Hi, I am working on AGX Orin with Jetpack R36.4.0. I tried to enable dynamic debug by “make ARCH=arm64 menuconfig” in the folder kernel/kernel-jammy-src. After the modification, I confirm that in the file kernel/kernel-jammy-src/.config, I can find: CONFIG_DYNAMIC_DEBUG=y CONFIG_DYNAMIC_DEBUG_CORE=y But after rebuilding the kernel, the file .config is changed back to the original one and the config “CONFIG_DYNAMIC_DEBUG” is not set. Could you please let me know how to enable dynamic debug on R36.4.0? Thanks!

Thanks for your update! Please close the ticket. I don’t have more questions.

Hi, thank for your quick response! I don’t find CONFIG_DYNAMIC_DEBUG in the two following files: arch/arm64/configs/defconfig arch/arm64/configs/tegra_prod_defconfig But I notice that the config “CONFIG_DYNAMIC_DEBUG=y” is included in the file defconfig_debug.config. Shall I add “CONFIG_DYNAMIC_DEBUG=y” to arch/arm64/configs/defconfig or arch/arm64/configs/tegra_prod_defconfig? Thanks!

Hi, Yes, please add required configs and rebuild kernel and oot modules.

Thanks for your answer! The modification in defconfig works. I notice that the file .config in the folder “kernel/kernel-jammy-src” is updated automatically after building. The configuration “CONFIG_DYNAMIC_DEBUG=y” is inserted. But the modification in tegra_prod_defconfig doesn’t help. Could you please explain the difference between tegra_prod_defconfig and defconfig? What is the purpose of the file defconfig_debug.config?

The issue is closed after updating “defconfig”.

Hi, Would suggest update both tegra_prod_defconfig and defconfig if you would to enable/disable certain configs. There may be potential issues if there is mismatch.

Hi,
Please modify defconfig and tegra_prod_defconfig to enable the configs. Here is a topic for reference:
