Hi,
Please do

  1. Skip the steps of enabling RT kernel. See if the self-built default kernel image is good
  2. Enable RT kernel and check if the built RT kernel image is good

At this moment your built default kernel image and RT kernel image are good. And then please do

  1. Modify generic_rt_build.sh to enable the config to both defconfig and tegra_prod_defconfig:
        --enable CONFIG_HZ_1000
  1. Run the commands to re-generate the config files:
$ ./generic_rt_build.sh "disable"
$ ./generic_rt_build.sh "enable"
  1. Ensure the config is enabled
kernel/kernel-jammy-src/arch/arm64/configs$ grep CONFIG_HZ ./ -r
./.updated.defconfig:CONFIG_HZ_1000=y
./.updated.tegra_prod_defconfig:CONFIG_HZ_1000=y
  1. Build RT kernel image
