Differenze per "agif"

Telecom italia agif modem con openwrt

Byte sparsi sull'hack per info contatti @ ninux.org

L'agif ha un soc analog device architettura fusiv v180, il che non è upstream nel kernel ma sul sito di zoobab si è trovato un kernel moddato da cui ho estratto una leggerissima patch di 50MB (http://test.ninux.org/~claudyus/agif/livebox_diff_small.patch) e il cui lavoro di vivisezione è in corso

Praticamente usando la toolchain del livebox2 e compilando il kernel 2.6.15 che in realtà è un 2.6.25-rc5 si ottiene un kernel da 29MB e un po di cavoli

a questo punto si riduce con objbump e si tagga con mkimage

Su uboot ho usato:

setenv bootargs console=ttyS0,57600 rootwait
tftp 80400000 kimage.cla

con questi risultati:

insomma davvero deludente.

Anche con load/entry adress come da kernel originale non cambia nulla.
