mediacom 711i sviluppo custom rom

[merlinolillo]

Il problema del nostro tablet sono i tasti touch. Se non fosse per quelli sarei già in grado di customizzare una rom con kernel ottimizzato. Ma sembra che il driver del touch siano stati compilati all'interno del kernel e non ho la documentazione per poter modificare la configurazione del kernel. Altrimenti bisogna usare il kernel stock e modificare il system, ripachettizandolo. Ma non mi sembra che sia molto diverso come prestazione dalla rom stock. Si può rotizzare, aggiungere qualche ottimizzazione, togliere o mettere pacchetti etc. Tutte cose che si possono tranquillamente già fare montando la stock originale.

Ci sarebbe un modo per ottenere quella documentazione necessaria?

sto cercando, ma niente. Servirebbe sapere a quale modulo del kernel corrispondono i tasti capacitivi.

Se mi dici come posso effettuare la ricerca, ti do una mano volentieri. Non so cos'è un modulo del kernel. Non me ne intendo molto di android tecnico purtroppo

I tasti vengono comandati da uno chipset hardware. Se conoscessi il modello potrei cercare di scoprire a quale modulo del kernel corrisponde.

Intanto ho scoperto che la frequenza viene impostata inizialmente dal kernel a 1080. Ci sono alcuni kernel che la impostano direttamente a 1200. Credo che abbiamo modificato il codice del kernel in questo punto.

#define SUN4I_CPUFREQ_MAX (1008000000) /* config the maximum frequency of sun4i core */
#define SUN4I_CPUFREQ_MIN (60000000) /* config the minimum frequency of sun4i core */
#define SUN4I_FREQTRANS_LATENCY (2000000) /* config the transition latency, based on ns */

Pippo vedi che federico83 ha aperto il tablet facendo varie foto puoi chiedere a lui di postartele nel caso si legga il modello del cipset ;-)

Guarda qui http://www.kikya.com/uploads/711i.jpg ma non c'è nessun chipset secondo me si deve togliere la scheda madre dal tablet e vedere se dietro c'è scritto
Edit:
il chipset e Allwinner A10

lo avevo gia' visto da tempo cmq si puo' sempre settare al max 1,2 ghz

si può alzare anche di più ma andrebbe in malfunzionamento. La frequenza massima di 1.5 credo che sia teorica, in pratica non funzionerebbe.
