Please try whether the attached elf file can be executed to print "Hello World" successfully on your target board.

1. On your host PC create test.c as the following.

#include <stdio.h>

void main()
{
printf("Hello World!");
}

2. Cross compile test.c.

aarch64-linux-gnu-gcc test.c -o test.out

3. Copy test.out to ls1046ardb target board.

root@TinyDistro ~]$ ./test.out
Hello World![root@TinyDistro ~]

You could copy the file to USB storage device. Or setting up networking environment, and use "scp" command to copy the file from the PC to the target board.
