[Paparazzi-devel] Lia 1.1. w. Aspirin 2.2 - system freeze and no kill switch

[Sergey Krukowski]

Hi Michal!
It's really pity if something like this happens.
Actually on STM32 the PWM generation doesn't work from sys_timer, each PWM  
channel is controlled by its separate timer channel, so if the main  
oscillator still works and clocks timers, the PWM will be further  
generated. Anyway, yes, there was a some kind of program error somewhere,  
probably hardware caused.
If you are using an external imu, the problem could be in a communication,  
however it's rather unlikely using a serial connection.
The first advise would be to try repeat this error on the ground to find  
the possible reasons for it.
Regards,
Sergey
