Endless Pinging - tx_stm32f407

This program demonstrates the Ethernet TX capability on an STM32F407 board connected to an ENC424J600 module via SPI. Once loaded and initialised, a specific ping packet is sent (broadcasted) every 100ms. Such a packet has the following properties:

• Destination MAC Address: ff-ff-ff-ff-ff-ff
• Source MAC Address: 08-60-6e-44-42-95
• Destination IP Address: 192.168.1.231
• Source IP Address: 192.168.1.100
• Frame Length in Bytes: 64

Note that this program uses ITM for logging output.

How-to

1. Prepare the Rust and Cargo environment for building and running the program on STM32F4xx Cortex-M platforms.

2. Install itm on Cargo:

   cargo install itm
   

   If necessary, add your installation location (~/.cargo/bin by default) to $PATH.

3. Connect your STM32F407 device to the computer. Without changing any code, you may use an STLink V2 debugger.

4. Run OpenOCD with the appropriate configuration files (e.g. interface/stlink-v2.cfg, target/stm32f4x.cfg).

5. With OpenOCD running, build and run this program:

   cargo run --release --example=tx_stm32f407 --features=stm32f407
   

   Use appropriate GDB commands such as c for continuing.

6. On a separate console window, monitor and observe the ITM output, which is located at the same directory as you started OpenOCD:

   itmdump -f itm.log -F
