Ndless / Re: Ndless 2.0 for TI-Nspire Clickpad/Touchpad
« on: January 05, 2011, 10:23:04 am »
Thank you for completing your post.

Crashes and the unrelated loading loop of elder OSes and Ndless packages seem to be loaded with them, and keymapping may be the least of our worries.

Crashes have allready been reported. I've reported severall of them, with various programs, especially on the TI-Nspire CAS. ExtendeD is working on them.
It's true that crashes are much more frequent with the Ndless 2 build I'm using, than with Ndless 1.7


The elder OSes  reboot loop has nothing to do with Ndless. The elser OSes simply don't support correctly the new Touchpad hardware and the new TouchPad keypads.
As the problem does happen at boot time, we can't interfere with that in any way.
You should ask TI to fix that, but I doubt they will ever...

Which are?...
I don't know of any disturbance which has not allready been reported here.

Did any of you come across the same crashes/freezes as critor and Levak?
critor, do you know which revision of Ndless 2.0 are you using?

I'm testing all pograms with Ndless 1.7 and Ndless 2.0.
The 2.0 revision I'm using currently is 351.

I'm still building binaries with Ndless 1.7 for now.


It might be related (or not) to what Mrakoplaz has reported previously, but I've got something interesting.

mViewer is quite stable with Ndless 1.7, on non-CAS calculators, or even with Ndless 2.0 on non-CAS calculators.
I've got problems with the same binaries with Ndless 2.0 on a CAS ClickPad.
After exiting mViewer, the calculator does freeze or reboot very often (which does not happen on the non-CAS).

The CAS ClickPad did even reboot one time while I was working in the OS, which never happened to me before (no, the RAM was not full).



Both Levak and I have been using TI-Nspire CAS ClickPad for the nDoom tests, which could explain the high freeze/reboot rate.

Cool stuff! ^^ It looks like it has a decent framerate too!
It has 40 fps, but the full speed (of unoverclocked calculator) is around 100 fps.

I also tried the audio+video together, but the audio was almost unusable :-(


Not a problem if we have 2 calculators!
And with 3 calculators, we could also have stereo! :P

Goplat -> It doesn't prove anything, but the TI-Nspire Diagnostic Software 2.00.1183 (the one included in TouchPad Nspire with the new hardware) still contains the NOR flashing/updating strings. The chip has been merged with the ASIC, but seems to be still writeable...
IIRC, the diagnostic software contains a lot of useless stuff such as the SD card test. That NOR flashing exists does not necessarily mean that it's possible. (Correct me if I'm wrong - I'm not really an Nspire guy.)

The SD card test is not useless.
It just doesn't work with you, because you don't have the Nspire SD card reader connected to the dock.

But factories and service centers have it, in order to flash NOR (boot1) and NAND (boot2 + diagnostic + OS).
Remember that diagnostic is run at boot1 level, and that USB support is only available at boot2 level.

Thank you Markoplaz.

Together with Levak, we have tested your game and have experienced some little bugs.

Note it might come from Ndless 2.

- if the WAD file is not in the soft-root directory, after validating the dialog box the calculator does freeze (4 times on 3 different calculators)

- when exiting game with the "esc" key, the calculator does freeze (1 time) or reboot (2 times)


It would be a good idea too to accept the arrow keys together with the numeric keys.
On the ClickPad keypad, we have some alpha keys between the numeric keys, which is "horrible" for an action game.

Finally, it's not easy to recompile existing C libraries (lPNG, libJPEG, zlib, sumatraPDF...) for the TI-Nspire.

You've got to remove most #include lines...
You've got to implement some missing functions...
Some libraries are using very OS-dependant functions (memory manager for exemple) which are implemented only for PC/Mac...

And after changing all this, you're getting something that compiles itself.
But it doesn't prove it is going to work...


For exemple, I managed to compile libJPEG and got... a reboot.

I've identified the problem. A similar problem has allready been reported by Mrakoplaz.

A function is stored as a pointer in a struct during initialisation.
And when that function is used (through the pointer) -> reboot... even if the function does nothing.

Wonderfull!

The screen blur is allmost invisible while moving forward/backward.
It's only visible while turning left/right (which is not your fault).


You've made a great work.


Sincerely (again), you should let the users set the contrast themselves during the game with the "plus" and "minus" keys.
It's very simple: you just have to increase/decrease the value stored at 0x900F0020. Default value is 0x80. I'm using values between 0x60 (full-white) and 0xC0 (full-dark).

Check the free space available after a full reset with each OS in english language (can change but very slightly with another language):ac=voir&id=1922]TNOC[/url])[/i]
Aren't all the languages stored in the OS, no matter what language is used?
Could we use an ndless program to delete those?


The samples are stored in something like 15 different languages in the TNO/TNC archive, which is stored in /phoenix/install/ . That file is vital for the OS as it is used at every boot.

You've got a PC program to delete those before installing the OS: TNOC.
A Ndless program won't be easy to develop, as you'll have to port zlib.
Moreover, if anything goes wrong with the Ndless program, your OS won't boot again (with TNOC, the patched file just won't install -> nothing dangerous).

Ah, it's so great with "good" vertical textures.
Thanks for fixing that.

I'm updating everything.

Yeah true, but PTT is there to not let you open documents other than for the calculator's functionality. This can include forbidding opening documents with CAS/other tools.

There is no way to automatically check an assembly program for its functionalities...
That's what we were talking about.

^^ Don't bother. PTT is there for a reason. You're testing, not playing GBC.

Educational programs can also be made in assembly.
Assembly is not only for games.

The "document format not supported" error is probably caused by a bad file path.

So it isn't worth fixing anything there?


Well... it might be worth for cheating in exams?

Depending upon how it works, you might be able to launch a Ndless program in PTT mode and still have the flashing LED saying that you're not cheating... :P


But we don't want that, of course.

Just for information.


You can try to install Ndless in PTT mode.
You just have to send the files after activating PTT.
They'll be stored in the temporary "Press-to-Test" folder.

Ndless installation seems to behave exactly like in standard mode (busy for severall secs), except that I don't get the lines at the bottom of the screen when the install dialog box is shown.

Trying to open an Ndless program after that just fails (document format not supported).

Trying to install Ndless a 2nd time is triggering a reboot (uninstall, like in standard mode).


Of course, we could have some Ndless program to disable PTT.
But that would be totally useless, as you need another calculator or a computer to install Ndless.
And if you have another calculator or a computer, you can just exit PTT mode by using the menus.
