Raven. A homemade Atari-like computer

[agranlund]

Maybe I don't quite understand how to use it, but I don't have the Emutos window that you have.

- Program rom simm with "rom_con.bin"
- Connect the serial cable to the second serial port instead of the one you had it in before for those first boot messages.
- Set baud rate to 9600 baud
- Start raven

Does anything come up in the terminal?
(You're not going to get nicely formatted and colored EmuTOS output with CoolTerm like in my screenshot but that doesn't really matter, you still get text - I used another Mac terminal simply called "Serial" which supported such features)


What you are trying to work out is if EmuTOS is able to boot at all.
The black screen you had with the normal rom can mean anything. It is probable that it is related to ISA/gfx access but you wouldn't be able to know for sure at this point, for all we know it could be locking up or crashing even before trying to init graphics.
Testing if EmuTOS runs over serial connection, with graphics taken of the equation, would be one way of gaining a bit more knowledge on the matter.

The next step would be to run the old debug roms that you suggested from way back in the thread covering oldskool's bringup, and look at the output from that. EmuTOS communicates at 9600 baud on the second serial port already so you don't need new builds of those.


Btw, would you mind make a separate thread for the luciodra build of the Raven? I think general things, questions and help fits well in this thread but build troubleshooting and especially bring-up can easily generate many pages and I'm not sure it's the best idea to have everyones of that in the same thread.

I'm (very) slowly but surely trying to organise a binary release zip rather than having binaries scattered all over the place.
(and removing binaries from the source tree as they move into release package)

https://github.com/agranlund/raven/rele ... .A1.latest

At the moment it's mostly just firmware files and roms.
It will soon(tm) also contain a minimal software setup with drivers and tools but that part is not ready yet.

Documentation is lacking too of course but at some point it would be nice to have some sort of quick-start guide;
- firmware programming
- rom programming
- bring-up procedure
- software setup

[agranlund]

Perhaps not the most interesting from a user perspective but the monitor has just learned how to disassemble.
This will for sure come in handy when investigating crashes and such!

Some simple breakpoint and step functionality could be interesting to have too. later.

Binary releases now includes a small software distribution.
It's all work in progress and there's a small textfile with some info included.

https://github.com/agranlund/raven/rele ... .A1.latest

Ravens xbios extensions lives in the auto folder out of convenience for now but will move into ROM at some point.
If you had 060sp.prg in the auto folder since before then you can remove it since Raven has the same functionality built in.
Press delete at the boot logo to enter setup.
A bunch of settings are placeholder and not yet implemented but you should be able to modify time/date/language as well as all of the NOVA graphics settings.

That software package makes it indeed much easier and nicer.
Works great (on my ET4K).
With my W32 at startup it sometimes crashes at the Atari logo (freeze) especially at cold boot and still the garbled screens when moving stuff.

Would it be possible to add the 320 resolution as standard in the distro for Castaway and so?

Oh, that's a great idea!
And also the 720p resolution since most monitors are widescreen nowadays.

[Oldskool]

Awesome!

[agranlund]

@Oldskool , I've added some useful resolutions to the cards that supports them but I've only been able to test on Mach32 and ET4000-T8 myself.

Code: Select all

1280x720 : All cards except ET4000-T0 and ET4000-T4
 320x200 : All cards except Mach32/64

[Oldskool]

Thanks. Great. 720 looks really sharp indeed.

320x200 : All cards except Mach32/64

Oh, so Mach64 really can't support 320x200? I have been wondering why there is no such resolution in the basic package (it makes it very hard for stuff like emulators as they have to use double pixels then...)
