pong_ay38500_zxuno not compiled

[azesmbog]

It produces the following error:

ERROR:NgdBuild:604 - logical block 'MyCtrlModule/myosd/charram' with type 'DualPortRam' could not be resolved. A pin name misspelling can cause this, a missing edif or ngc file, case mismatch between the block name and the edif or ngc file name, or the misspelling of a type name. Symbol 'DualPortRam' is not supported in target 'spartan6'.

I think the file is missing in the project DualportRam.ngc

Is it difficult to add it for both projects?)) Thanks.

Hi, I added DualPortRam.ngc for both projects. Although, the ZXUNO core is not working. Could you try again?

[azesmbog]

I tried again. Yes, now it’s going well. But there was no image. I think a line error .v_in (videoc), you must either add a videoc signal or change the signal to video if you do this, the image appears, but shifted to the left exactly half the screen: (( https://s.micp.ru/z3gG6.jpg need to do something with the scandbler Here I am most interested in OSD and zpu-flex If I could figure out how to configure and compile it, then it would be possible to complete the CHIP-8 computer

I had this issue before and I could not solve it. I have no zxuno board and is difficult to test it without it. About ZPU flex I checked a webpage with examples to guide me. I would search it and let you know.

Here you have a tutorial about ZPUFlex, check it: [http://retroramblings.net/?page_id=1031]

I have a zx uno board. But I test the cores mainly on another board - AEON. There, in principle, there is the same xc6slx9 chip, but it’s more convenient to upload the firmware via USB. Well, and then, if you wish, I transfer it to zxuno. Rebuilt your core under zxdos, the picture doesn’t look very good https://s.micp.ru/p9mqC.jpg Well, I built my version, but with your OSD unit and zpu-flex https://s.micp.ru/MMPRm.jpg For the sample, so far I have connected only a reset signal, the rest I think is also not difficult to connect. I would like to make it work from the menu, and directly from the keyboard. But I did it to get experience with the menu and zpu-flex. By the way, in the zx80yunoV2 kernel, I could not download and run the files, but this is for another issue

Are you testing with VGA or RGB? I dind't get work the RGB signal. Try adjusting this +-1 with other values in module OnScreenDisplay.vhd. In the original module there is not that adjust.

--Señal VGA exacta -- xpixelpos<=xpos(11 downto 0); --Corregir pequeños desalineamientos si la señal VGA no es exacta --que se producen cuando la señal original del scandoubler no es compatible --completamente con la frecuencia de VGA if ypixelpostmp(0)='1' then xpixelpos<=xpos(11 downto 0) + 1; else xpixelpos<=xpos(11 downto 0) - 1; end if;

RGB or VGA? Sorry, but I do not know the hardware structure of ZXDOS. I have only VGA on AEON, and on ZX-UNO there is VGA and TV-out. As I understand it, a special cable is used for ZXDOS to connect to a regular TV via SCART? And for this they use 3 color signals plus sync with a line frequency of 16385 Hz? I specifically took a screenshot, and showed that I have a VGA signal

[avlixa]

For ZXDOS there is and adapter VGA to SCART using 3 color signals plus csync as you imagine. Sorry I didn't notice the configuration in the screenshot. Did you changed the "Design Goals & strategies" from balanced to Timing performance? I just test it in my ZXDOS and as it is in the project, with "Balanced" it looks good but with "Timing performance" it seems like you behaviour.

https://s.micp.ru/m7Cw5.jpg Thanks!!! Everything worked out for me !!! Now I will deal with zpu-flex. I have one global question - as I understand it, the kernel is built only in Linux by the makefile script. Can I build a kernel in Windows ?? If this is not possible, could you tell me which programs should be installed in Linux ?? I'm not a big specialist, but Mint can run :)

[avlixa]

That's great! Could you share your source code to update mine ? You also might publish a push request on this. About zpuflex you need zpugcc instaled, I only found it in linux and I don't know if it is available on windows. You should check https://github.com/zylin/zpugcc.git , although I was not easy to me install it. I am not specialist too. P.D: I sent you a message in zxuno forum about one of your cores, so check-it please.
