Third-party firmware PoC...

[Lionel Debroux]

After recently buying a Prime, I've now spent several hours making my own armfir.elf. The result is attached.
The code fills one third of the screen with red, one third with green, and the last third with blue (with some glitches), then enters an infinite loop. Yeah, this PoC sucks, I know - it sucks just as much as my Nspire DummyOS did, more than three years ago.

Usage: copy the armfir.elf file into APPSDISK.DAT. Firmware transfer, enter recovery mode by pressing the Reset button in the hole on the back, pressing the Symb key, releasing the Reset button, and holding Symb until the Recovery mode screen appears. Then, use usbtool (Windows only).

As usual: works for me, but use at your own risk

Good night.

c'est parce que je me connecte en Angleterre, ou le post est uniquement en anglais?

(Post uniquement en anglais pour le moment, oui (edit : cf news de critor en FR+EN ))

Bravo en tout cas
PoC qui ne fait rien d'utile, mais, pas grave : c'est le fait d'avoir réussi qui est remarquable

Je ne comprends pas, qu'est-ce que c'est que le fichier APPSDISK.DAT?

APPSDISK.DAT contient le filesystem qui contient notamment l'OS. Voir https://tiplanet.org/hpwiki/index.php?t ... ware_files
