Bug report
After updating from 4.1 to dev(4.3.3) - running arducopter - the arducopter is freezes - with no lights blinking, any GSC response/message. Trying running the examples one by one, I got on the BARO a segfault
In this same board with same linux and same kernek I have the 4.1 final and is working fine with any crash or something.

Starting Ardupilot I'm having:
Config Error: Baro: unable to initialise driver
And running the example - BARO_generic

Any clue ?
I'm facing several problems with SPI and beaglebone. First was this crash, now the crash continues in the examples, but ardupilot is running on the master/dev branch. But the load average is hudge - and all examples are running fine and with almost none load average, but anything running with SPI bus the load average increase exponentially.
Try to change DMA_PRIORITY in ardupilot/libraries/AP_HAL_ChibiOS/hwdef/YOUR_HARDWARE/hwdef.dat
like this DMA_PRIORITY SDMMC* USART2* ADC* SPI* TIM* to this DMA_PRIORITY SDMMC* SPI* USART2* ADC* TIM*
There problem was fixex by the PR https://github.com/ArduPilot/ardupilot/pull/24786
