從上禮拜三開始一連 五天 的陪產假

一早 ariel 告知 M300 新版子 來囉

CTCU: -40 ~ 85 C task 優先處理

ospf 要先停工

0925

先幫忙準備 09-25 V1.58 的 mfgtool 版本

CTC: -40 ~ 85 C 開工

先從之前 aaron 幫忙準備的 wiki - Multi kernel uboot 出發

我們目前都是在 M300 source code 根目錄下執行 source proenv.sh

build@2f192722794e:/var/m300$ source proenv.sh

Welcome to Freescale Community BSP

The Yocto Project has extensive documentation about OE including a
reference manual which can be found at:
    http://yoctoproject.org/documentation

For more information about OpenEmbedded see their website:
    http://www.openembedded.org/

You can now run 'bitbake <target>'

Common targets are:
    core-image-minimal
    meta-toolchain
    meta-toolchain-sdk
    adt-installer
    meta-ide-support

Your configuration files at build_small have not been touched.
build@2f192722794e:/var/m300/build_small$

這會連動到 build_small/conf/local.conf

build@2f192722794e:/var/m300/build_small$ cat conf/local.conf
MACHINE ??= 'm300'
DISTRO ?= 'proscend-m300'

注意到 MACHINE

Specifies the target device for which the image is built. You define MACHINE in the local.conf file found in the Build Directory. By default, MACHINE is set to "qemux86", which is an x86-based architecture machine to be emulated using QEMU:

MACHINE ?= "qemux86"

The variable corresponds to a machine configuration file of the same name, through which machine-specific configurations are set. Thus, when MACHINE is set to "qemux86" there exists the corresponding qemux86.conf machine configuration file, which can be found in the Source Directory in meta/conf/machine.

因為 MACHINE ??= 'm300'

所以我們會知道有一個 m300.conf machine configuration file

meta-proscend/conf/machine/m300.conf

UBOOT_CONFIG[mfgtool] = "mx6ul_14x14_evk_config"

1310

再注意到 build_small/conf/local.conf 的 DISTRO

MACHINE ??= 'm300'
DISTRO ?= 'proscend-m300'
...

DISTRO

The short name of the distribution. This variable corresponds to a distribution configuration file whose root name is the same as the variable's argument and whose filename extension is .conf. For example, the distribution configuration file for the Poky distribution is named poky.conf and resides in the meta-poky/conf/distro directory of the Source Directory.

Within that poky.conf file, the DISTRO variable is set as follows:

DISTRO = "poky"

Distribution configuration files are located in a conf/distro directory within the Metadata that contains the distribution configuration. The value for DISTRO must not contain spaces, and is typically all lower-case.

由 DISTRO ?= 'proscend-m300' 我們可知

meta-proscend/conf/distro/proscend-m300.conf

include conf/distro/include/proscend-base.inc

DISTRO = "proscend-m300"

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

再看到 meta-proscend/conf/distro/include/proscend-base.inc

...
ACCEPT_FSL_EULA = ""

UBOOT_CONFIG = "nand"

meta-proscend/conf/distro/proscend-m300.conf 的 UBOOT_CONFIG = "nand"
再加上
meta-proscend/conf/machine/m300.conf 定義的 UBOOT_CONFIG[nand] = "mx6ul_14x14_evk_nand_config,ubifs"

UBOOT_CONFIG

Configures the UBOOT_MACHINE and can also define IMAGE_FSTYPES for individual cases.

Following is an example from the meta-fsl-arm layer.

UBOOT_CONFIG ??= "sd"
UBOOT_CONFIG[sd] = "mx6qsabreauto_config,sdcard"
UBOOT_CONFIG[eimnor] = "mx6qsabreauto_eimnor_config"
UBOOT_CONFIG[nand] = "mx6qsabreauto_nand_config,ubifs"
UBOOT_CONFIG[spinor] = "mx6qsabreauto_spinor_config"

In this example, "sd" is selected as the configuration of the possible four for the UBOOT_MACHINE. The "sd" configuration defines "mx6qsabreauto_config" as the value for UBOOT_MACHINE, while the "sdcard" specifies the IMAGE_FSTYPES to use for the U-boot image.

先把上禮拜為了 ospf 做的一些些東西先備份一下

1555

aaron 的 Multi kernel uboot 提到

Use the proenv.sh to switch the target machine.

  • Switch to m300: source proenv.sh or source proenv.sh m300
  • Switch to m300e: source proenv.sh m300e

直接試試看

build@2f192722794e:/var/m300$ source proenv.sh m300e

就只有 MACHINE ??= 'm300e' 不一樣

看到 m300e.conf 這個 machine configuration file

meta-proscend/conf/machine/m300e.conf

UBOOT_CONFIG[qspi1] = "mx6ul_14x14_evk_qspi1_config"
UBOOT_CONFIG[mfgtool] = "mx6ul_14x14_evk_config"

發現跟 meta-proscend/conf/machine/m300.conf 一模一樣

先試著解析 meta-proscend/conf/machine/m300.conf 內容

參考 commit - Use bitbake image type to generate M300 firmware

m300.conf 的以下內容都時當時的 commit 產生的

NANDFLASH_ROOTFS ?= "${DEPLOY_DIR_IMAGE}/${IMAGE_LINK_NAME}.tar.bz2"

NANDFLASH_ROOTFS_NAME = "rootfs.tar.bz2"

IMAGE_CLASSES += "image_types_proscend"

看到 IMAGE_CLASSES

A list of classes that all images should inherit. You typically use this variable to specify the list of classes that register the different types of images the OpenEmbedded build system creates.

The default value for IMAGE_CLASSES is image_types. You can set this variable in your local.conf or in a distribution configuration file.

For more information, see meta/classes/image_types.bbclass in the Source Directory.

1625

由 IMAGE_CLASSES += "image_types_proscend" 可以追到 meta-proscend/classes/image_types_proscend.bbclass

aaron 表示這是參考 source/meta-fsl-arm/classes/image_types_fsl.bbclass 做修改的

直接看 meta-proscend/classes/image_types_proscend.bbclass
