Well, there's an Haskell compiler for arm if I recall correctly. So it's pretty easy. :P

Wait.
So the experience coding with the Prime will be like coding with pre-TI-83 calculators?

The OP is kind of misleading, but it's really C. The coding experience would be comparable to the Casio Prizm.

By the way I hacked a little in Lionel's code, I have no idea if it works since I have no HP Prime, but feel free to try it and tell me if it works. Pretty much the same installation instructions as in the OP.

Edit: wait where's the attachment? It says it's there but it's not.

Well, C compiles to some sort of machine code like ASM does and there's no official C compiler dedicated to the Prime, but yeah when ASM is possible on an ARM device, C is automatically possible too.




Also I would try the proof of concept linked in the first post and yours, but I spent $200 with shipping included for that calc and since I often had connectivity problems in the past, I was worried that I could brick my calc or become no longer able to get it detected by my computer. I would rather wait until we have a shell-based example, a way to dual-boot or an OS patch that still provides full official firmware functionalities before taking any risk.

I see, but as they said, you can easily go back in recovery mode and go back to the official OS, but yeah there's still a non-null chance to brick it if you mess up. Probably not worth it considering you spent a lot on it.

Oh ok, but I was more worried about if an OS file accidentally erased the recovery mode code or something, if that's even possible at all.

I'll just quote the HP Museum thread:
Quote from: debrouxl
Quote from: eried
does the firmware utility always recover the calculator to the "upload" mode?
Holding Symb before and after releasing the Reset button should always be able to recover the calculator, indeed. That is, unless one destroyed the area where the contents of BXCBOOT0.BIN are stored, triggering intentional bricking.
So yeah either you failed bad time with putting the elf in the OS upgrade file so BXCBOOT0.BIN corrupted or said elf messed up with said area where the contents of BXCBOOT0.BIN are stored. Either way, you messed up badly in a specific way if you manage to brick your calc. But normally (someone should confirm it), you should be safe.

Ah right, so that's the area we must not touch. Beware, ASM/C coders :P

@Juju if you can use GCC you have asm readily available. You can even inline it in C code if you want, or you can do pure asm programs.

That is true. There is no C without asm, but the opposite is not always true. ARM processors should always support C.

Agreed. Modern ARM is basically built to run Linux and C.
