So I was casually checking the ndless repo, and as of yesterday, a new commit was made including 1.7 syscalls, a new readme talking about installing on 1.7, and just about every file was updated. However, I haven't seen news of the Ndless 1.7 release. Was it released in secret? I don't have time to compile it right now, if you compiled it (and it's the new ndless), please PM me a copy. Thank you.

From what I can tell, it's still an unstable copy. I wouldn't recommend trying it until a release.

It does work - however, it is incompatible with the current release of gbc4nspire.
Do you still need a copy?

Also, you know what's wrong with it that makes it "unstable"?

P.S: There are many minor versions of 1.7. I assume it works with the "newest" 1.7 (the last version before 2.0)?

For me, it worked fine with 1.7.2741.

I would think it would work on all versions of 1.7, though. I think that is like the differences between 2.0.0 and 2.0.1.

I believe the part that makes it "unstable" is the fact that the program loader does not completely work on hardware.

What do you mean by that? We have to connect to the computer at reboot or something?

It means that running programs sometimes crashes the calculator. The cause is currently unknown, and I assume it is the main thing keeping it from release.

Edit:
Also, when looking through the source I saw some pretty important stuff was missing from the CAS version, so I think it won't even install on CAS yet.

Can this be fixed easily ? . . . Neutral

That's what I'm wondering. Rumor is that calc84maniac lost the source code to it in a computer crash. However, the readme says that it's coded in assembly, so it shouldn't be THAT hard to disassemble it and modify, right?

In theory, I could do a diff between the NON-CAS and CAS versions to find where the OS routine addresses are stored in the program. Then I could just change them to be the OS 1.7 addresses.

Indeed, you should do that. It would be terrible if Ndless 1.7 had no end-user programs.

One problem: It looks like Ndless 1.7 doesn't provide any way to get the current program's path (it used to be passed in r9).

Hmm, well, I've just gotten word from ExtendeD that main(argc,argv) support has been added and the program path is in argv[0]. Smile

That would be great! Very Happy

On TI-Bank.fr, more than 80% of people downloading Ndless are also downloading gb4nspire, you know! Neutral

Great! Here's a copy of gbc4nspire.tns I hex-edited to make it work in Ndless 1.7.

Hmm...the attached file crashes on my non-CAS emulator image.
EDIT: Never mind! I didn't install the latest Ndless.

You probably have to have the updated version I mentioned that adds argc/argv support.

Ok, I see why it's unstable now. (Or I didn't compile right). 1/5 of the time, it freezes at the clock. 2/5 of the time it freezes in a black screen after reboot. 1/5 of the time, it works. If anyone wants a copy of compiled svn build 236 (lastest as of now), PM me. (I also have 1.7 compiled BlockDudeNspire)

EDIT: Ok, Nspire EMU loads Ndless 1.7 perfectly every time. I suspect the thing holding up is finding out why it doesn't work on the calculator 100%.

We probably won't be able to do much for this one.

Try to install Ndless while the calculator is connected to a computer.
