DM385 2A engine problems

Other Parts Discussed in Thread: DM385

Hello,

I am using DM385 IPNC. After adjusting 2A Engine to TI or APPRO following both problems can be observed after some time (when moving camera):

1.) Stream hang up => Console shows following message: "I2C arbitration lost !!!".

2.) auto exposure hang up => Console shows following message: "[m3vpss] I2C: timed out in wait_for_bb: I2C_IRQSTATUS=1000". In this case only auto exposure or white balancing engine don't work.

When adjusting 2A Engine to NONE, this behaviours cannot be observed.

Does anybody know cause of this problem and how resolve it?

Thank you very much!
