I installed Ubuntu terminal as now Windows 10 supports it. I built the Nuttx RTOS using the terminal but in Ubuntu I cannot access USB devices except for a pen drive.

How can I flash the bin file to stm32f4developer?

You can use windows tools. All of the files in the Ubuntu "sandbox" can be access by Windows tools running outside of that sandbox. In the top-level NuttX README:

Accessing Ubuntu Files From Windows

In Ubuntu Userspace for Windows, the Ubuntu file system root directory is at:

%localappdata%\lxss\rootfs

Or

C:\Users\Username\AppData\Local\lxss\rootfs

However, I am unable to see my files under the rootfs\home directory. After some looking around, I find the home directory %localappdata%\lxss\home.

With that trick access to the /home directory, you should actually be able to use Windows tools outside of the Ubuntu sandbox with versions of NuttX built within the sandbox using that path.

  • Disclaimer: I haven't actually tried what I suggest. It just seems to be reasonable. But when using GDB there might be some issues with paths in the ELF binaries. GDB might have issues locating source files. I don't know for certain. – user6711188 Feb 25 '18 at 13:35

As user6711188 explained you can access your home at %localappdata%\lxss\home or you can copy the nuttx.bin directly to Windows side:

$ cp nuttx.bin /mnt/c/ProgramData/

You will need to configure Windows Explorer to show Hidden files, this way you could see the nuttx.bin at C:\ProgramData
