最近調飛思卡爾iMx6Q的硬體編解碼,需要找sdk參考.故此根據nxp官方手冊,下載與安裝sdk包環境

因為很多關鍵網址被TG檣了.所以花了九牛二虎之力才down下了sdk.

故此筆記如下:

這是飛思卡爾官方的安裝教程.我在其中做出備註.

Freescale's Community Yocto BSP
===============================

To get the BSP you need to have `repo` installed and use it as:

Install the `repo` utility:

下載repo 
$: mkdir ~/bin
$: curl 
 
https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
$: chmod a+x ~/bin/repo
注:這一步最大的問題就是google被封了,下載不下來,超時,要別處搞個repo下來.我的方法是

使用repo 抓下來BSP的原始碼

Download the BSP source:

$: PATH=${PATH}:~/bin
$: mkdir fsl-community-bsp
$: cd fsl-community-bsp
$: repo init -u 
 
https://github.com/Freescale/fsl-community-bsp-platform -b dylan
$: repo sync
注:這一步最大的問題是googlesource被牆,提示如下:

fatal: Cannot get https://gerrit.googlesource.com/git-repo/clone.bundle
fatal: error [Errno 110] Connection timed out
fatal: cloning the git-repo repository failed, will remove '.repo/repo' 

我的做法是: 使用--repo-url=https://gerrit-google.tuna.tsinghua.edu.cn/git-repo引數代理下載.

$repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b master --repo-url=https://gerrit-google.tuna.tsinghua.edu.cn/git-repo

編譯原始碼
Once this has complete, you will have all you need. To start a build, do:

$: . ./setup-environment build
$: bitbake core-image-minimal

You can use any directory to host your build.

The source code will be checked out at fsl-community-bsp/sources.

兩個問題:

1,按照source ./setup-environment build會提示:

	ERROR: You must set DISTRO when creating a new build directory.

	ERROR: You must set MACHINE when creating a new build directory.

所以實際要使用命令如下:

	MACHINE=imx6qsabresd DISTRO=fslc-framebuffer source setup-environment build

2,python3版本問題.因為bitbake需要python3支援,然後ubuntu預設的python使用的是python2.7,python3的版本預設使用python3.2

        提示如下:BitBake requires Python 3.4.0 or later as 'python3'

需要安裝python3.4或者更高版本.apt-get install python3.5

ubuntu 預設倉庫是沒有python3.5的,故此使用

$sudo add-apt-repository ppa:fkrull/deadsnakes

$sudo apt-get update

$sudo apt-get install python3.5

安裝之後將/usr/bin/python3 連結指向/usr/bin/python3.5

$sudo ln -sb /usr/bin/python3.5 /usr/bin/python3

$ls /usr/bin/python3 -l

	lrwxrwxrwx 1 root root 18  9月 14 09:53 /usr/bin/python3 -> /usr/bin/python3.5

bitbake使用:

You can now run 'bitbake <target>'
Common targets are:
    core-image-minimal
    meta-toolchain
    meta-toolchain-sdk
    adt-installer
    meta-ide-support

bitbake提示如下:

Please install the following missing utilities: diffstat,chrpath

解決方法:

sudo apt-get install diffstat

sudo apt-get install chrpath

bitbake提示如下:

Your version of git is older than 1.8.3.1 and has bugs which will break builds. Please install a newer version of git.

吐槽:連庫都嫌我老了,嗚嗚,放開我,我要去狗帶.現在已經有庫開始找曾經的ubuntu12.4的麻煩了

提交包到倉庫--不是大神請跳過.
Contributing
------------

To contribute to this layer you should the patches for review to the
mailing list.

Mailing list:

    https://lists.yoctoproject.org/listinfo/meta-freescale

Source code:
    
    https://github.com/Freescale/fsl-community-bsp-platform

When creating patches, please use something like:

git format-patch -s --subject-prefix='fsl-community-bsp-platform][PATCH' origin

When sending patches, please use something like:

git send-email --to [email protected] <generated patch>

Using Development and Testing Branches
--------------------------------------

Replace the 'repo init' command above with one of the following:

master: for developers

$: repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b master
 
master-next: for intrepid developers and testers

Patches are typically merged into master-next and then are merged into 
master after a testing and comment period. It's possible that master-next 
has something you want or need. But it's also possible that using 
master-next will break something that was working before. Use with caution.

$: repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b master-next
