Hi,

you can try use this way to compile linux.

---------------tool chain-------------------

$wget https://developer.arm.com/-/media/Files/downloads/gnu/11.2-2022.02/binrel/\

$gcc-arm-11.2-2022.02-x86_64-aarch64-none-linux-gnu.tar.xz

$tar xf gcc-arm-11.2-2022.02-x86_64-aarch64-none-linux-gnu.tar.xz

$rm -f gcc-arm-11.2-2022.02-x86_64-aarch64-none-linux-gnu.tar.xz

$export PATH=`pwd`/gcc-arm-11.2-2022.02-x86_64-aarch64-none-linux-gnu/bin:$PATH

$export ARCH=arm64

$export CROSS_COMPILE=aarch64-none-linux-gnu-

------------building Yocto----------------

git clone -b kirkstone https://git.yoctoproject.org/poky

git clone -b kirkstone https://git.yoctoproject.org/meta-intel-fpga

source poky/oe-init-build-env ./build

echo 'MACHINE = "cyclone5"' >> conf/local.conf

echo 'BBLAYERS += " ${TOPDIR}/../meta-intel-fpga "' >> conf/bblayers.conf

# Uncomment next line to add more packages to the image

# echo 'CORE_IMAGE_EXTRA_INSTALL += "openssh gdbserver"' >> conf/local.conf

bitbake core-image-minimal

ln -s $ROOTFS_TOP/cv/build/tmp/deploy/images/cyclone5/core-image-minimal-cyclone5.tar.gz $LINUX_BIN/a9/
