Re: Minimig (Amiga) core discussion

Ok. Switched to my second MiSTer for testing. It's less perfect than first one. try this: Minimig_t3.zip i found that Minimig is starting to loose correct aspect ratio at start.. Probably i will need to change some code.. I do not see any problems with this version. I observed the wrong aspect rati...

If ok, then will go to release.


Looks much better to me. I have it running for at least half an hour playing around with sysinfo without any crash.
Currently I have no fan connected, with the previous release I could barely boot without fan.

Re: Minimig Core ROM.KEY Location

You don't need this file if you use plain Kickstart ROM. It's simply leftover from original Minimig. I even not sure if it still properly used. I would rather remove this encryption when i will revise this part of code. If You use the Kickstart-Files as they come from Amigaforever this file and the...

Minimig Core ROM.KEY Location

Hi, the Minimig Core has this useful feature that all Amiga-Files may go to the Amiga directory on the SD-Card. All files but one - the ROM.KEY file needs to be in root of SD-Card. With this little change in config.c (Line 73) this last file could go to the Amiga directory too: if(FileOpen(&file...

Hi, I did some experiments with this gcc Version: gcc version 5.4.0 20160609 (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.4) Some observations while building the MiSTer binary: 1. It throws a lot of warnings about wrong printf format parameters, some of them might cause trouble ... 2. Line 450 of boot.c caus...

Re: Testing: Support for more HDMI resolutions and other changes.

I don't see an attachment Strange - maybe is was too big? I did not see an error message. My Core is running now. I found the root cause. I had my setup running without the cooling fan. With the Fan running my self made core works fine. It looks like the video_mode feature in HDMI_Lite needs better...

Re: Testing: Support for more HDMI resolutions and other changes.

Not sure what you mean. Sometimes DE10-nano get screwed and needs cold reset or power cycle to get back to normal work. I did power cycle my board several times. I have the first version of my HDMI_Lite ZX (without video_mode) and this core still works. And the full ZX Core works too (in this core ...

Re: Testing: Support for more HDMI resolutions and other changes.

Lite revisions of ZX and BK0011M cores also have HDMI video. It uses simple scan doubling/tripling/quadrupling depending of original and screen resolutions using my new HDMI_Lite module. You can see a sharper picture in Lite revision but picture may not fill the full screen and can be narrower or w...

Weird.. My monitor shows different resolutions.. I just tried it using the new template MiSTer.ini and found that there must be some problem with the parser. video_mode=0 is only evaluated when there are less comments (only max. 5 lines) above the video_mode line otherwise MiSter says: "Incorr...

Well, porting doesn't mean copy/paste from MiST to MiSTer. It requires some work. Oh thanks I missed the hints in the Porting gui...

Re: Build Environment

I don't know why you are talking about Altera/Intel. Linux part has no relation to FPGA at all. It's pure ARM Linux code. Linaro is famous gcc releaser. They have have almost all gcc versions on their site. I don't have link to exact gcc version i'm using because i've downloaded it long time ago. B...

Re: Core porting questions

I am trying the only core I am really interested in, the Mist core (ATARI-ST). It will be a hard work. MiST core is similar to Minimig - it has very special support on ARM side. It also uses many custom commands over SPI. Although i've ported ARM part of MiST to MiSTer, this part of code was never ...

Re: Build Environment

C99 option has been added into recent commit on repository. Note: MiSTer is dynamically linked against libraries, so correct work is not guaranteed if you don't use gcc 5.xx. Thanks the Makefile works now out of box. I hope that the shared libs that are used are bundeled with the Linux-Distrbution,...

Minimig is pretty complex core. Not good thing for study. Look in something simple like ZX core.

Re: Core porting questions

SPI interface on MiST is used in user_io(mist_io), osd and data_io modules usually. You need replace these modules by hps_io from MiSTer. OSD is handled in framework - so simply remove OSD from ported core. So, SPI should disappear from ported core. If it still used in other modules, then it will r...

Re: Core porting questions

Hi, I somehow managed to compile the Mist core using porting guide. So far I have no IO-Board (hopefully coming soon), so no VGA-Output to do any tests. But I am sure it will not work because of the way the Mist wants to talk to the ARM. Currently Mist wants to use several SPI channels, but Mister h...

Re: Build Environment

Main_MiSTer is compiled by, let's say, random gcc version. I don't use Altera/Intel environment. So, any suitable environment is fine. You can use cygwin, mingw and of course linux. I'm using my own set of build tools including git, mingw and gcc. I'm using Visual Studio 2015 as IDE (hence you can ...

Re: Build Environment

It's always possible to use a VGA to HDMI adapter... not ideal but in the grand scheme of things, not having HDMI shouldn't be a bottleneck if you'd like to port or write a core ;) Maybe it should not be a bottleneck, but then I can stick to any FPGA-Board without HDMI too. I am quiet sure that as ...
