You've asked about time out in released cores - i've said there is no timeouts there.
Compilation and licenses are completely different things. End user should not worry about this.


Ok. I failed to mention I was reading the porting guide.

Oh ok.

In the core porting doc it says there is a timeout if you don't have the full development license.

Also, does HDMI still take a long time to compile?

Re: I/O Board

Is one of the primary reasons for the IO board to circumvent the one hour timeout on the HDMI and scaler IP from Altera? I believe the other one is that the HDMI IP also takes a lot of space and compile time. I guess I could also just plug into my monitors VGA autoscaler port... not many have those ...

DE10 Nano LTC 2x7 Connector

I've been trying to find a suitable ribbon cable for the 2x7 socket labeled "LTC 2x7" on the DE10 to do some hacking. I have a 2.54mm 2x7 ribbon cable but that doesn't fit. I think it must be a 2mm IDC socket. DIGILENT sells a 2mm 2x7 IDC JTAG ribbon cable for Xylinx boards that looks corr...

Re: RTC board

Okay. I see. The date-time service just formats the Linux date/time and passes it to the Minimig core, so you only need to change the Linux driver to support the new RTC chip. right. But i strongly suggest to use recommended chips. They are not hard to find and there is board already for them. Othe...

Re: RTC board

There is no book of documentation if you mean this. You can check hps_io.v signals. There you will find RTC info. It would be more clear if you would tell what you want to do. Are you writing core which needs RTC? Ok, thanks. I was wondering what would be required if I wanted to use a different chi...

Is this interface documented or should I just read the linux RTC service code?

Thx

Re: RTC board

Sorgelig, I was studying the RTC board and I'm trying to figure out how it works with the Minimig core. Obviously the M41T81 communicates with the Linux side via I2C. It updates periodically and via the hwclock command. How does the minimig pick up this date and time? Does it have direct access via ...

Re: SDRAM board (cap substitution)

I'm trying to acquire all the parts for a MiSTer. The first thing I looked for was the surface mount caps for the memory board. KEMET C0805C104J5RACTU Unfortunately everyone seems to be out of them right now unless I want to buy 4000. I looked on mouser and there's a very close match made by KEMET, ...
