"VPU blocking: timeout" randomly happening

I am using the H.264 encoder on the i.MX6Q (1080P30).

Randomly, the BIT processor seems to be hanging ("mxc_vpu 2040000.vpu: VPU blocking: timeout." from the driver).

I have to reset it to continue encoding. This is not happening often, and it seems to be completely random.

I could encode fine for hours before not seeing it.

Or that can happens just a few minutes before I started encoding.

 

Is-it a known issue ?

 

VPU firmware version: 3.1.1_r46056

VPU library version: 5.4.23

kernel 3.10.17

 

I am doing nothing than encoding, and CPU idle is high (~95%) when the VPU blocks...

I have tried many different H.264 encoding settings, and I am always seeing this issue.

 

Is there a newer version of the VPU firmware, and if yes, where could I grab it ?

 

TIA!

Olivier
