跑完囉

裝一下 libncurses5-dev

sudo apt-get install libncurses5-dev

切換至 <build dir>/tmp/work/imx6ulevk-poky-linux-gnueabi/u-boot-imx/2015.04-r0/git/mx6ul_14x14_evk_config

執行 make menuconfig

可以做實驗了

先記錄一下目前 make menuconfig 的樣子

將 config save 在 .config 了
再來呢?
直接在 <build dir>/tmp/work/imx6ulevk-poky-linux-gnueabi/u-boot-imx/2015.04-r0/git/mx6ul_14x14_evk_config make?
或是到 <build dir> 下使用 bitbake?

先試試 <build dir> 下使用 bitbake 好了

看到 Freescale Yocto Project User's Guide 的 5.4 Bitbake options

-c compile -f 的描述為

It is not recommended that the source code under the tmp directory is changed directly, but if it is, the Yocto Project might not rebuild it unless this option is used. Use this option to force a recompile after the image is deployed.

那我現在算不算直接改了 tmp 下的 u-boot-imx 呢?
要不要先在 <build dir>/tmp/work/imx6ulevk-poky-linux-gnueabi/u-boot-imx/2015.04-r0/git/mx6ul_14x14_evk_config make clean?

算了
直接在 <build dir> 下使用 bitbake -c compile -f core-image-minimal

jeffrey@jeffrey-virtual-machine:~/fsl-release-bsp/build_small$ bitbake -c compile -f core-image-minimal
bitbake: command not found

command not found ???

這就奇怪了

找 ariel 聊一下
ariel 表示

第二次以後: MACHINE=imx6ulevk source setup-environment build_small bitbake core-image-minimal

這裡的 MACHINE=imx6ulevk source setup-environment build_small 一定要做

jeffrey@jeffrey-virtual-machine:~/fsl-release-bsp$ MACHINE=imx6ulevk source setup-environment build_small

也是一下就做完了... 奇怪

看到 <build dir>/tmp/deploy/images/imx6ulevk 根本都是之前的時間

看來有需要研究一下 bitbake 的用法了

1310

中午拿便當的時候跟 ariel 聊了一下目前的狀況

ariel 很快的用 mail 告知如何針對 U-BOOT來做 clean 及 build 的動作

bitbake -c clean u-boot
bitbake u-boot

雖然之前已經直接在 <build dir>/tmp/work/imx6ulevk-poky-linux-gnueabi/u-boot-imx/2015.04-r0/git/mx6ul_14x14_evk_config
做了 make clean

不管了

看不出來有在 build u-boot
看一下 image

哈哈
u-boot-sd-2015.04-r0.imx 有重 build 了
大小是 363520
早上看的也是 363520

好消息是知道怎麼 rebuild u-boot 了
壞消息是大小都沒變

1320

反正是做實驗
從 make menuconfig 再刪幾個掉試試

竟然發現 <build dir>/tmp/work/imx6ulevk-poky-linux-gnueabi/u-boot-imx/2015.04-r0/git 下東西都不見了

1330

關掉原本的 terminal 再重新開一個
然後重做一次下述步驟

MACHINE=imx6ulevk source setup-environment build_small
bitbake core-image-minimal

這要等一下

ariel 表示她跟我做了相同的動作不過她的 u-boot 目錄都還在
我唯一多做的動作就是直接在 <build dir>/tmp/work/imx6ulevk-poky-linux-gnueabi/u-boot-imx/2015.04-r0/git/mx6ul_14x14_evk_config 做了 make clean

最糟就重作囉

不過先在 window 上裝 win-sshfs
這可以透過 SSH 掛載遠端 Linux 伺服器上的硬碟

這樣就不用複製想看的東西到 vmware 的 share folder 來了

window 10 裝不起來... 算了

再看一下 bitbake 的 manual 看看有沒有甚麼方式讓我不用重頭來過

1455

猛一看 manual 還真不直覺阿...
先重作好了
因為我現階段的任務是縮小 U-BOOT image size 阿

mkdir fsl-release-bsp
cd fsl-release-bsp
repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-4.1.15-1.0.0_ga
repo sync

MACHINE=imx6ulevk source fsl-setup-release.sh -b build_small
bitbake core-image-minimal

等吧

1615

ariel 請我看一下 Yocto 的 manual 關於 create partitioned image 的部分

這裡出現一個叫 wic 的 tool

The wic command generates partitioned images from existing OpenEmbedded build artifacts

existing OpenEmbedded build artifacts ?

一堆名詞... 我先看一下 3.4. Yocto Project Terms

1750

剛剛處長跟我聊了一下上半年的考績
不高也不低
80 吧

說我熱情不足
沒有端作品出來

還真的被老婆說中了

看來我這個特質要調整一下

1755

wic 這個 tool 是調整 image 的配置用的
U-BOOT image 太大想縮小的話
wic 幫不上忙
