Currently we are operating I2C in 100khz. can you please provide the solution for this issue?

Hello Vineeth,

Can you share your schematics for both the serializer and deserializer side here for review?

Best Regards,

Casey

Hi Casey,

Thank you for your update.

Okay! I will share the schematics. We are updating the camera configurations( gain, exposure ) without stopping the camera stream . one observation is Flickering is low when inserting the delay between each i2cwrite.

Hello Vineeth,

When you have this issue, does the LOCK pin temporarily drop on the 936 side? Does the 936 report any errors in the register related to the FPD-Link or the CSI-2?

Best Regards,

Casey
