Part Number: AM6442
Dear TI team,
I am trying to cross-compile my own kernel module from my Ubuntu machine to my Sitara AM6442 with linux 6.1.33-rt11-g685e771524. I include the standard headers
#include <linux/kernel.h>
#include <linux/module.h>
#include <linux/fs.h>
and I receive the following error:
aarch64-none-linux-gnu-gcc -O2 -c -D__KERNEL__ -DMODULE -Wall -I/home/leon/sdk/board-support/ti-linux-kernel/include -I/home/leon/sdk/board-support/ti-linux-kernel/arch/arm64/include -c -o sm_mod.o sm_mod.c

123 | __ll_sc_atomic64_##op(s64 i, atomic64_t *v)
I have tried various variants of include paths (e.g. "arm" instead of "arm64"), hoping that the required files/definitions would be found, but it does not work. What are the correct include paths that I need?
Many thanks
Leon Rigoni
