This pushes the metadata files as well as the IO firmware and the
bootloader binary to the SD card.
That way, the files are don't have to be added to the firmware
binary or served via s3 for FLASH_CONSTRAINED targets.
The files are pushed after upload and verified in commander as part of
the preflight checks. If missing, a warning is displayed and arming is
prevented.
This means that an SD card can't be swapped out without reflashing (or
copying over the contents).
- re-enable once the estimator selector respects configured mag
priority (at least initially) or is otherwise able to automatically
prefer an external mag over internal
- for SITL disabled because the full matrix of esitmator instances
(IMUs X mags) was too many topics for logger currently
- 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
