Having a generic interface over the GPS drivers makes dedicated
functionality for each driver harder. Move the Septentrio driver into
its own module under the `gnss` driver directory, and let it have its
own parameters for only the functionality it requires. This also helps
with adding new features because they only need to be implemented for
the driver that wants it, simplifying testing.
* usb: Added parameter to enable always starting mavlink on USB.
Refactored cdcacm_init into a module and added a paramter to allow always starting mavlink on
USB, also added a paramter to choose the mode. The current default behavior is to wait and listen
for data on USB and auto-detect the protocol (mavlink, nsh, ublox). This results in the mavlink
stream not starting until something else on the mavlink network sends a packet first. The new
default behavior is to always start mavlink.
Added parameters
MAV_USB_ENABLE -- default 1 (always start mavlink on USB)
MAV_USE_MODE -- default 3 (onboard)
* added 3 retries for opening serial port in mavlink, removed sleep before sercon
* added DRIVERS_CDCACM_AUTOSTART to ark-v6x default.px4board
* added CONFIG_DRIVERS_CDCACM_AUTOSTART=y to default.px4board for boards with CONFIG_CDCACM in their nsh/defconfig
* format
* remove PGA460 from COMMON_DISTANCE_SENSOR to save flash
* remove LIS2MDL from COMMON_MAGNETOMETER to save flash
* disable CONFIG_DRIVERS_CDCACM_AUTOSTART for fmu-v5 protected.px4board
* moved and renamed parameters, removed mode logic in mavlink
* changed parameter names, added mode none
* remove parameters from mavlink
- cmake NuttX build wrapper compile in place instead of copying source tree to build directory
- slightly faster skipping necessary copying (depending on system)
- allows debugging in place
- easier to work directly in NuttX following official documentation
- simplifies overall build which should make it easier to resolve any remaining NuttX dependency issues in the build system
- the downside is switching back and forth between different builds always require rebuilding NuttX, but I think this is worth the improved developer experience
- also no longer builds px4io and bootloader in every single build, for most users these rarely change and we're wasting a lot of build time
