Hello everyone! I am working on a new NuttX-based firmware. On this application a hardware board will be able to communicate through UART with a Linux system.
There is still some testing and development to be done on this Linux program, so I thought that this is a great use for the simulator. Instead of passing actual hardware boards to every developer, they can start-off with a simulator app for the first steps. I am also thinking that later, appropriate tests may be included in our CI. That's much more convenient than actually connecting hardware on the CI server. I tried to build the firmware for the simulator target. It was quite straightforward, and everything works correctly (with mocked board drivers of course). Now I need to implement this UART communication with the host. I am not sure if this is possible, is it? I saw that there are simulated UARTs, but they are poorly documented, and I am not sure whether this is their purpose. I tried using them, but I didn't have any luck, NuttX seems that it cannot open the device for writing. Any ideas?
