IMX6ULL EVK

[athul_am]

Can someone help with by providing steps for creating an image for the imx6ull evk board.In\ need detailed steps the guides that i have checked is too vague.This is the steps i am using i have not tested this on the board but it will arrive soon and i dont have time to tinker with errors :

1.Installing the dependencies for the build:

    command: sudo apt-get install gawk wget git-core diffstat unzip textinfo gcc-multilib \

    build-essential chrpath socat libsdl1.2-dev xterm

1. Command to clone the yocto repository into the system:

   command : git clone –b dunfell git://git.yoctoproject.org/poky.git

   The repository gets cloned into the system.

1. The build environment is to be initialized.

   command:cd poky

   run the oe-init-build-env build

   command: source oe-init-build-env build

4.Open the conf/local.conf file in the build directory:

  Add the line in the file:

   MACHINE = “imx6ull-evk”

  this specifies the target hardware the image is being build for.

5.Edit conf/bblayers.conf:

   BBLAYERS ?= " \ /home/ahk/poky/meta \

/home/ubuntu/poky/meta-poky \

/home/ubuntu/poky/meta-yocto-bsp \

/home/ubuntu/poky/meta-openembedded/meta-oe \

/home/ubuntu/poky/meta-openembedded/meta-networking \

/home/ubuntu/poky/meta-openembedded/meta-multimedia \

 /home/ubuntu/poky/meta-freescale

“

1. Bake the image :

   command : bitback core-image-minimal

   it will take several hours

7.Flashing into the sd card

# Insert your SD Card

# Type ’£ dmesg | tail’ to see the device node being used, e.g /dev/sdb)

# In case SD to be flash has already some partitions, the host system may have

# mounted these, so unmount them, e.g. ’£ sudo umount /dev/sdb?’.

build $ ls -la ’tmp/deploy/images/*.sdcard’

build $ sudo dd if=tmp/deploy/images/<selected image>-<select machine>.sdcard of=/dev/sdX bs=1M

build $ sync

Thank you

Hello, I hope you are doing well.

You could use our yocto user's guide to create an image to the board.

Basically, the steps are the next:

sudo apt install gawk wget git diffstat unzip texinfo gcc build-essential chrpath socat cpio python3 python3-pip python3-pexpect xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev python3-subunit mesa-common-dev zstd liblz4-tool file locales -y

sudo locale-gen en_US.UTF-8

mkdir ~/bin

curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo

chmod a+x ~/bin/repo

export PATH=~/bin:$PATH

git config --global user.name "Your Name"

git config --global user.email "Your Email"

git config --list

mkdir imx-yocto-bsp

cd imx-yocto-bsp

repo init -u https://github.com/nxp-imx/imx-manifest -b imx-linux-mickledore -m imx-6.1.36-2.1.0.xml

repo sync

Now, you need to select the machine configurations to start to build the image.

In your case I would use:

DISTRO=fsl-imx-wayland MACHINE=imx6ull14x14evk source imx-setup-release.sh -b build_imx6ull

bitbake imx-image-full

To flash the image, I suggest you use UUU and you can use the steps on the next post.

uuu.exe -b sd_all <bootloader> <rootfs (.wic)>

Best regards.

Hi @JorgeCas,

thanks for the reply and sorry for the latest response.I tried the commands and it is working, due to some space issues as i am trying to from a vm

the image is not getting created successfully.Can you please share a link where i can download a preexisting image ? I also need a toolchain for the cross compilation if  it is available.

Hello,

The web page with prebuilt images is the next link.

For the toolchain, please follow this guide build imx-image-full,

Then use:

bitbake imx-image-full -c populate_sdk

Install SDK:

tmp/deploy/sdk/xxx.sh

Use SDK:

source /opt/fsl-imx-xwayland/xxx/environment-setup-aarch64-xxxx

Best regards.
