Segui este tutorial , bem como este < href="https://ubuntuforums.org/showthread.php?t=2010979"> um para configurar um compilador + depurador para o Assembly ARM.
Após o primeiro, executei o comando qemu-arm -singlestep -g 1234 empty e iniciei um novo shell, onde tentei conectar o gdb ao qemu copiando e colando as instruções dadas:

(gdb) file empty
Reading symbols from empty...done.
(gdb) target remote localhost:1234
Remote debugging using localhost:1234
_start () at empty.s:4

(gdb)
No entanto, sempre que tento me conectar com target remote localhost:1234 , há um erro de tempo limite.
Também segui as instruções do segundo tutorial, mas terminei com o mesmo erro de tempo limite. Preciso pré-configurar o qemu?
