TinyUSB examples includes external repos aka submodules to provide low-level MCU peripheral's driver to compile with. Therefore we will firstly fetch those mcu driver repo by running this command in the top folder repo
```
$ git submodule update --init --rescursive
```
It will takes a bit of time due to the number of supported MCUs, luckily we only need to do this once.
## Build
[Here is the list of supported Boards](docs/boards.md) that should work out of the box with provided examples.
To build example, go to its folder project then type `make BOARD=[our_board] all` e.g
`flash` target will use the on-board debugger (jlink/cmsisdap/stlink/dfu) to flash the binary. We should install those debugger/programmer software in advance. Futhermore, since external jlink can be used with most of the board, there is also `flash-jlink` target for out convenience.
