Landa Ikhodi Yomthombo ye-MaaXBoard 8ULP
Ukulanda ikhodi yomthombo ye-MaaXBoard 8ULP, fanisa indawo yokugcina ku-Github:

$ cd ~/imx-yocto-bsp/sources
$ git clone https://github.com/Avnet/meta-maaxboard.git -b mickledore meta-maaxboard

Yakha

Hlela ukucushwa kwesakhiwo
Uma ufuna ukwakha ifolda yokwakha entsha noma usethe ukucushwa okokuqala ngqa, sebenzisa umyalo:

$ cd ~/imx-yocto-bsp
$ MACHINE=maaxboard-8ulp imithombo yomthombo/meta-maaxboard/tools/maaxboard-setup.sh -b
maaxboard-8ulp/build

Uma ufuna ukwakha kufolda yokwakha ekhona, sebenzisa umyalo olandelayo:

$ cd ~/imx-yocto-bsp
$ imithombo yomthombo/poky/oe-init-build-env maaxboard-8ulp/build

Yakha
Yenza umyalo olandelayo ukuze wakhe isithombe sase-Weston Wayland:

$ bitbake avnet-isithombe-full

Ngemuva kokuthi ukwakhiwa kuqedwe ngempumelelo, okukhiphayo files afakwe ku: ~/imx-yocto-bsp/maaxboard-8ulp/build/tmp/deploy/images/maaxboard-8ulp/

imx-boot-tagged	Isithombe se-Bootloader

Isahluko 2 Ukwakhiwa Okuzimele kwe-u-Boot neKernel

Lesi sahluko sichaza indlela yokwakha i-U-boot ne-Kernel usebenzisa i-SDK noma i-ARM GCC endaweni ezimele.

Iketanga lamathuluzi lokuhlanganisa
Iketango lamathuluzi lokuhlanganisa elisetshenziswayo, kungaba yi-ARM GCC noma i-Yocto SDK.

I-ARM GCC
Landa uchungechunge lwamathuluzi we-A-profile ukwakheka kwengalo Unjiniyela wekhasi le-GNU-A Lokulanda. Kunconywa ukusebenzisa inguqulo engu-10.3 kulokhu kukhishwa. Ungalanda i-“gcc-arm-10.3-2021.07-x86_64-aarch64-none-linux-gnu.tar.xz “, bese ucindezela file ohlwini lwemibhalo lendawo.

$ mkdir ~/toolchain
$ tar -xJf gcc-arm-10.3-2021.07-x86_64-aarch64-none-linux-gnu.tar.xz -C ~/toolchain

Yenza umyalo olandelayo ukuze uhlole ukuthi i-toolchain ingasebenza ngokuqondile.

$ cd toolchain/gcc-arm-10.3-2021.07-x86_64-aarch64-none-linux-gnu/bin/
$ ./aarch64-none-linux-gnu-gcc -v

Ukuze uhlanganise iphrojekthi nge-ARM GCC, qala usethe indawo ezungezile ngemiyalo elandelayo ngaphambi kokwakha :

$ TOOLCHAIN_PATH=$HOME/toolchain/gcc-arm-10.3-2021.07-x86_64-aarch64-none-linuxgnu/ bin
$ thekelisa PATH=$TOOLCHAIN_PATH:$PATH
$ thekelisa i-ARCH=arm64
$ thekelisa CROSS_COMPILE=aarch64-none-linux-gnu-

I-Yocto SDK
Khiqiza i-SDK endaweni yokwakha ye-Yocto Project ngomyalo olandelayo ngemva kokukhiqiza isithombe esahlukweni esandulele.

$ cd ~/imx-yocto-bsp
$ imithombo yomthombo/poky/oe-init-build-env maaxboard-8ulp/build
$ bitbake avnet-image-full -c populate_sdk

Okukhiqiziwe file yilena: ~/imx-yocto-bsp/maaxboard-8ulp/build/tmp/deploy/sdk/ fsl-imx-wayland-lite-glibc-x86_64-avnet-image-full-armv8a-maaxboard-8ulp-toolchain-6.1- mickledore..sh futhi usebenzise lesi skripthi ukuze ufake i-SDK. Indawo ezenzakalelayo ingu/khetha kodwa ingafakwa noma yikuphi emshinini wokusingathwa.

$ sudo ./fsl-imx-wayland-lite-glibc-x86_64-avnet-image-full-armv8a-maaxboard-8ulp-toolchain-6.1- mickledore.sh
I-NXP i.MX Release Distro SDK isifaki inguqulo engu-6.1-mickledore
=========================================================
Faka uhla lwemibhalo oluqondiwe lwe-SDK (okuzenzakalelayo: /opt/fsl-imx-wayland-lite/6.1-mickledore):
Usuzofaka i-SDK ku-“/opt/fsl-imx-wayland-lite/6.1-mickledore”. Qhubeka [Y/n]?
Iyakhipha
I-SDK…………………………………………………………………………………………………………………………..kuqediwe
Ukuyimisa...kwenziwe
I-SDK isethwe ngempumelelo futhi isilungele ukusetshenziswa.

Uma usebenzisa i-SDK ukuze uhlanganise iphrojekthi, qala ngokukhipha umyalo olandelayo ukuze ulungiselele okuguquguqukayo kwendawo :

$. /opt/fsl-imx-wayland-lite/6.1-mickledore/environment-setup-armv8a-poky-linux

Yakha i-U-Boot endaweni ezimele

Thola ikhodi yomthombo kanye ne-firmware
Ukuze uthole ikhodi yomthombo ye-u-boot, imx-atf kanye ne-imx-mkimage, yenza le miyalo elandelayo:

$ mkdir tmp
$ cd tmp
$ git clone https://github.com/Avnet/uboot-imx.git -b maaxboard_lf-6.1.22-2.0.0
$ git clone https://github.com/Avnet/imx-atf.git -b maaxboard_lf-6.1.22-2.0.0
$ git clone https://github.com/Avnet/imx-mkimage.git -b maaxboard_lf-6.1.22-2.0.0
Landa i-firmware-imx, decompress futhi wamukele i-NXP EULA uma isebenza:
$ wget https://www.nxp.com.cn/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.20.bin
$ chmod +x firmware-imx-8.20.bin
$ ./firmware-imx-8.20.bin
Faka umyalo 'ls' ku view inkomba ye-tmp:
$ ls tmp
firmware-imx-8.20 firmware-imx-8.20.bin imx-atf imx-mkimage uboot-imx
Kuze kube manje, ikhodi yomthombo edingekayo kanye ne-firmware sekulungisiwe.

Hlanganisa umbhalo
Dala iskripthi se-bash kumkhombandlela we-tmp bese ushintsha ifayela le- file imodi:

$ cd tmp
$ touch make_mx8ulp_uboot.sh
$ chmod 766 make_mx8ulp_uboot.sh
$ vi make_mx8ulp_uboot.sh
Kopisha okuqukethwe okulandelayo kusikripthi se-make_mx8ulp_uboot.sh:

Isithombe sokuqalisa se-Maaxboard 8ULP sithi u-boot-maaxboard-8ulp.imx kumkhombandlela wamanje.

Yakha i-Kernel endaweni ezimele

Thola ikhodi yomthombo we-Linux
$ git clone https://github.com/Avnet/linux-imx.git -b maaxboard_lf-6.1.22-2.0.0

Hlola ukuthi okuguquguqukayo kwemvelo kusethwe ngendlela efanele :
$ echo $CROSS_COMPILE $ARCH

Yakha imithombo ye-kernel

$ cd linux-imx
$ yenza disclean
$ yenza i-maaxboard-8ulp_defconfig
$ yenza -j4

Faka umyalo 'ls' ku view Isithombe kanye ne-dtb files ngemva kokuhlanganiswa.
