If your connectivity kit doesn't detect any update for some reasons, you can download it on their FTP folder at "ftp.hp.com/pub/calculators/Prime/".
Make sure to backup any data (such as school programs, your CW contest entry (http://codewalr.us/index.php?topic=432.0) and/or other projects) from your HP Prime emulator and calculators beforehand, just in case.Source: http://www.hpmuseum.org/forum/thread-3823.html
TL;DR, did they released a C/C++ SDK?
Still not I suppose. It's sad. Someone donate one to me already so that I can hack it. :P
Like the Nspire, the Prime is tailored for school and exam testing usage. HP devs will have the duty to close arbitrary native code execution holes in the standard OS, Cyrille de Brébisson was on public record about that. HP will simply not release a native code SDK for the Prime...
However, the Prime remains a far more open calculator than the Nspire is, because as proven by critor and I, we can flash arbitrary OS onto it. So far, I'm the only person who took advantage of that capability, using standard C/C++ tooling targeting the ARM ISA, in a bare-metal, freestanding environment. That's a real shame.
Nobody bested my man-day of work on that PoC (which means both Proof of Concept and Piece of Crap here). I get to criticize my own work as much as I want, and I can safely state that in absolute terms, what I did thoroughly sucks, though in relative terms, it's the only program of its kind on that platform :)
For over a year and a half, we've all known what needs to be done with leveraging the Prime's power for our own purposes. However, nobody does it, due to lack of time and low user base, which raises lack of interest in the platform.
Yeah it's a real shame. I'd love to play around with it. I have some experience with bare metal arm, the soc is heavily documented so it shouldn't be a big issue besides getting the hardware (I don't have that much money).

Yeah it's a shame that not more people are interested in hacking the calc. On the other hand, there are probably some people who think hacking it is useless because of how powerful HP PPL is. Just look at how smooth Mineprime smoothscrolling is.
I personally am not as upset that HP locked the HP Prime down than I was with the TI-Nspire, because they at least did the effort to give us a good alternative. TI took 4 years before finally doing it and while Lua has improved a lot since then, it still has some annoying limitations that can hinder speed considerably.
That's true, but low level languages aren't only a matter of speed. :P Asm can be pretty fun to mess with, even on ARM.
Yeah true. However, seeing how few hardcore ASM coders there are on Z80 calcs compared to BASIC/Axe programmers and how much smaller the HP Prime programming fanbase is compared to TI-z80's, I bet that there are probably like 3 or 4 people who are really interested in hacking the HP Prime and maybe not even one of them have the time to do it.
Hacking would be cool but I don't want HP to lock it down like the NSpire. And \/

To put that is perspective about MinePrime I display two GROBs that are each 1600x800 in size 16 times to do the smooth scrolling. Sadly I tried using a 320x240 GROB but copying to it was too slow :(.
EDIT: To say the truth if there were exploits out I would definitely use them :P
Aah I see. Lua cannot use such GROB IIRC so you have to redraw the map parts shown on the screen frame by frame, one tile by one. But even in HP PPL doing this would be faster than Lua I think. I wish that they made a 400 MHz Nspire CX with 256 MB of Flash.
But isn't HPPPL compiled anyway? and since Lua is interperted you'd HPPPL to run faster anyway
It is. I wish TI went such route.
Having TI use LuaJIT (http://luajit.org/performance_arm.html) would be a great step forward already.
Also it would be nice if their Lua didn't remove many commands (although it's ok I guess if they have to remove some to respect exam regulations), so that people who learn Lua for computer programming have an easier time porting their programs to the calculator. Would LuaJIT automatically do that?

Well, there's no need for exploits on the prime. You can run arbitrary code just by replacing the OS, which the calculator isn't locked against at all unlike the Nspire. I already suggested a preloaded that can load either the OS or custom code, but since I do not own the calc I can't do it myself.
It's a shame that you have quit Prime developement Street, though, since you had the bootloader/rootkit idea. D: I guess it doesn't help that you don't have the calc, but again tr1p1ea has developed Desolate 83+ and several other 83+ games without ever touching one before.
Yeah but he could use the emulator I suppose. There's none for the prime yet.
I developed DovahCalc CSE entirely on an emulator too
I have two Primes actually :). When I got the first in the mail it had a cracked screen so I could only see half of it but I could still use it normally. I could mail it to you but I would have to find a way to get it sent out with my parents not knowing as they don't even know about my account here. That would help if you wanted to get into heavy development :).
Are you not allowed to send stuff? or have accounts on fora? O.O
I'm glad my parents are quite loose on that
How cracked is it ? Just the LCD with the touch panel working fine ? Let me see if I can find a replacement screen. :P
Edit: forget it lol, it's impossible to find spare parts for calculators. So unless I can find another cheap calc to frankenstein them together it's useless.
The touch pannel is just fine you cant even feel the crack so everything works you just can't see half the screen :P.

They don't know I have an account here so it would be weird sending a calculator in the mail to a random person (as they know one of my most prized possessions :P).
Also do you really live in Israel because that might get expensive.
EDIT:
@Cumred_Snektron what is fora?
Its the plural of forum :P (i thought it was the same in English as in Dutch since its a Latin word)
Oh I think it is just forums :P. But yeah they don't even know about my email.
I'm not a horrible child though I follow all the other rules... :-X
Sorry for the double post but this should be noted: Next time you get time look at the DEBUG feature O.O you can actually use it now it looks AWESOME!!!

The emulators were ultra-crap back then, though :P
