Test RS232 TI-Nspire Navigator Access Point

Unread postby critor » 14 Apr 2013, 13:45

Dans une news précédente, nous vous effectuions un test matériel du TI-Nspire Navigator Access Point, le point d'accès permettant d'utiliser les calculatrices TI-Nspire au sein d'un réseau WiFi en classe! :bj:
1171 2375 2376


Nombre de mystères demeuraient sur cet appareil, et nous nous interrogions sur un lecteur de carte mémoire SD/MMC, un 2ème port USB, un port JTAG, le processeur utilisé...



La meilleure façon d'obtenir un maximum de ces détails est d'accéder à la console série de démarrage de l'appareil en question, console dans laquelle il va bien gentiment nous raconter toute sa vie dès la mise sous tension! ;)

Nous pensions justement avoir identifié le port RS232 dans la news précédente, alors branchons un peu ça:
2386


Et bingo, le TI-Nspire Navigator Access Point se met bien soudainement à parler, sans aucune violence! ;)

On y apprend nombre de choses:
  • l'utilisation du loader X-Loader de chez TI
  • loader qui lance à son tour un loader U-Boot comme sur certaines TI-Nspire CAS+
  • l'utilisation d'un processeur ARM
    (ARMv7)
    dans un ASIC OMAP
    (OMAP3)
  • l'utilisation d'une puce Flash NAND ROM de 128Mo comme sur TI-Nspire CX
  • l'utilisation de 64Mo de mémoire RAM comme sur TI-Nspire CX
  • la mention d'une carte mémoire MMC manquante ici sur laquelle U-Boot tente d'abord de démarrer
  • l'utilisation d'une carte mère de développement BeagleBoard
  • l'utilisation d'un OS de type Linux basé sur le Kernel 2.6.37
  • l'utilisation de la version 3.2.0.18 de l'OS
  • l'adresse matérielle MAC: 00:09:37:1F:0E:C0
  • le SSID du réseau WiFi: TI-NAV-N-0009371F0EC0
  • l'utilisation d'un serveur DHCP pour attribuer les adresses IP aux calculatrices
  • et plein d'autres choses qui sont autant d'innombrables pistes d'expériences et de news potentielles... ;)



A bientôt sur

En plus de tout ce que tu as déjà détaillé, on voit également le gadgetfs et la mention "musb_hdrc", c'est à dire de quoi potentiellement exposer l'AP comme un device USB quelconque vis à vis d'un hôte USB (ordinateur, par exemple).
http://cateee.net/lkddb/web-lkddb/USB_MUSB_HDRC.html pour une description plus détaillée de musb_hdrc:
Say Y here if your system has a dual role high speed USB controller based on the Mentor Graphics silicon IP. Then configure options to match your silicon and the board it's being used with, including the USB peripheral role, or the USB host role, or both.

Texas Instruments families using this IP include DaVinci (35x, 644x ...), OMAP 243x, OMAP 3, and TUSB 6010.

Analog Devices parts using this IP include Blackfin BF54x, BF525 and BF527.

If you do not know what this is, please say N.

To compile this driver as a module, choose M here; the module will be called "musb-hdrc".

Il serait intéressant d'essayer de reproduire le hack matériel ainsi que de retrouver le firmware OpenWRT utilisé.. J'en avais trouvé un à une époque mais je me souviens plus où il est >.>
Par ailleurs, on peut voir qu'il y a une ACL. N'y a-t-il vraiment pas moyen de "voir" le réseau? (j'arrive avec mon téléphone android à voir les réseaux cachés grâce à une appli..)
