Anche con load/entry adress come da kernel originale non cambia nulla. se volete provare kernel e kimage sono su http://test.ninux.org/~claudyus/alice_agif == 7 febbraio 2011 == OPENWRT is cooming Ok ci siamo, dopo 3 gg di intenso lavoro ecco il primo repository per ikanos: http://test.ninux.org/~claudyus/alice_agif/openwrt/ === Testare il kernel === Per testare il kernel scaricato dal link di sopra si deve taggare per uboot, usando mkimage puoi usare questo comando: {{{ mkimage -A mips -T kernel -C none -a 0x80010000 -e 0x802b7000 -n linux-2.6 -d vmlinuz kimage.cla }}} Il che genera un file, kimage.cla, che è possibile trasferire via tftp sulla scheda come mostrato nell'aggiornamento del 6 febbraio. == 8 febbraio 2011 == Nulla è stato tentato oggi. Avvolte per chiarirsi le idee su di un problema è meglio distaccarsene... {{attachment:08022011349.jpg|alt text|width=200 height=300}} == 10 febbraio 2011 == Il progetto freetz ha un kernel molto interessate alla versione 2.6.19.2 con supporto per adi_fusiv ma non compila er vox160, all'interno del progetto è usato per vox180... Intanto l'ho messo al solito indirizzo, un passo avanti. Ora un passo indietro... parlando con Florian forse è uscito un problema con la ethernet. {{{ Hello Claudio, On Thursday 10 February 2011 10:07:23 Claudio wrote: > Hi all, > someone of you is know or is part of http://freetz.org/ project? > I found a alicegate [1] variant [2] in italy that is based on fusiv > chip, the chip support is not upstream but downloading freetz sdk I > found a patched kernel 2.6.19.2 that can be a start point to develop > this paltform. > > Other boards are based on same chip, in france livebox and in belgium bbox2 > [3] Keep in mind that just like Broadcom BCM63xx, you might be able to get the basic board support in a working state (CPU handling, UART, USB ...) but the DSL remain as blobs, ethernet might as well. Note that you can also find support for the Ikanos Fusiv DSL platform here: http://www.livebox- opensource.com/Products/LiveBox/LiveBox1.2/Thomson/vR7298/linux-2.6.12.tar.bz2 The Ikanos Fusiv platform uses a Lexra CPU, which is a MIPS compatible clone, excep that it lacks support for 4 patented instructions, so a patched toolchain is required to build a working kernel. }}} ethernet driver as blobs?!?!?!? MEGA FAIL E un passo avanti ancora: pog2 dal forum http://forum.zibri.org ha estratto il kernel dalla flash l'ha taggaro e ricaricato in ram e, NOTIZIA, ha scritto qualcosa sulla seriale!
