Nice work :-)

Nice

JRoark · 2020-05-18 15:03

Sweet! You've been busy!

rogloh · 2020-05-18 22:55

Interesting. Once you add a loader to this Cluso it would become very useful for interactive control of different applications, even if there is no way back out except for pressing reset at which point it reloads and starts again.

If we always remain in SPI mode the SD card can hopefully be re-initialized over and over this way after each reset without needing removal.

Tubular · 2020-05-19 02:37

Nice work Cluso

Yes we do need to check out SD reboot

There should be no need to re-initialise the SD card, even if you access the Flash in between, so long as you leave the I/O pins tristated when Flash access is done. My SD driver always leaves the pins tristated after initialisation/readCSDCID/readSector/writeSector.

rogloh · 2020-05-19 04:54

Yes hopefully there will be a way to use both flash and SD reliably like this after multiple resets etc. Though if we change a card into SD mode it will stay that way until a power down I believe. For now we don't have SD mode drivers so it is not an issue. IIRC the P2D2 has the ability to power cycle the SD card so that could fix that issue too on reset.

Cluso99 · 2020-05-19 08:40

clear, del, diff, free, help, lf, ls, ren, testsd, type, used, ver all working

copy (not working - bug), reboot (not converted), run (not converted)

Note that I've removed the cpm routines for now.
Speed will need improving but that can come later.

Cluso99 · 2020-05-19 08:47

To permit the same SD card to be used on both P1 and P2 I will be using the following naming conventions...

.BIX for binary files (.BIN on P1) that can be loaded and run using the "RUN" command, and will overwrite the OS.

.CMX for the binary command files (.CMD on P1) for OS programs such as "DIR" etc. "RUN" is not required to run OS progams.

Currently on P2 they (.CMX files) are in the one binary until I work out how to load them. By residing in separate files the OS can easily be extended without recompiling the master OS file(s).

Cluso99 · 2020-05-19 22:24

DIRCPM working

This command lists the files within a CPM disk file held on the SD card.
In the CPM emulation, disks are held as a contiguous file (one per cpm disk drive) under the FAT32 file system. Each cpm drive (ie FAT32 file) is 8MB although some of these were created to be 32MB to permit possible later expansion in cpm.

Cluso99 · 2020-05-21 09:17

Here is x220

Compile OS2.spin with pnut

You will need to copy _HELP2.TXT to the SD card to get help.

Commands that require parameters have their own simple help by just entering the command without any additional parameters. eg COPY

Mike Green · 2020-05-21 14:49

Eureka! It runs. Thanx for posting the sources. Question: What short extension should we use for spin2 sources? sp2? For that matter, what 3-character extension should we use for spin. It would be nice for Fastspin and PNut to accept the short extensions as equivalent.

msrobots · 2020-05-21 17:31

sp1 and sp2 would make sense.

Mike

Cluso99 · 2020-05-21 22:58

For P2
.sp2 for spin source
.bix for binaries (_BOOT_P2.BIX and _BOOT_P2/BIY are used in the ROM) see note below
.cm2 for OS command binaries

Note: I saw Eric use .biz for an OS test he did.
We should choose just one of .BIX .BIY .BIZ BI2 now!

For P1 I use
.spn for Sphinx (P1 spin source files)
.sob for Sphinx (spin objects while compiling spin)
.tok for Sphinx (tokens while compiling spin)
.bin for binaries
.cmd for OS command binaries
.dsk for CPM Disks (will be the same for P2)

Sphinx is Michael Parks P1 spin compiler and OS that runs on a P1.
I have converted this to run on my P1 OS but it was never thoroughly tested

Postedit
Updated Sphinx extensions

For completeness sake, VentilatorOS additionally has .RAM for SPI RAM preload files - might be useful to have HyperRAM preload on P2?

Ahle2 · 2020-05-22 18:32

Cluso,
this is a really cool project. I will try it out!

Wuerfel, what is VentilatorOS?

My somewhat customized/improved fork of Cluso's P1 OS. [Relevant forum post]

(Also, while you're here, have you seen the cool Retronitus-related things I've made?)

Cluso99 · 2020-05-22 23:05

@Wuerfel_21
Yes, add any .RAM or whatever you need. Would be great to get a list we all can use

Unfortunately haven't had any P1 time to look and try your modified P1 OS. What you've done sounds great!
When I get a bit further with my P2 OS perhaps we can work to improve it. Currently there is no optimisation or much error checking. It's a very basic conversion of the spin but because I cannot get any info from Chip, I'm at a loss (without decoding pnut/spin) to get to the next stage. Meanwhile, I have plenty to go on with.

The only thing that I don't want touched (for now) is the SD PASM driver. There are a number of gotchas in there that MUST be obeyed or the SD card fails/locks. And there are a few things I want to add. But substitution of the driver is fine with me.

Currently the serial/monitor calls remain in the same position as the ROM calls, except for the cog register usage which has been mandated to move by Chip's pnut/spin2. The hub code positioning will change later.

Ahle2 · 2020-05-23 04:27

Wuerfel,
I don't have a P1 setup to try out VentilatorOS at the moment since I switched focus to the P2. But it sounds like cool additions to what Cluso and others have done. Nice team effort!

I have actually seen YouTube clips of your Retronitus compositions, but it's hard to tell what's changed just by hearing!

Since I left Retrontus in the dust, I havn't been following the thread much or bothered testing things out. The reason is that I got burned out three years ago and went home with sick-leave for a year. I couldn't think straight and I lost interested in all my "babies". When I got better a new shiny thing called the P2 layed on my desktop. End of story. (I am interested thugh!)

Can it still play this example tune I made for my latest release?

Not without some adjustments. Instruments need to be adapted to 64kHz sample rate and some data would need to be shuffled around a bit. I should probably do this at some paint.

This is stepping thru' the CPM BIOS as it prepares to read from the disk (SD Card).

Looks pretty neat, Ray. Will you be able to run WordStar on it?

Yes.
Wordstar already runs on my P1 RamBlade plus lots of the other CPM2.2 programs too, including msbasic. The RamBlade has 512KB SRAM and uSD and fits in a matchbox.

This is the forum link but lots of things got lost in the forum upgrades.

BTW heater wrote the Z80 emulation (ZiCog) for P1. My P2 Z80 emulation is based more along the lines Pullmoll did in his qz80 which is a more thorough Z80 implementation which includes many of the undocumented instructions.

My Z80 implementation is running and works up to reading the SD card. I have the SD card driver already working in a separate program, so it's only a matter of combining the two programs together now. I should have that done in the next day or so

@Cluso99 Up above you mentioned ".cm2 for OS command binaries". I was curious what the form your executables take. Is it CP/M-style where it's a single segment with a fixed loading location and entry point? Something more elaborate?

In my P1 OS each command such as DIR was a separate program that used a bios like resident code. That’s the same vision I have for P2 but it’s not there yet.
Each .cm2 would load into cog $0. They are compiled separately although they are aware of the resident hubexec code. This allows extension commands/programs without the need to recompile all OS commands and programs.
So it’s similar to CPM and DOS.

Standalone programs can be launched that take over the whole P2 - eg CPM takes over the whole P1 although my intention was to have CPM run as an OS command.

Propeller 2 OS - it's alive! And CPM2.2 is running!
