| 46 | +## Build |
| 47 | +Build fmu firmware for quadcopter |
| 48 | + |
| 49 | +``` |
| 50 | +cd FMT-Firmware/taget/sieon/s1 |
| 51 | +scons -j4 |
| 52 | +``` |
| 53 | + |
| 54 | +> -jN allows N jobs at once which makes your build process quicker. |
| 55 | +
|
| 56 | +For other vehicle, such as fixwing, using |
| 57 | + |
| 58 | +``` |
| 59 | +scons -j4 --vehicle=Fixwing |
| 60 | +``` |
| 61 | + |
| 62 | +## Download |
| 63 | + |
| 64 | +### Download FMU Firmware |
| 65 | +Currently there are 3 ways to download fmu firmware to hardware. |
| 66 | + |
| 67 | +1. **Donwload Script**: Enter `python3 uploader.py` in the Cubeorange directory. Then connect your hardware via usb. |
| 68 | + |
| 69 | +``` |
| 70 | +(fmt) E:\GitRepository\FMT-Firmware\target\cubepilot\cubeorange>python uploader.py |
| 71 | +waiting for the bootloader... |
| 72 | +Attempting reboot on COM30 with baudrate=57600... |
| 73 | +If the board does not respond, unplug and re-plug the USB connector. |
| 74 | +Not found fmt_fmu,please connect fmt_fmu! |
| 75 | +Not found fmt_fmu,please connect fmt_fmu! |
| 76 | +Attempting reboot on COM3 with baudrate=57600... |
| 77 | +If the board does not respond, unplug and re-plug the USB connector. |
| 78 | +Not found fmt_fmu,please connect fmt_fmu! |
| 79 | +
|
| 80 | +Found board id: 140,0 bootloader version: 5 on COM29 |

| 92 | +``` |
| 93 | + |
| 94 | +> If the `"ModuleNotFoundError: No module named 'serial'"` error occurs, indicating that the **pyserial** component is missing, enter `pip3 install pyserial` to install. |
| 95 | +
|
| 96 | +2. **QGC**: Go to *Firmware Setup* page,then connect your hardware to PC with a usb cable. In pop-up diaglog,select *Advanced Settings->Custom firmware file* with FMT firmware to download. |
| 97 | + |
| 98 | +  |
| 99 | + |
| 100 | +3. **J-Link**: If you have a JLink, you can connect it to board debug port download the firmware. For more information, please check the [Debug](https://firmament-autopilot.github.io/FMT-DOCS/#/introduction/debug) section. |
| 101 | + |
| 102 | +> Be careful do not override the bootloader! |
| 103 | +
|
| 104 | +When system is up and running, the system banner is output via serial0 or you can view it by entering `boot_log` in QGC Mavlink Console. |
