Currently, I’m working with Jetson Nano 2Gb, and I facing the problem about assembly when I debug with gdb, I receive

92      __asm__ __volatile__("mrs %[res], daif": [res] "=r" (res)::);
(gdb) 

Program received signal SIGILL, Illegal instruction.
INTERRUPTS_ENABLED () at Sx1278.cpp:92

And this is assembly code that causing that bug

__inline__ int INTERRUPTS_ENABLED(void) {
    int res;
    __asm__ __volatile__("mrs %[res], daif": [res] "=r" (res)::);
    return ((res >> 7) & 1) == 0;
}

__inline__ void ENABLE_INTERRUPTS(void) {
    if (!INTERRUPTS_ENABLED()) {
        __asm__ __volatile__("msr daifset, #2");
    }
}

__inline__ void DISABLE_INTERRUPTS(void) {
    if (INTERRUPTS_ENABLED()) {
        __asm__ __volatile__("msr daifclr, #2");
    }
}

I think this code have a problem in __inline__ int INTERRUPTS_ENABLE(void); function. But I don’t have any idea to fix it.

I have no experience with this problem.

I use this repo to control gpio pin

Some information about my project:

I need to communicate between module Sx1278 (LoRa) and Jetson Nano board.

This is my github for Jetson Nano and module LoRa Ra-02:
github

It’s include Makefile. I just modify some function based on this repo

To running this program, I only use makefile, that generate executable file. I thought it’s caused by toolchain, but I can’t fix it.

Some information: When I use OS raspbian 32 bit it run normally. But when I use OS 64 bit, it’s facing that problem, and my module run on Aarch64 architecture. Jetson Nano don’t just have os version 64 bit.

Has anyone experienced a similar problem when using the JETGPIO library on a 64-bit Jetson Nano or another Aarch64 system? Any suggestions on how to diagnose and fix this issue would be immensely helpful.
