# Bare Metal Demo App
|
|
|
|
This directory provides a basic bare metal demo app that demonstrates how to communicate / drive the custom logic in this project.
|
|
|
|
## Build and Load over LiteX-Term
|
|
|
|
The project is built with: ``make -C demo``
|
|
|
|
The project board does not provide extra interfaces to connect to the board, so serial is used here: `$ litex_term --kernel demo/demo.bin /dev/ttyACMX` (ACM due to the use of `usb_acm` UART)
|
|
|
|
You should see the demo app running and should be able to interact with it:
|
|
|
|
```bash
|
|
$ litex_term --kernel demo/demo.bin /dev/ttyACM0
|
|

|
|

|
|
Build your hardware, easily!
