VisionFive - Mender - Yocto

Vi bruger Yocto Kirkstone-afdelingen til udvikling. Vi antager, at du allerede har et fungerende udviklingsmiljø installeret og indstillet dit miljø som beskrevet i VisionFive - Mender - Yocto - del 1.#### Opsætning af Mender-server

Installationen af Mender-serveren er ikke del af denne artikelserie. For vores testmiljø, installerede vi Mender-serveren ved hjælp af installationens tutorial med docker-komponering som beskrevet i 'Installation with Docker Compose'.

Før du fortsætter, skal du være i stand til at logge ind på Mender-serveren uden at få nogen fejlmeddelelser.

Klon meta-mender

Gå til din poky-mappe - i mit tilfælde poky-kirkstone - og klon meta-mender-arkivet. Da der endnu ikke er en Kirkstone-afdeling, er du nødt til at klone "master-next "-afdelingen.

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

local.conf og bblayers.conf

Kopier bblayers.conf.sample-mender og local.conf.sample-mender fra meta-interelectronix-visionfive mappen til conf mappen og omdøb den til bblayers.conf og 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

I filen bblayers.conf skal du justere stien til din poky-kirkstone mappe. Slet også linjen '/workdir/poky-kirkstone/meta-interelectronix' - det er kun nødvendigt for vores psplash-tilpasning.

De vigtige indstillinger i local.conf er:

# 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"
VIRTUAL-RUNTIME:init_manager = "systemd"
DISTRO_FEATURES_BACKFILL_CONSIDERED = "sysvinit"
VIRTUAL-RUNTIME_initscripts = ""

ARTIFACTIMG_FSTYPE = "ext4"

# Example: Memory card storage
MENDER_STORAGE_DEVICE = "/dev/mmcblk0"
# Example: Memory card with 2GiB of storage.
#MENDER_STORAGE_TOTAL_SIZE_MB = "29476"
#MENDER_STORAGE_TOTAL_SIZE_MB = "14738"

Tilpas meta-starfive-bsp

Du bør oprette en afdeling af meta-starfive-bsp for at tilføje de nødvendige indstillinger for Mender opsætningen.

Tilpasninger er nødvendige i:

• conf/machine/starfive-visionfive-jh7100.conf: Fjern eller kommenter disse to linjer

UBOOT_ENV ?= "uEnv"
UBOOT_ENV_SUFFIX = "txt"

• recies-bsp/bootfiles/files/uEnv.txt: Erstat følgende linje for at inkludere Mender-variabler under opstart

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: Tilføj følgende linjer for at fortælle meta-mender, at der anvendes en brugerdefineret u-boot

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

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

BOOT_FILES:append = " uEnv.txt"

Opskrifter i meta-interelectronix-visionfive

Nogle indstillinger og variabler skal indstilles i brugerdefinerede metalag, som vi gør i meta-interelectronix-visionfive.

• opskrifter-mender/mender-client/mender-client_%.bbappend: Tilføj URL'en til Mender-serveren

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

• recipes-bsp/u-boot/u-boot-visionfive_%.bbappend: Tilføj følgende linjer

MENDER_UBOOT_AUTO_CONFIGURE = "1"
BOOTENV_SIZE = "0x20000"

• recipes-bsp/u-boot-env/*: Tilføj denne opskrift fra den downloadede zip-fil. Den indeholder to uEnv-filer, som bruges i rodfilsystemet. uEnv_visionfive.txt bruges i rootfs, når du starter fra partition A og uEnv_visionfive3.txt bruges når du starter fra partition B.

• recipes-core/images/vision-five-image-mender.bb: Tag denne billedopskrift, eller tilføj 'u-boot-env' til din billedopskrift

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

Se hvordan du opsætter u-boot til Mender iVisionFive - Mender - Yocto - del 3.
