來把之前的進度先 commit

異動的部分都落在 meta-proscend/conf/distro 資料夾

➜  distro git:(develop) ✗ pwd
/home/jeffrey/M300_git/M300/meta-proscend/conf/distro

異動的摘要如下

➜  distro git:(develop) ✗ git status

Your branch is up-to-date with 'origin/develop'.
Changes not staged for commit:

        include/image_nandflash.inc
        proscend-m300e.conf

no changes added to commit (use "git add" and/or "git commit -a")

目前的 machine configuration 有兩個

m300.conf
m300e.conf

distribution configuration 有三個

proscend-m300.conf
proscend-m300e.conf
planet-m300.conf

利用 proenv.sh 連動 local.conf 有三種方式

source proenv.sh m300 proscend-m300
- machine configuration = meta-proscend/conf/machine/m300.conf
- distribution configuration = meta-proscend/conf/distro/proscend-m300.conf

- machine configuration = meta-proscend/conf/machine/m300e.conf
- distribution configuration = meta-proscend/conf/distro/proscend-m300.conf

distribution files 共用的 file 為 meta-proscend/conf/distro/include/proscend-base.inc

我需要把不屬於共用的部分先從 proscend-base.inc 抽出來

這兩個跟 m300 machine 相關的 distribution configuration file 都需要 include image_nandflash.inc

include conf/distro/include/image_nandflash.inc

conf/distro/include/image_nandflash.inc 內容如下

IMAGE_FSTYPES += "nandflash"
UBOOT_CONFIG = "nand"

這一次的主角 proscend-m300e.conf 內容如下

DISTRO = "proscend-m300e"

EXTRA_USERS_PARAMS = "usermod -P 2wsx#EDC root; \
        useradd -P 2wsx#EDC proscend;"

跟 proscend-m300.conf 的差別只在於

include conf/distro/include/image_emmc.inc

image_emmc.inc 內容如下

UBOOT_CONFIG = "sd"

目前先不考慮 IMAGE_FSTYPES

就先這樣做 commit 吧

    Support emmc design:

    We have 2 machine configurations:
    - m300.conf
    - m300e.conf

    3 distribution configurations:
    - proscend-m300.conf
    - proscend-m300e.conf
    - planet-m300.conf

    Current we have 3 ways to use 'proenv.sh' to initialize the compiling environment:
    - source proenv.sh m300  proscend-m300
    - source proenv.sh m300e proscend-m300e
    - source proenv.sh m300  planet-m300

用正規的方式來修改 u-boot-imx 的 include\configs\mx6ul_14X14_evk.h

加入 #define CONFIG_MX6UL_EVK_EMMC_REWORK

這樣一來 u-boot 便能認得 mmc 了

紀錄一下步驟

bitbake u-boot-imx -c devshell
quilt new add_emmc_rework.patch
quilt add include/configs/mx6ul_14x14_evk.h
修改 include/configs/mx6ul_14x14_evk.h
- 加入 #define CONFIG_MX6UL_EVK_EMMC_REWORK
quilt refresh

用正規的方式來修改 kernel 的 imx6ul-14x14-evk.dts

先用 bitbake linux-imx -c clean 清一下

利用 bitbake linux-imx -c devshell 找到 linux kernel temporary source code

build_small\tmp\work-shared\m300e\kernel-source

建立新的 patch

quilt new imx6ul-14x14-evk.dts.emmc.patch

notify Quilt about the files you plan to edit

quilt add arch/arm/boot/dts/imx6ul-14x14-evk.dts

參考 MX6UL_Development_database_2017.4.21_V7.doc 來作修改

把 patches/imx6ul-14x14-evk.dts.emmc.patch 複製到 meta-proscend\recipes-kernel\linux\files

修改 meta-proscend\recipes-kernel\linux\linux-imx_4.1.15.bbappend

先使用 bitbake linux-imx -c clean 將 linux-imx 作 clean

先使用 bitbake linux-imx -c devshell

會先做 unpack
再做 patch

利用下述命令確認 dts 的修改無誤

make imx_v7_mfg_defconfig
make imx6ul-14x14-evk.dtb

執行 bitbake linux-imx

上 code 囉

試著用 source proenv.sh m300e proscend-m300e

然後用 source bimage.sh 完整的走一次目前的 compile 流程

1625

source bimage.sh 順利的走完了整個 compile 流程

看一下我有什麼可以讓 MfgTool2 利用

build_small\images\u-boot-m300e.imx-sd
build_small\images\zImage-imx6ul-14x14-evk.dtb
build_small\images\zImage
build_small\images\core-image-minimal-m300e.tar.bz2

對應到目前 MfgTool2 的 mfgtools\Profiles\Linux\OS Firmware\files 為

u-boot-imx6ulevk_sd.imx
imx6ul-14x14-evk.dtb
zImage
rootfs_nogpu.tar.bz2

先建一個 mfgtools\Profiles\Linux\OS Firmware\files\v01 來放目前的 mfgtools\Profiles\Linux\OS Firmware\files\*

再建一個 mfgtools\Profiles\Linux\OS Firmware\files\v02 來放 source bimage.sh compile 出來的

u-boot-m300e.imx-sd
zImage-imx6ul-14x14-evk.dtb
zImage
core-image-minimal-m300e.tar.bz2

將 mfgtools\Profiles\Linux\OS Firmware\files\v02\* 複製到 mfgtools\Profiles\Linux\OS Firmware\files*

v02\u-boot-m300e.imx-sd

不過從 emmc 開機發生了問題

從 morris 那邊拿了一片從來都沒燒過的 CPU 板再燒一次

這次從 emmc 開機連 uboot 都開不起來

感覺 ucl2.xml 還要再 review 一下
