Friendly ARM NANOPC-T3 kernel compilation encountered problems

For the rookie level of me, the first to compile the kernel, really difficult, a kernel compiler let me toss for a week, poor my Win7 system, because the installation of Ubuntu has to reload, the final computer data are all formatted. Keep a record of the problems I've encountered.

(1) Install Win7 and Ubuntu Dual system: Installed on the win7 system Ubuntu online tutorials a lot, but from my trial experience, with EASYBCD, hard disk installation method is the simplest, reference URL: http://jingyan.baidu.com/ Article/e4d08ffdace06e0fd2f60d39.html, but before installation, it is best to find a relatively idle disk for compression, the Ubuntu partition on this inside, simple settings/,/boot,/home3 partition can be. Note that it is important to determine which disk the mirror is on, that is, (hd0,0) must not write casually, in order to install convenient can put the mirror on the C disk.

(2) Install GIT, for rookie level of me, can only follow the tutorial step-by-step down, tutorial use git, but I am still installed not git, was stuck. My version is 12.10, then someone suggested that I install 14.04, after installation, apt-get install git can not find the source, only download source installation, reference URL: http://blog.csdn.net/lianshaohua/article /details/50571560, but the installation is not smooth, the middle of a lot of dependent libraries need to be installed, can only bite the bullet one installation, fortunately finally installed. But then know that no need to install git can not, direct download source code decompression, may have been git checkout this command to scare, in fact, do not care about it.

(3) Recompile the kernel, so that its HDMI output resolution of 1080p, according to the friendly tutorial configuration of the kernel, make can, but I uimage replaced by the boot after the reboot, the error

Error:driver ' Nxp_edid ' is already registered, aborting ...
[3.104000] nxp_edid_init:failed to I2c_add_driver ()
[3.108000] hdmi_init_context:failed to Nxp_edid_init ()
[3.116000] register_nxp_hdmi:failed to Hdmi_init_context ()
[3.124000] register_nxp_out:failed to REGISTER_NXP_HDMI ()

Asked the friendly technical support to say that their tutorials are no problem, thought or not in accordance with the tutorial configuration, in device Drivers-->multimedia support-->nexell v4l2 Devices-->nexell Out interface underneath the
Enable out of the HDMI removed *, that is, not to enable, or the tutorial configuration Nexell Graphics [*] HDMI conflict, and indeed changes after the compilation of burning, the success of the output of 1080p.

Because today just remembered to record, the middle encountered many problems can not remember, and later to add it.
