Kernel crash with BCM2835 version 1.52 and Raspberry Pi 2b

[Pierre HENELLE]

I have the following kernel crash that happens often when using the lib

Can you guys help ?

Could it be because RPi 2b uses BCM2836 and the lib is for bcm2835 ?

Hi

The problem is not the processor version

Do you have the latest version of the library?

Are there any kernel drivers loaded that might conflict with your use of the library?
