64-bit kernels and 32-bit user-space

Tue May 2 05:55:48 PDT 2023

I am trying to get a kernel crashdump on an embedded router, but it has 
32-bit user-space while the kernel is 64-bit. I tried something simple 
and got following:

# kexec -S
Unsupported machine type: aarch64

Looking in the build directory I only see arch/arm/ folder, but no 
arch/arm64. Is this due to 32-bit user-space? Has someone tried kexec in 
such an environment? Any pointers would be appreciated.

Regards,
Arend
