# FAQ / Betaflight - no gyro, no blackbox, no baro

Betaflight 4.4 and later introduces "cloud-build" as presented in 4.4 release notes here: https://betaflight.com/docs/wiki/release/Betaflight-4-4-Release-Notes#1-cloud-build

For cloud-builds, the 3 typical things that a target's definition might lack is the acc/gyro, baro, & flash-chips.

Although it is the manufacturers' responsibility to keep targets updated, Betaflight developers can easily fix these issues upon reports of missing defines.

Recommend using a nightly Configurator as there are some worthy bug-fixes: https://github.com/betaflight/betaflight-configurator-nightlies/releases (Note: release 10.9 has a bug where you are ***required*** to enable expert-mode on the flashing tab; otherwise the UI will ignore any custom defines requested.)

Two proper routes to take is :
option 1) iterate through all the defines and report exactly which one works for specifically what flight-controller.
option 2) use the integrated support-system along with discord comment as per documenation https://betaflight.com/docs/wiki/configurator/firmware-flasher-tab#board-defines

i.e.

* **option 1**) Enable **`Expert-mode`** on `Firmware Flasher` tab (***required*** in 10.9, or prefer to use a nightly configurator). Then use the baro/flash/etc defines as reported by 4.4 release notes.
Prefer to cloud-build & flash `4.4-dev` or `4.5-dev` rather than "release". (at this time until things settle as "stable")

* **option 2**)
- 1. Flash your board with the **Core-Only** toggle enabled.
- 2. Use **`Submit Support Data`** button on CLI tab.
- 3. Post support IDs to Betaflight discord's `#cloud-build-issues`, explaining what you need.
- 4. Optionally, Include info from CLI status command.
- Devs will add the define(s) to source-code.
- Note: devs will not add defines for FC's that are actually clones, but prefer the clones to have their own target. Please check if your clone already has a specific target.
### Custon Defines:
* Any defines as listed on https://betaflight.com/docs/development/manufacturer/manufacturer-design-guidelines#42-definitions-for-targets but user may exclude the `USE_` prefix.
