Cosmos won't boot successfully.

[piixx]

Just installed the DevKit over the UserKit. When I had the userkit installed, everything was booting and working smoothly. Realized I needed the DevKit in order to power on and off using ACPI and installed the DevKit successfully. Now, I can write code and all the dependencies are fine, but the VM just gets stuck on "Kernel Class Created" and does not continue. This is all using the default code:

using System;
using System.Collections.Generic;
using System.Text;
using Sys = Cosmos.System;

namespace CosIX
{
    public class Kernel: Sys.Kernel
    {
        protected override void BeforeRun()
        {
            Console.WriteLine("Cosmos booted successfully. Type a line of text to get it echoed back.");
        }

        protected override void Run()
        {
            Console.Write("Input: ");
            var input = Console.ReadLine();
            Console.Write("Text typed: ");
            Console.WriteLine(input);
        }
    }
}

Still no solution...

Is there anything being displayed in the Visual Studio Output window? I can see for sure there's definitely nothing wrong with your Kernel.cs so that's alright. Was it a fresh install (removed the Userkit first then installed devkit) or was it just an upgrade?

You can try cleaning the solution as that sometimes helps, and if it's just ACPI you're wanting to use for your OS in the time being, there's an external ACPI class that isn't part of the userkit which is where the devkit's ACPI class is actually from, you can find it at https://github.com/Arawn-Davies/Medli/blob/master/Medli.Hardware/Power.cs (I didn't make it, it's just a copy from that original code). Just remember to add it in a project that's in the HAL ring, and rename Medli to your choosing.

I'm not really sure what's going on here, kinda a noob just giving a bit of help, hope its alright :)

@Arawn-Davies

1. There is nothing (special) being displayed in the VS Output Window.
2. It was not a fresh install, as I do not know how to uninstall the Userkit.
3. I have tried making new projects and running them w/o modification to no avail. I'm not sure if cleaning will do anything, but I'll attempt
4. I might try the ACPI class, thank you.

OK, Uninstalled the Userkit using unins000. Made a new project and tried to run, got this error:

Same as #773

NEWS!!!!

Looks like all the commands actually ARE running, but the text itself isn't showing itself.

[Arawn-Davies]

The devkit has had some issues regarding SQLite as NET Core 2.0 I don't think includes the latest SQLite package which has the fix, I also don't know if this is caused by commit https://github.com/CosmosOS/Cosmos/commit/85cdb0f2c8ded9ae6ea0f24602b71da21fff42d1 so maybe try using the Userkit, doesn't have ACPI included and still uses Gen3 but is stable

[Arawn-Davies]

also, how are you able to tell that the instructions are running? Are you using the debugger alongside the Console methods?

[piixx]

Changing the foreground color changes the cursor color, clear() clears the screen still, writing a line makes a new empty line. Nothing shows, though.

[segg21]

@piixx you never showed enough of the stacktrace.

~Please install https://www.nuget.org/packages/Microsoft.Data.Sqlite/~

[jp2masa]

That package is pulled by Cosmos.Build.MSBuild, but the fix for the e_sqlite3.dll wasn't released in the latest package. It seems to me that the fix was supposed to be merged to the release branch in the Microsoft.Data.Sqlite repo, but it wasn't.

[segg21]

@jp2masa sorry, vs fooled me. What is said is wrong, my build still failed.

Gonna try rebuilding again :/

[piixx]

@LegitSoulja I have showed all of my stacktrace.

[jp2masa]

@LegitSoulja you're getting the sqlite error?

[segg21]

@jp2masa I didn't uninstall after installing the new release. I have SQLite in Cosmos\Cosmos\packages.

[segg21]

@jp2masa at first I wasn't, I created a new project to reproduce the issue, and now I have this error.

I had the kernel issue. Nothing wasn't outputting in console. Just says "Kernel Class Created"

[piixx]

@LegitSoulja @jp2masa If you build https://github.com/aspnet/Microsoft.Data.Sqlite/releases/tag/rel%2F2.0.0 and restart Visual Studio, you should be good. This worked for me.

[jp2masa]

@LegitSoulja I'll push a possible fix to a branch in a few minutes, you can test it?

[segg21]

@piixx If nuget wont work, this wouldn't neither. @jp2masa sure.

[piixx]

@jp2masa Does this also fix the not showing text issue?

[segg21]

@piixx I assumed the sql was the issue it wasn't. But idk. I was going to look into that, but this came up.

[jp2masa]

@piixx That issue may be caused by a PR that was recently merged. It changed some things in the console implementation.

[piixx]

@LegitSoulja yeah, same, but doing what i've said worked :/ i haven't had that issue in a while. Just the no-show issue.

[piixx]

@jp2masa was it the ascii extension thing? I checked that out

[segg21]

@jp2masa i'll check the recent passed PR's

[segg21]

@piixx interesting.

[segg21]

I looked at it, and isn't the ascii char codes wrong? @jp2masa @zarlo

I'll rewrite (We'll im going too), but these are wrong.

Edit: Nvm, it's my debugger that's not printing them correctly.

[jp2masa]

@LegitSoulja try the change in this branch: https://github.com/CosmosOS/IL2CPU/tree/sqlite-issue

[segg21]

@jp2masa ok

[piixx]

@jp2masa does this also fix no-show?

[jp2masa]

No, I don't know what may be causing it. Did you try installing a Dev Kit without the console changes?

[piixx]

@jp2masa ...what console changes

[segg21]

@jp2masa do I re-install devkit after re-pulling?

[jp2masa]

Yes.

[jp2masa]

@piixx https://github.com/CosmosOS/Cosmos/archive/9a76f82018b83d5c90cf7e190931c228a454f986.zip

[segg21]

@jp2masa No I don't. It's fixed.

[segg21]

@jp2masa edit: VMWare got an error saying the configuration couldn't be loaded. Tried to re-build, Error occurred while invoking IL2CPU.

Fine. I'll just re-install. Give me about 10-20 minutes

[jp2masa]

This is a weird issue. The error only happens sometimes. I think that I'll just add an MSBuild hack for now.

[segg21]

@jp2masa I think it's fixed now. I'll confirm after re-install the dev kit (As that may be an issue).

Then @piixx i'll look into the console issue.

[segg21]

@jp2masa yea, Error occurred while invoking IL2CPU now.

[piixx]

Can confirm @LegitSoulja that i'm getting error while invoking IL2CPU now.

[zarlo]

@piixx can you send us the build log

[piixx]

@zarlo I will later today if @LegitSoulja doesn't send it first. I have school to do :/

[segg21]

@zarlo I have no build log files, except for stacktrace in the console.

[zarlo]

that will work

[Remco123]

For me the no-show issue was solved by replacing the Write function in Cosmos.System2.Console.cs with this:

public void Write(string aText) { if (aText == null) { return; } for (int i = 0; i < aText.Length; i++) { if (aText[i] == '\n') { NewLine(); } else if (aText[i] == '\r') { mX = 0; UpdateCursor(); } else if (aText[i] == '\t') { //Write(" "); InternalWriteChar(' '); InternalWriteChar(' '); InternalWriteChar(' '); InternalWriteChar(' '); } //This fixes the issue else { InternalWriteChar(aText[i]); } }
UpdateCursor(); }

[Remco123]

But now the █ Char displays a ê

[segg21]

I like how an index of aText will equal \n or \r, or even \t. lol

[segg21]

@Remco123 But thanks for pointing that out. I was actually re-writing the entire Console, but I can't make further progress because I'm having other issues with Cosmos.

[Arawn-Davies]

@jp2masa I think this possibly confirms it was caused by the extended ASCII PR merge, @legitsoulja how's progress on the rewrite?
