- increase stack sizes to run cleanly under stackcheck
- this is likely overkill for most boards, but using stackcheck to set our minimum ensures we have a very safe margin on regular builds and it's something we can currently afford
- remove holybro_durandal-v1_stackcheck from test rack (there's only one unit)
When this triggered it actually just kept printing
"floating point exception" and never recovered. By removing this we can
at least catch it with a core dump, in CI as well as locally.

Ubuntu 20.04 and latest Cygwin come with no Python 2 and no link
from python to python3. To not mess with the system we detect
python3 for seamless support.
- update to NuttX with stm32f4 and stm32f7 SPI DMA internal buffers
- remove explicit DMA buffer allocations from new IMU drivers
- restore original BOARD_DMA_ALLOC_POOL_SIZE
- decrease SPI DMA thresholds based on fmu-v2/v3/v4/v5 bench testing
instead of a static per-driver array.
Reduces BSS RAM usage by a couple of 100 Bytes (linear increase with num
drivers).
Downsides:
- a bit more runtime overhead
- less isolation, locking required
- a bit more complex
* MC_HTE: unitialize with hover_thrust parameter
* MC_HTE: constrain hover thrust setter between 0.1 and 0.9
* MC_HTE: integrate with land detector and velocity controller
* MCHoverThrustEstimator: Always publish an estimate even when not fusing measurements. This is required as the land detector and the position controller need to receive a hover thrust value.
* MC_HTE: use altitude agl threshold to start the estimator
local_position.z is relative to the origin of the EKF while dist_bottom
is above ground

Running the sensors module out of the same WQ thread as the estimator, position, and attitude controllers is a bit safer and prevents potential priority and starvation issues. There is a very small increase in latency (~50 us) between sensors and ekf2 execution (on average). This also saves a little bit of memory (~ 3 kB) and cpu (~1-1.5% depending on the board).
