I build a new kernel with Preempt_RT on my jetson nx ,here is step:
cd /usr/src/kernel/kernel-4.9
zcat /proc/config.gz > .config
./scripts/rt-patch.sh apply-patches
make menuconfig
select fully preemptibal kernel
make prepare
make modules_prepare
make -j6 Image
make modules
make modules_install
sudo cp arch/arm64/boot/Image /boot/Image
reboot
when i excute conmand “uname -a”,it’s still old kernel version,it seems new kernel doesn’t work.Is there any wrong step?My L4T version is 32.7.2
