nLaunchy 2.6

[Excale]

I've released nLaunchy 2.6 today.

Source and downloads here: https://github.com/Excale/nLaunchy

New features:

• OS 4.0.3 support
• Ndless 4.0.3 support

Not changed:

• Boot2 3.1 required (HW-rev < J)
• You get reboot-proof Ndless
• Cleanup of some useless files
• Green touch: reduces battery consumption of some recent OSes.
• nLaunchy any compatible OS

Removed:

• Some older CX OSes patches are not included by default anymore. Otherwise, the file is too big and leads to a crash (feel free to fix that). The code is still there, just '#if 1' your OS.

So, this works to put a 4.0.3 CAS on a 4.0.3 non-CAS nspire? I've been attempting this, but I keep getting the same results as:

Test 2 (CX non-CAS, HW-C) : Fail (stuck at the clock screen) Edit: Success now after cleaning (diags and/or battery removal for a bit)

I'm not sure what "Success now after cleaning" means, but I've tried the diags and/or the battery removal and it is still stuck on the clock screen. Any suggestions?

No this is not possible.
Such support is broken due to changes from TI after OS 3.2.4.

Since then, current Nlaunchy maintainers have never tried to fix this.

People who want proper OS 3.6+ support in Nlaunchy will apparently have to fork the project and fix it themselves.

Since then, Nlaunchy maintainers did never try to fix this.

Or rather, neither them, nor others ever published the easy patch which makes it possible to do so.

Okay, I understand. Then why does it say on the github:

NOTE: Not all TI-OSes are compatible with nLaunchy (but many are). OSes 3.1.0.392, 3.6.0.546 and 4.0.3.29 are. For a full list of compatible OSes, check src/patch.c

And in patch.c:

Code: Tout sélectionner

        case 0x1038C290:    // TI-NspireCX-4.0.3.29
            patch_CXNCAS_4_0_3_29_extra();
            addr = 0x109BE978;
        break;
        case 0x1038C7D0:    // TI-NspireCXCAS-4.0.3.29
            patch_CXCAS_4_0_3_29_extra();
            addr = 0x10A209E4;
        break;

If you prefer so.
Neither current Nlaunchy maintainers, nor other *competent* developers.

And I'm not considering myself as a competent developer in the context of Nlaunchy.

Well, in a way it's true that OS 4.0.3 for example is compatible with Nlaunchy, as you are able to launch the CX CAS OS 4.0.3 on a CX CAS hardware.
Which you may consider as pretty useless.

What's broken since version 3.6 is that you can no longer launch the OS on another platform than the one it targets in its header.
3.6 CAS OS cannot be launched on a non-CAS TI-Nspire.
3.6 CX OS cannot be launched on a TI-Nspire CM.
3.6 OS cannot be launched on the last TI-Nspire DVT prototypes.

Due to the way the nLaunchy exploit works, TI OSes cannot be launched out-of-the-box. nLaunchy patches the OS at least to go around a name issue and repair what the exploit broke. In practice, nLaunchy also patches the OSes for other purposes like running ndless when the OS is ready.

However, there is a specific check in OS 4.0 which verifies that it is running on the 'right' hardware. nLaunchy does not remove this check.

I hope it answers your question .

Well, now, nLaunchy remains a bit useless until someone discovers a breach in ≥3.2.x Boot2s

Hi, I have no experience with nLaunchy. I have a few questions. On GitHub, it says

If your current OS is between 3.3 and 4.0, install OS 4.0 and use nsNandMgr. ( http://ti-pla.net/a10080 )

I have nsNandMgr, but how do I get the 3.1.0.16 boot2 with it? And I currently have version 4.0.3.29, this counts as version 4.0 right? Lastly, Can I delete the NLAUNCHED software off of my calculator and install any version of new TI software if I want to?

UPDATE: Oh, well it was misleading when it says you can get CAS 4+ version software on non CAS. Are there any REAL differences between 3.6 let's say, and 4.0?
