I started to write a post to explain my personal opinion, but the post that you quoted (I have deleted it to make sure we do not have some stupid discussion here) pretty much sums it up already, so there is probably no need for it.. I just want to clarify that I am in no way "trying to destroy Omnimaga", because Omnimaga itself is a pretty awesome community  So... Sorry for being rude to new members, but seeing something like this instantly pisses me off (just like my post pissed you off so you sent me that PM)

Hi, since I recently had my Omnimaga 2-year anniversary, I thought I should finally introduce myself My name is Julian, I am 17 years old and I live in Germany, near Hamburg. I am in the 12th grade of a grammar school with focus on information technology. The only calculator I own is an Nspire Classic Touchpad, and the reason why I signed up here 2 years ago was that I wanted to play GB games on it ( this is my first post, when I failed to compile Ndless  ) eventually this got me into Nspire C programming and I worked on some projects since then  Also, I have some basic knowledge in other programming languages like PHP/JS/Python/C++. Other things I do in my free time are playing the piano, badminton, gaming, going to LAN parties...  Till now, I enjoyed being here and I hope I'll be here for some more years

Did you delete the OS first? You have to send nLaunch when the boot2 says you have no OS installed.

It looks like something in your Makefile is wrong. Try adding -DPRIZM to the gcc flags or have a look at one of the demo Makefiles. If that doesn't solve the problem you'll have to ask Juju, he maintains the Prizm stuff

Could you post the complete build log?

Wir mussten den TR selber kaufen, nur wer ALG bekommt, bekommt einen von der Schule soweit ich weiß.

Hier auf dem technischen Gymnasium haben wir die unglaubliche Auswahl zwischen Englisch/Deutsch als P3 (Leistungskurs) und Physik/Betriebs- und Volkswirtschaft als P4 (Grundkurs schriftlich) oder P5 (Grundkurs mündlich) und der Nspire Classic Non-CAS ist fest vorgeschrieben.

Use nio_gets or nio_fgets and pass the string to atoi

Link removed in 3.. 2.. 1.. It's nice that someone else found this security hole as well  This just shows how bad the PTT mode is

AFAIK, USB file transfers aren't working anymore after using RootDoc (I think I read that somewhere) But you can reboot and hold ESC so that RootDoc isn't launched and then transfer the exit PTT file. Edit: Nope, linuxloader can't find the kernel image. At least not if I load it with "kernel linux/zImage.tns", maybe the path is different. Try /documents/linux/zImage.tns instead (I guess linuxloader2 searches in the current directory, which is /exammode/usr while in PTT mode instead of /documents) btw, I'm pretty sure that you can't change the LED in PTT either, I've done some tests a while ago EDIT: Oh well, you ninja'd me with your edit

I think the LED has a Lock register similar to the watchdog.
The OS seems to write 0x1ACCE551 to 0x90110C00 before accessing LED registers, but I've tried that and it doesn't work.

Oh well, my explanation was a bit wrong. I assumed he loads the kernel to 0x1000000 (that's what OSLauncher does), which would be the SDRAM starting address (and the place where the stock OS lies, so OSLauncher has to take care not to use any functions of it, furthermore interrupts are disabled during the process, so we can't use syscalls at all, not even ndless functions), but after a quick look at the source he just mallocs as much memory as possible (with stock OS functions) and loads kernel + ramdisk into it (with stock OS functions) and then passes control to the kernel. So there's no need to provide own functions, he can use syscalls the whole time because he isn't overwriting any functions of the OS. But yeah, maybe tangrs can explain this better (and correct me if I'm wrong)

Basically the same way as OSLauncher: while overwriting the OS, you have to make sure not to rely on any OS code, so your loader has to deliver all the functions it needs (in the case of OSLauncher, e.g. zlib for decompressing the OS, or GCC's builtin memory functions).
After removing all traces of the previous OS (things like clearing cache), you can pass control to the new OS.
