This program assumes that **GPIO PA1** is connected to SPISEL of the Ethernet module. The program output is logged via ITM.
This program assumes that the **SPI1** port is connected to the Ethernet module, and the **GPIO PA1** pin is connected to its SPISEL pin. The program output is logged via ITM stimulus port 0.
#### How-to
1. On a console window, run OpenOCD and debug the example program:
1. Connect your STM32F407 device to the computer. Without changing any code, you may use an STLink V2 debugger. Then, on a console window, run OpenOCD and debug the example program:
```sh
$ nix-shell
[nix-shell]$ run-openocd-f4x

* This socket waits for a single incoming TCP packet on the said port, and sends a TCP packet holding a text of greeting on the port.
* Note that once a greeting is sent, the port is closed immediately. Further packets received by the controller are dropped until the initiator closes the port.
