Flash kernel in jetson agx

There are two kernel kernel images as follows:
a.JetPack_4.5.1_Linux_JETSON_AGX_XAVIER/Linux_for_Tegra/kernel
b.JetPack_4.5.1_Linux_JETSON_AGX_XAVIER/Linux_for_Tegra/rootfs/boot

So after re-flashing the machine, which place will take effect?

Hello @mailonghua ,

The kernel that the board will use is the one in Linux_for_Tegra/kernel in other words option a.

If you create a custom kernel you should copy it to Linux_for_Tegra/kernel directory before flashing.
