Dear all,

 

I have a custom board based on a i.MX6Quad with a kernel : 3.14.28-1.0.0_ga+gac92adc.

 

I have an issue with the GPU during the boot. I can see this log :

kernel: [ 42.443570] [galcore]: GPU[0] hang, automatic recovery.

kernel: [ 42.448954] [galcore]: recovery done

 

I searched in the GPU driver code this log and it seems that the driver try to recover the GPU from a fatal error.

 

What can be the cause of this issue ?

 

Thanks for your help.

 

Regards,

 

Sébastien
