This will initialize those structs with zero in all fields not set
and all fields set will only be change once to the final value not
wasting CPU time zeroing it.
This will guarantee that no non-unitialized structs will have
a trash value on from_external causing it to be sent to the
MAVLink channel without need it.
This requires support in the parsers, and thus the ULog file version is
increased.
As long as no data is appended, both, existing pyulog & FlightPlot, can
still read the new logs (they will output a warning).
The replay module will print an error, but still continue.
This will avoid file system corruptions in cases where px4_shutdown_request
is used. However it will not help obviously when the battery is pulled
directly.
For the process usage: we need to measure over a certain period of time,
then we can use the results. To avoid blocking, this does:
- after log is started, initialze the load counters, then one second later
add the results to the log
- after disarming: continue logging for one more second, then add the process
load to the log and stop logging.
- to avoid a delay, 'logger stop' will stop immediately and not log
postflight process usage.
Just to make sure that it will never be used on NuttX. This is not an
architectural limitation, just a memory optimization, since we call
clearenv() on NuttX.
- use uorb queue to not drop any info, only do 2 tasks per cycle
- also print a warning on low stack (which will be added to ulog)
this allows to gather statistics of each task's stack usage over time.
using scanf with %s reads until the first whitespace, which included the
comma (as per C standard and tested on linux). Behavior on NuttX differs.
This makes it work on both Linux and Nuttx.
in particular:
- SW release version (in addition to the git hash)
- OS version (tag + git hash if exists)
- mcu version & revision & UUID
- toolchain version
The uuid can be disabled via parameter, it's enabled by default.
boards define BOARD_NAME, so board_name() is not necessary. HW_ARCH was
just a wrapper around board_name().
This patch simplifies to having only one common method px4_board_name().
