VisionFive - Mender - Yocto

Na rozvoj využívame pobočku Yocto Kirkstone. Predpokladáme, že už máte nainštalované pracovné vývojové prostredie a nastavíme svoje prostredie tak, ako je popísané v VisionFive - Mender - Yocto - časť 1.

Nastavenie servera Mender

Inštalácia servera Mender nie je súčasťou tejto série článkov. Pre naše testovacie prostredie sme nainštalovali server Mender pomocou inštalačného návodu s docker-compose, ako je popísané v časti Inštalácia pomocou Docker Compose.

Klon meta-mender

Prejdite do svojho adresára poky - v mojom prípade poky-kirkstone - a naklonujte úložisko meta-mender. Keďže ešte neexistuje vetva Kirkstone, musíte klonovať vetvu "master-next".

cd poky-kirkstone
git clone -b master-next https://github.com/mendersoftware/meta-mender.git

local.conf a bblayers.conf

Skopírujte bblayers.conf.sample-mender a local.conf.sample-mender z adresára meta-interelectronix-visionfive do adresára conf a premenujte ho na bblayers.conf a local.conf:

cp ../poky-kirkstone/meta-interelectronix-visionfive/conf/bblayers.conf.sample-mender conf/bblayers.conf
cp ../poky-kirkstone/meta-interelectronix-visionfive/conf/local.conf.sample-mender conf/local.conf

V súbore bblayers.conf musíte upraviť cestu k adresáru poky-kirkstone. Tiež odstráňte riadok '/workdir/poky-kirkstone/meta-interelectronix ' - je potrebný iba pre naše prispôsobenie psplash.

Dôležité nastavenia v local.conf sú:

# mender settings
# The name of the disk image and Artifact that will be built.
# This is what the device will report that it is running, and different updates must have different names
# because Mender will skip installation of an Artifact if it is already installed.
MENDER_ARTIFACT_NAME = "release-1"

INHERIT += "mender-full"

# The version of Mender to build. This needs to match an existing recipe in the meta-mender repository.
#
# Given your Yocto Project version, see which versions of Mender you can currently build here:
# https://docs.mender.io/overview/compatibility#mender-client-and-yocto-project-version
#
# Given a Mender client version, see the corresponding version of the mender-artifact utility:
# https://docs.mender.io/overview/compatibility#mender-clientserver-and-artifact-format
#
# By default this will select the latest version of the tools that is backwards compatible with the
# given Yocto branch.
# If you need an earlier version, or a later version even though it may not be backwards compatible,
# please uncomment the following and set to the required version. If you want to use the bleeding
# edge version, specify "master-git%", but keep in mind that these versions may not be stable:
#
# PREFERRED_VERSION_mender-client = "3.3.0"
# PREFERRED_VERSION_mender-artifact = "3.8.0"
# PREFERRED_VERSION_mender-artifact-native = "3.8.0"
# PREFERRED_VERSION_mender-connect = "2.0.1"

# The following settings to enable systemd are needed for all Yocto
# releases sumo and older.  Newer releases have these settings conditionally
# based on the MENDER_FEATURES settings and the inherit of mender-full above.
DISTRO_FEATURES:append = " systemd"

#MENDER_STORAGE_TOTAL_SIZE_MB = "29476"
#MENDER_STORAGE_TOTAL_SIZE_MB = "14738"

Prispôsobte si meta-starfive-bsp

Mali by ste vytvoriť vetvu meta-starfive-bsp na pridanie nastavení potrebných pre nastavenie Mender.

Prispôsobenia sú potrebné v:

• conf/machine/starfive-visionfive-jh7100.conf: Odstráňte alebo komentujte tieto dva riadky

UBOOT_ENV ?= "uEnv"
UBOOT_ENV_SUFFIX = "txt"

• recipes-bsp/bootfiles/files/uEnv.txt: Nahraďte nasledujúci riadok tak, aby zahŕňal premenné Mender počas zavádzania

bootcmd=load mmc 0:1 ${kernel_addr_r} @IMAGETYPE@; load mmc 0:1 ${fdt_addr_r} jh7100-starfive-visionfive-v1.dtb; setenv bootargs 'root=${mender_kernel_root} rw rootfstype=ext4 rootwait earlycon console=ttyS0,115200n8'; booti ${kernel_addr_r} - ${fdt_addr_r}

• recipes-bsp/u-boot/u-boot-visionfive_v2022.03.bb: Pridajte nasledujúce riadky, aby ste povedali meta-menderovi, že sa používa vlastný u-boot

require recipes-bsp/u-boot/u-boot-mender.inc

PROVIDES += "u-boot"
RPROVIDES_${PN} += "u-boot"

BOOT_FILES:append = " uEnv.txt"

Recepty v meta-interelectronix-visionfive

Niektoré nastavenia a premenné je potrebné nastaviť vo vlastnej meta-vrstve, ako to robíme v meta-interelectronix-visionfive.

• recipes-mender/mender-client/mender-client_%.bbappend: Pridajte adresu URL servera Mender

MENDER_SERVER_URL = "https://mender.interelectronix.com"

• recipes-bsp/u-boot/u-boot-visionfive_%.bbappend: Pridajte nasledujúce riadky

MENDER_UBOOT_AUTO_CONFIGURE = "1"
BOOTENV_SIZE = "0x20000"

• recipes-bsp/u-boot-env/*: Pridajte tento recept zo stiahnutého súboru zip. Obsahuje dva súbory uEnv, ktoré sa používajú v koreňovom súborovom systéme. uEnv_visionfive.txt sa používa v rootfoch, pri bootovaní z oddielu A a uEnv_visionfive3.txt sa používa pri bootovaní z oddielu B.

• recepty-jadro/obrázky/vízia-päť-obrázok-mender.bb: Vezmite tento recept na obrázok alebo pridajte "u-boot-env" do svojho receptu na obrázok

  IMAGE_INSTALL:append = " v4l-utils u-boot-env"
