[14:33] <lilwiz> Anyone know if HP Slatebook can be turned into an Ubuntu laptop? (It comes with Android on eMMC, Tegra 4 ARM processor)
[14:36] <ogra_> if the bootloader and kernel are open you surely can hack that up ... but likely only with framebuffer driver (no acceleration at all)
[14:36] <lilwiz> Ouch
[14:36] <lilwiz> Alright, it was worth an ask :)
[16:40] <bama_> Guys ,I m porting ubuntu arm64 14.04 into an android tv box, running kernel 3.10.x ,can you tell me how can I get a correct initramfs?
[16:40] <infinity> ogra_, lilwiz: It might work with nouveau.  Newer Tegras are meant to.
[16:41] <bama_> anyone interesting with RK3368 8cores Aarch64
[16:43] <bama_> :join #ubuntu-arm64
[16:44] <infinity> bama_: Using random Android kernel builds isn't really in scope for an Ubuntu channel, to be fair.
[16:44] <ogra_> whats #ubuntu-arm64 ?
[16:45] <bama_> i type a wrong command in irc
[16:45] <ogra_> still that shouldnt exist
[16:46] <ogra_> this channel here is good enough for 32 and 64 bit together :)
[16:46] <bama_> thanks
[16:46] <bama_> is there any strong relationship between kernel and initramfs?
[16:48] <ogra_> depends on your kernel config
[16:49] <infinity> bama_: If you need an initramfs at all, then yes, there's a strong relationship, as the initramfs contains kernel modules.
[16:49] <infinity> bama_: But if all your storage drivers are built into the kernel (which is common with Android kernels), you don't need an initramfs at all.
[16:49] <infinity> You just need to boot with "root=/dev/whatever" and watch the magic.
[16:49] <ogra_> if everything your system needs to boot the rootfs (all systemd options, uboot, filesystems etc) is compiled in... the initrd isnt that important ... if any of your drivers needed to get to rootfs is a module, you need an initrd though
[16:49] <ogra_> s/uboot/udev/
 thanks, im trying
 mkbootimg need a ramdisk argument
[16:56] <bama_> can i create an empty ramfs?
[17:01] <bama_> http://pastebin.ubuntu.com/14030060/
[17:01] <bama_> yes, with out initramfs , system bootup
[17:01] <bama_> but how to modify ubuntu-core-14.04-core-arm64.tar.gz  to fit my board?
 how to modify ubuntu-core-14.04-core-arm64.tar.gz  to fit my board? Such as my serial is ttyS0, which file need to modify, any wiki?
[17:10] <bama_> i copied a tty1.conf to ttyS0.conf ,it works! but how can i sure other point is configured?
[17:13] <bama_> whats the passwd of ubuntu-core-14.04-core-arm64
[17:14] <infinity> bama_: No much else to configure except for network and a user.
[17:14] <bama_> shold i chroot into the target partition and change passwd?
[17:15] <bama_> whats the default root passwd of ubuntu-core-14.04-core-arm64.tar.gz
[17:21] <bama_> chroot and change passwd ok!
[17:24] <bama_> infinity:thanks!
[17:44] <bama_> https://wiki.ubuntu.com/ARM/RootfsFromScratch hereis the officical site about rootfs from scrath ,and the page let user to build rootfs with RootStock
[17:45] <bama_> but the RootStock page said: Note that RootStock has been deprecated and is no longer maintained
[17:45] <bama_> if i want create a rootfs from scrath , which tool is insdead of RootStock
[18:20] <bama_> how can i get Uart serial working in ubuntu-15.10-core-arm64
[18:24] <bama_> i used console=ttyS0,115200 in command line
