Unable to build kernel R32 on NX

I’m following Kernel Customization doc and trying to build kernel R32 on NX.

When I run make ARCH=arm64 O=$TEGRA_KERNEL_OUT tegra_defconfig

It shows:

How should I fix this?

Hi,
The document was about build the customize kernel Image from Host(x86) system.

OK Got it. We’ll try that

A note about something you might run into: If you are cross compiling, you use the ARCH=arm64. You would also need to name your cross toolchain location prefix for that case. If you compile natively on a Jetson, then you leave out both the ARCH= and no cross toolchain path would be specified.
