Here is strace output:
root at imx6ulevk:~# strace /home/root/tt
execve("/home/root/tt", ["/home/root/tt"], [/* 15 vars */]) = -1 ENOENT (No such file or directory) write(2, "strace: exec: No such file or di"..., 40strace: exec: No such file or directory
) = 40
exit_group(1)                           = ?
+++ exited with 1 +++
