D.1 :


We are trying to make a custom board run px4, based off pixracer [px4_fmu-v4].
Currently Using px4-dev-nuttx container for development.
Bootloader operates and connects with QGC, but after flashing the custom PX4 stack, USB does not start. Serial Debug port is okay, and log is visible.
there are some issues that we need help with.

  1. Bypassing the VBUS for PX4, this has disabled the USB initialization for PX4 after PX4 image flashes.
  2. Adding new flash memory device to MTD
  3. Using non-mavlink communication with external system [arm mcu] over UART.
