Hello,

When I was debugging my CX3 UVC project with my own configuration, I encountered the following problem.
Debugging is trapped in the CyCx3UvcAppErrorHandler() API when initializing the MIPI Block module , I want to know if this is a problem with my hardware and I should solve this problem this way, looking forward to your help, thanks a lot.

Hi Yaqi,

The problem can be caused due to the I2C slave connected externally i.e, from the sensor. Please monitor the I2C bus for the cause of read timeout.

Hi

I found out that when status returns 0x45, the problem is this:

CY_U3P_ERROR_TIMEOUT - If an I2C read/write timeout occurs during the operation.\n

I already know what the problem is, what should I do next?

Best Regards,

Yaqi
