Driver is not added at this time
This is a workaround for the write timeout that we have seen for some
host computers trying to flash the firmware.
We don't know the root cause of the problem but we do observed the
following:
- For blocking writes with timeout (Pyserial write_timeout=0.5):
write() throws SerialTimeoutException. In systrace we see that the
select() call after write waiting for the write to be finished hangs
and finally times out.
- For blocking writes without timeout (Pyserial write_timeout=None):
write() hangs indefinitely. In systrace we see that the
select() call after write waiting for the write to be finished hangs.
- For non-blocking writes:
write() works but flush() hangs. In systrace we see that
ioctl(fd, TCSBRK, 1) which is (correctly) triggered by termios tcdrain
hangs.
Inspecting USB traffic using usbmon, we can see that the data which is
written actually seems to be sent and looking at responses from the
Pixhawk bootloader and the timings it looks like all the data has
arrived.
This workaround uses non-blocking writes without flushing and this
seemed to prevent the issue from happening so far.
Debugging was done in collaboration with Beat Küng and David Sidrane.
The replay functionality was broken with lockstep. This is an interim
fix for the replay functionality.
In the longer term it would be nice to leverage the lockstep speedup
for the replay.
- Remove unnecessary in between rate limits member vectors.
- Only switch the yaw rate limit in auto modes,
other values stay the same anyways.
- Fill gain vectors with parameters in one line.
With this commit the use cases will be:
Success case:
- booting, no messages about OA, pre-arm check would fail if you try to arm and OA is not yet running
Fail case:
- if OA takes longer than timeout time defined in COM_ONB_BOOT_T, then an error message is triggered.

Since onboard controllers bootup times are hardware dependent, it makes sense to have the possibility to adapt timeout time according to the specific HW.

This allows to perform pre-arm checks and prevent arming if obstacle avoidance is enabled but not yet running.
Added a print once flag to prevent excessive message spamming in QGC.

If we dont explicitly check for pyserial, we can have the case where the
import works but the Serial object creation fails. However, we don't see
this because we have this huge try/catch block which swallows
everything.
With a DLPF of 62.5 Hz, the sampling rate is apperently not 1 kHz anymore,
because the driver got duplicate samples and published only at 128 Hz.
We have to increase the filter back to 500 Hz so that we get 1 kHz sampling
rate, with 250 Hz publications.
