  • In the bootloader code, this functionality is described in the comments as "forcing the bootloader." Interestingly, there is a similar functionality for the PX4-V2 (Pixhawk) boards, but it was disabled in response to PX4-Bootloader issue #46. It seems reasonable, then, that this functionality should also be disabled in the PX4-V1 code.
  • Flight Controller Porting Guide. This topic is for developers who want to port PX4 to work with new flight controller hardware.. PX4 Architecture. PX4 consists of two main layers: The board support and middleware layer on top of the host OS (NuttX, Linux or any other POSIX platform like Mac OS), and the applications (Flight Stack in src/modules).

    jMAVSim with SITL. jMAVSim is a simple multirotor/Quad simulator that allows you to fly copter type vehicles running PX4 around a simulated world. It is easy to set up and can be used to test that your vehicle can take off, fly, land, and responds appropriately to various fail conditions (e.g. GPS failure).

    Now we have to compile the PX4 code for the OcPoC-Mini, depending on which operating system you prefer the commands are slightly different. We'll start with a stable branch of PX4 which we know is tested and ready to fly; this is generally best practice for further development.
