it just a guess? may be it's just for fun i've went through 6 versions of SDRAM board and spent a lot of money instead of try on board DDR3. I know it wouldn't be easy, but then you have also the HDMI connected on the DDR3, which would allow much nicer resolutions and han...

i have around 5" LCD with HDMI input. It even powered from HDMI, so only single cable is required.

Re: MiSTer: MiST on Terasic DE10-nano board.

That's look strange.. I have 3 different hubs - all of them are working fine. Also i have friend with DE10-nano and his hub also works with my Linux.
May be we need to wait for more users to get more statistic.

In the mean time i've rewrote part of ZX core. Now it doesn't require SDRAM board.

Re: MiSTer: MiST on Terasic DE10-nano board.

However on the SD Card Installer Linux of the MISTer I get no USB at all. Strange - right? did you try only one HUB or several different hubs? Did you connect the HUB before you power DE10 or after? Is the arduino connector independent from the GPIO? If so... that might be a convenient place to put...

Re: MiSTer: MiST on Terasic DE10-nano board.

I think, in case of LPC (low pin count) bus like QSPI, it's possible to make an external connector where extensions will be plugged. Oh, i've forgot, there is already similar connector on the board. It's not QSPI, it's LTC. Kind of standard connector with I2C+SPI+1xGPIO. It's connected to ARM side w...

Re: Compatibility/accuracy database for FPGA cores (Not JUST Mist)

MiST is not abandoned. There are many cores on MiST board t enjoy it. But at the same time many cores hit the limits and cannot be improved beyond current state. In most cases the big problem is lack of FPGA's Block RAM. As you can see it's hard to fix the FPGAGen due to lack of BRAM. Same goes to a...

Re: MiSTer: MiST on Terasic DE10-nano board.

Actually OTG power output of DE10 has special chip which is supposed to handle over-current and other problems. So i think the USB host power is OK.

yes, both my HUBs get power from DE10. I've noticed that HUB is not recognized if plugged after DE10 boot. So, it's better to have it plugged before you boot DE10.

Re: MiSTer: MiST on Terasic DE10-nano board.

It's always possible to have different daughterboards for different purposes, although it could get messy to make cores recognize one versus the other. Perhaps four pins can be sacrificed to give a 4-bit identification number, so the cores can automatically know what is plugged? 40pin connector is ...

Re: MiSTer: MiST on Terasic DE10-nano board.

You need to use OTG cable to switch into Host mode. By default OTG connector in device mode.
You can look for specifically OTG USB HUB. Such HUBs have convenient micro USB plug.

I'd be curious to see if a C64 Koala pad would work with that arrangement.. it connects to the db9 but its not a joystick. Not sure about Koala pad itself, but if you want a pointing device for C64, then may be it can be emulated by mouse. Different retro systems have different I/O devices. One com...

Re: MiSTer: MiST on Terasic DE10-nano board.

@ijor, because I don't see it much related to the MiST. You have many Terasic boards but most likely don't have a MiST board. That's why you treat the MiST just like another FPGA board. You look at FPGA board only from HW point of view. That's where you're wrong and don't understand what's relation ...

Re: MiSTer: MiST on Terasic DE10-nano board.

I realize, but this is not much related to the hardware. You can have a compatible firmware in a completely different board, even using a Xilinx FPGA. I don't get your point of discussion. If you have Xilinx FPGA with MiST firmware then fine - use it. I've explained why it has this name and how muc...

Re: MiSTer: MiST on Terasic DE10-nano board.

The main relation to MiST is firmware and API. Although API slightly changed (to make it more advanced and faster) it's still the same at 99%. Binaries for different FPGAs cannot be compatible like it does between compatible CPUs. The only way to make binary compatible is to use exactly the same FPG...

Re: Compatibility/accuracy database for FPGA cores (Not JUST Mist)

You may look at MiSTer project. It's much more powerful. It's still needs a lot of work at least to port all MiST cores. Actually it's not so hard but still need some time.

Hmm.. music is weird after migrating ROM to DDR3. It seems Genesis is sensitive to RAM access time even for music. Well, going back to SDRAM. I was wrong. There are no additional issues while using DDR3 for ROM. It's just core itself has meta-stability issues. Actually this core has longest compile ...

Re: Genesis / Megadrive core ported to MiST

Notice ROM loading speed? Much faster than on MiST.

Also i've managed to re-make the core without using SDRAM at all. System RAM and Video RAM use FPGA block RAM. ROM uses DDR3 memory.
