I used to the St-write to burn .bin to the STM32F4 and saw the message which I expected. Now, I hope to understand how GPIO init. Hence, I use OpenOCD and arm-none-eabi-gdb to do that. Here, it is my process.

$ minicom 

$ openocd -f /opt/openocd/share/openocd/scripts/board/stm32f4discovery.cfg 

$ arm-none-eabi-gdb main.elf

(gdb) target remote :3333

(gdb) :3333: Connection timed out.

How do I check the port of OpenOCD? Why does it occur timeout?

try target remote localhost:3333

(gdb) localhost:3333: Connection timed out.

It's same.

If it is intermittent, try another USB port. I kept on getting timeouts restarting a debug session in Atollic till I finally found a USB port that did not do it any more.
