Hello
sorry for my bad english im from germany
Me too  yesterday i saw this video
can you help me to get this on my ti nspire cx
i got linux without grapics with linuxloader2 working but i dont know so much about that theme 
The kernel in this video is still the old version (without DTB support, not mainlined), so you'll have to use one of these builds (expanded) and extract one of the xconfig filesystems onto a usb drive. Run "startx" and it should work. if i use linuxloader 2 i can restart the calculator and i have the normal os is it similar with this linux version
thank you for your help 
You can use nlaunch to skip the OS, but as it's a bit more complicated I'd try to get it booting manually first.

For the uart, it might be better to use the Nucleus SDC_* API directly than using the standard library. This doesn't actually solve the issue with ndless' swi handler. I'm currently ill and have no time to debug it, though  Try using SDC_printf() or SDC_Put_String() [formerly called log_rs232]
SDC_Put_String has been tested , SDC_printf untested Untested in which way? Bugs not completely explored or SDC_printf("Hello World!") may not even do anything? The program goes resident after hooking into the Battmon task{That frequently updates the battery icon on the screen} . I've never seen a task which does it's job worse than that... If these syscalls have no disadvantages over the c API, why not replace printf(...) with SDC_printf(...)? And are the addresses (3rd item) for cx cas or cx without cas? Currently I'm using #define fputs(s,f) irq_fputs(s,f)
inline void irq_fputs(char *s, FILE *f)
{
fputs(s, f);
__asm__ volatile("mrs r0, cpsr;"
"bic r0, r0, #0x80;"
"msr cpsr_c, r0;" ::: "r0");
} which works without custom syscalls (and will/should therefore directly work with ndless 3.6).

Except for the places where the webkit/blink engine have bugs with conforming to standards. As a developer, I've run into quite a few instances where Fx supports something properly and everything else balks. Or where Webkit is the only thing that doesn't like it. Exactly, I only code standards-conforming and it never happened that it didn't work in opera. Mostly webkit has issues and firefox works, but sometimes it's both (redrawing issues) and just opera works. Seriously, blink/webkit is becoming the new IE. I <3 Presto

@Vogtinator: i mean so we can run more file extensions!!!!!
ndless.cnf.tns has support for file extensions, there just has to be a program to open the file. i konw this is a dumb question but whats a usb driver interface and what would that do on a nspire 
It would be needed (at least it'd make it easier) to write a driver for communication between calc + PC (via USB) and there are many ways this could be useful. Think of MTP or USB serial. No special driver on the PC needed, just plug in and access the files. Or calc + calc communication (multiplayer games?).

I've been using opera since I got my own laptop at age 10 or something. (Now opera 12.16 cause on linux)
I was curious about speech recognition and googled "speech recognition" and found out opera had it integrated.
Downloaded, worked and instantly opera became my favorite browser.
It's not very good, but far better than firefox, chrome, konqueror and other webkit-based crap if you're a web developer.
Dragonfly is the best tool, the "thing" built into webkit/blink is unusable and even worse than IE's.
And with CSS prefixr and some "mask as firefox" marked sites I didn't came across any page that didn't work.
And if the page doesn't work, it's 99% not conforming to standards...

@ExtendeD im not really sure. mabey more (diffrent) file support.so we can make/run more programs? do u think it will open up new oppertunities???
Huh? What do you mean by "more (different) file support"? A USB driver interface for device mode would be a nice feature, but probably even more work than host mode.

Yes, it'll run on OS 3.6

Jup, each pixel is 4 bits, so half a byte. You can either:
-store the half byte in a separate register
-switch to 8bit mode
-use a separate method for reading and writing pixels given x and y
-use c and don't think about the low level stuff

Maybe nlaunch somehow corrupted your boot2. Do you have access to RS232 (also helpful for log messages)?

Jup, native code execution on an RTOS means unprotected access to the hardware and therefore the whole system.
If they had a "real" OS such as windows ce or linux on it it would be perfectly doable to implement a very secure system.

When I enable interrupts using
__asm__ volatile("mrs r0, cpsr;"
"bic r0, r0, #0x80;"
"msr cpsr_c, r0;" ::: "r0");
and call "printf", "fputs" etc. the 0x80 bit is set again.
Workaround is to clear the bit in the CPSR after the syscall.
SPSR_svc seems to have the correct value in the SWI handler.
I'm using ndless 3.1 r914, is this a bug or did I overlook something important?

That wouldn't make any sense as OS 3.6 is out now. So wait for ndless 3.6 instead

crafti has the fundamental things (chunks, block properties etc.) already built-in, so it shouldn't be too hard to make a game out of it. There are still some problems in nGL, though, the missing z-clipping causes some weird glitches in some situations. When I have some time (or want to procrastinate  ) I'll fix those issues (and remove buggy keypad IRQs again) and implement some block modifying stuff. Should I go the ray-box intersection route or the color coding route?

Hi, have some peanuts:  Luckily they are free here xD On Mac OS X you'll have to install XCode + clang and use XCode with Makefiles or QtCreator if you want something cross-platform.
