Hi,

I am working with iMX8MM EVK and Yocto distribution 4.19.35 version

Build Configuration:
BB_VERSION = "1.42.0"
BUILD_SYS = "x86_64-linux"
NATIVELSBSTRING = "ubuntu-16.04"
TARGET_SYS = "aarch64-poky-linux"
MACHINE = "imx8mmevk"
DISTRO = "fsl-imx-xwayland"
DISTRO_VERSION = "4.19-warrior"
TUNE_FEATURES = "aarch64"
TARGET_FPU = ""

I tried to install the spidev module by executing the following command, It throws the below error for 3.5 and 2.0 versions

Hi  Sreedhar A,

aarch64-poky-linux-gcc is in your yocto project. You can move them to your board  and set them to your board's env.

Location: /tmp/sysroots-components/x86_64/gcc-cross-aarch64/usr/bin/aarch64-poky-linux/

Best Regards,

Zhiming

Hi Zhiming Liu,

Thank you for the quick response.

I could locate the aarch64-poky-linux-gcc" in Yocto Build Project.

"aarch64-poky-linux-gcc is in your yocto project. You can move them to your board  and set them to your board's env."

Could you please share the steps to set into the board environment.

My board environment details:

Thank you,

For example,you copy the aarch64-poky-linux/ to the board's /opt .Then vim the /etc/profile and add 'export PATH=$PATH:/opt/aarch64-poky-linux' to the last line.

Remember 'source /etc/profile'

Hi,

You can try to use the toolchains in python 2.7.

/tmp/work/aarch64-poky-linux/python/2.7.16-r0/recipe-sysroot-native/usr/bin/aarch64-poky-linux/

or
