this zeros-watchdog was caused by a SPI DMA error on STM32F405:
https://discuss.ardupilot.org/t/crash-with-4-2-0-beta-and-4-3-0-daily-bdshot/83297
we had incorrectly left these internal errors enabled when asserts
were not enabled. That led to a osalSysHalt()
without these we get an spi_fail internal error, caught by the
SPIDevice code
this fixes two issues:
The first issue that if we are missing a log file in the middle of the
list then it was not possible to download recent logs, as we get the
incorrect value for total number of logs. This happened for me with
107 logs, with log62 missing from the microSD. It would only show 45
available logs, so the most recent logs could not be downloaded.
The second issue is that get_num_logs() was very slow if there were a
lot of log files in a directory. This would cause EKF errors and ESC
resets. Using a opendir/readdir loop is much faster (approx 10x faster
in my testing with 107 logs on a MatekH743).
This addition allows for cheap testing of a STM32H755 (dual core). This borrows the setup file STM32H757xx.py, as there are almost no changes between the chips. CRSF in and out, gps, ICM20948, BMP388, settings saving to on board flash all working.
PWM(3) pin change
Changed PWM(3) pin to one exposed on connector
we have seen errors where the BMI088 gets out of sync, so that the 3
axes are rotated. The data is shifted by 4 bytes, so that X=Z, Y=X
and Z=Y
this changes the BMI088 to "stop on full" mode, which is what Bosch
use in their example drivers, and also catches FIFO overrun events and
triggers a full FIFO reset. This should fix the problem with the FIFO
sync
